1 00:00:00,695 --> 00:00:11,773 In the beginning, it was mentioned that the switching module is responsible for supplying power for the amplifier module. 2 00:00:11,798 --> 00:00:23,367 Two flats are used to establish the connection between the command of the micro and the amplifier module. 3 00:00:23,402 --> 00:00:35,015 In this section, the connection between the complete Main Switching and the front panel is established through this IDC. 4 00:00:35,204 --> 00:00:41,907 First, we explain the connections between the switching module and the amplifier. 5 00:00:42,064 --> 00:00:53,477 The switching module must supply the amplifier module with power through the output voltages. 6 00:00:53,720 --> 00:01:03,688 In this section of the switching module, the external eight-pin phoenix has 12 volts, 7 00:01:03,713 --> 00:01:27,296 the phoenix in the middle of the GND and the next phoenix have -12 volts that in these cables, blue is -12, black is earth and red is 12 volts. 8 00:01:27,798 --> 00:01:37,438 These cables are responsible for supplying current phases of the amplifier with power. 9 00:01:37,603 --> 00:01:43,290 Before connecting it, we need to explain the amplifier module. 10 00:01:43,315 --> 00:01:55,087 The amplifier module, just like the switching module, consists of a middle section and two sides called incomplete and complete sides. 11 00:01:55,196 --> 00:02:01,360 There are differences between the complete and incomplete sides of the amplifier module. 12 00:02:01,362 --> 00:02:08,352 On the complete side, every one of these modules which is called controller, 13 00:02:08,377 --> 00:02:23,454 is related to a current or voltage phase and this controller at the top is related to the VL1 phase and the other is related to VL2 while the one at the bottom is related to VL3. 14 00:02:23,494 --> 00:02:34,806 By looking at the front panel, you can see that VL1, VL2 and VL3 are in accordance with the GND. 15 00:02:34,947 --> 00:02:39,759 The current phases are in this section. 16 00:02:39,852 --> 00:02:54,142 lA1, lA2 and lA3 that are connected to lA1, lA2 and lA3 front panel through phoenixes and cables in relation to earth. 17 00:02:54,112 --> 00:03:00,259 In the incomplete side of the amplifier, there are five phases. 18 00:03:00,423 --> 00:03:09,821 This is the DC output voltage which is located here in the front panel. 19 00:03:09,846 --> 00:03:15,727 This is the DC output voltage which is located here in the front panel. 20 00:03:15,923 --> 00:03:27,227 here lB1, lB2 and lB3 in the front panel are connected to lB1, lB2 and lB3 in relation to earth. 21 00:03:27,252 --> 00:03:31,595 There is a difference between the incomplete and complete sides. 22 00:03:31,620 --> 00:03:41,985 . As you can see, there are six phases in this section including three voltage phases and three current phases which have been explained before. 23 00:03:42,010 --> 00:03:53,869 On the incomplete side, there are five phases including one voltage phase of group B and one DC phase and three current phases of group B. 24 00:03:53,924 --> 00:04:05,768 Another difference is that on the complete side there is a fan controller module amplifier while there is no such thing on the incomplete side of this module. 25 00:04:05,846 --> 00:04:17,025 On the whole amplifier module, in addition to the main module which is the middle amplifier module, 26 00:04:17,151 --> 00:04:34,173 there are two mains on the two sides just like the switching module where the incomplete and complete sides are separated. 27 00:04:34,198 --> 00:04:44,876 In the amplifier module, after opening these screws we can separate these two mains and solve the problems of the module. 28 00:04:44,901 --> 00:04:52,690 Also, there are three sensors on every side of the module that are located on the output of the current phases. 29 00:04:52,729 --> 00:05:05,180 If we connect to the software, we can see the temperature of lA1, lA2 and lA3 sensors as well as lB1, lB2 and lB3 sensors which is the same temperature as the room temperature. 30 00:05:05,329 --> 00:05:14,914 By drawing current from current phases, the temperature of these sensors rises. 31 00:05:14,993 --> 00:05:24,211 As soon as the temperature of the first sensor reaches 60 degrees, we get a Thermal error of the amplifier in the software. 32 00:05:24,235 --> 00:05:36,968 Now we connect the electricity that is being taken from the switching module side to the amplifier. 33 00:05:37,039 --> 00:05:43,952 If you place the amplifier in front of yourself like this, 34 00:05:44,069 --> 00:06:04,062 there are two phoenixes on the right side that are responsible for supplying VL1, VL2 and VL3 35 00:06:04,112 --> 00:06:20,898 voltages and there are five phoenixes on the left side that are responsible for supplying lA1, lA2 and lA3 current phases. 36 00:06:20,946 --> 00:06:33,342 This black wire which comes from the power of the phoenix in the middle is connected to the phoenix number one on the left side at the top. 37 00:06:35,623 --> 00:06:48,513 Two red wires that carry a 12 volts DC, are connected to this section. 38 00:06:50,529 --> 00:07:03,732 Also, the blue wire carrying -12 volts is connected to these phoenixes. 39 00:07:03,959 --> 00:07:16,107 So, now we have connected the power of lA1, lA2 and lA3 current phases to the amplifier through the switching. 40 00:07:16,311 --> 00:07:24,029 In the next part, we connect the power of VL1, VL2 and VL3 voltage phases. 41 00:07:24,371 --> 00:07:50,403 As mentioned before, this phoenix here, the wire at the center of the GND and the left side of the red 300-volt wire and at the right side which is the blue -300-volt wire goes through resistances. 42 00:07:51,140 --> 00:07:57,341 We connect these two phoenixes to the power of the voltage phases. 43 00:07:57,366 --> 00:08:08,036 When we connect the switch, we must have 600 volts between the two ends of these phoenixes. 44 00:08:10,482 --> 00:08:24,685 So, in the first step, we took the power of current and voltage phases from the switching and connected it to the amplifier. 45 00:08:25,412 --> 00:08:33,185 As soon as switch number one is connected, 46 00:08:33,365 --> 00:08:42,060 the output of the voltages reaches here and enters the amplifier module through these cables. 47 00:08:42,295 --> 00:08:59,654 Also, from this part, a flat is connected to the amplifier module to connect the command of the micro and the SPI signals. 48 00:08:59,764 --> 00:09:11,919 Each of these two IDC Latches that are located on the right and left sides of the Main Switching module is related to one side of the amplifier module. 49 00:09:11,967 --> 00:09:20,724 If we connect this cable to this part, the commands will not be executed correctly. 50 00:09:28,865 --> 00:09:34,740 If by initializing the VL1, a Self Calibration error will appear. 51 00:09:34,811 --> 00:09:46,297 The electricity for the complete side of the amplifier must be taken from the right side of the Main Switching. 52 00:09:46,407 --> 00:09:56,234 By injecting voltage into this side of the module and testing it, 53 00:09:56,362 --> 00:10:06,516 we need to take the flat from the left side of the switching module. 54 00:10:06,541 --> 00:10:27,304 When the device is assembled, both sides of the device are electrified simultaneously and we connect the flat. Just note that the flat that is connected to the complete side of the amplifier must come from the right side of the Main Switching. 55 00:10:27,329 --> 00:10:36,017 So far, have connected power to current and voltage phases as well as the flat that establishes the connections. 56 00:10:36,111 --> 00:10:52,330 We turn the device on. Each of these controllers has a series of boot loaders that are put on the STM32 IC 57 00:10:52,416 --> 00:11:08,567 and when they are functioning properly, their LED blinks like this. 58 00:11:08,716 --> 00:11:26,656 When we connect to the software, usually we can see this earth error which appears if the related wire is not connected. 59 00:11:26,681 --> 00:11:33,539 We connect the earth wire and by clearing the error it disappears. 60 00:11:33,564 --> 00:11:41,805 Now, this part is electrified and the electricity reaches the amplifier module through these cables. 61 00:11:42,125 --> 00:11:54,070 By looking at the monitor, you can see four temperatures including Sensor Ia1=24˚c, 62 00:11:54,111 --> 00:12:08,282 Sensor Ia2=25˚c, Sensor Ia3=25˚c and Heatsink1 =25˚c. 63 00:12:08,585 --> 00:12:28,295 By detaching one of these sensors, for example, la1, an error is displayed in the software which can be cleared by selecting Clear Error. 64 00:12:28,320 --> 00:12:33,430 The sensor we just detached displays zero-degree temperature. 65 00:12:33,471 --> 00:12:39,977 By reconnecting the sensor, 24 degrees is displayed in the software again. 66 00:12:46,032 --> 00:12:59,618 To view the heat sink sensor, we first need to turn off the device. It was mentioned that there are three sensors on every side of the module which are related to the currents and two sensors are related to the heat sink. 67 00:13:17,196 --> 00:13:37,250 This part is the heat sink and the sensor is located in this part of the heat sink and is connected to the Main by this pin header. 68 00:13:37,868 --> 00:13:49,040 lb1, lb2 and lb3 and the sensor related to the heat sink number two are located in this part and 69 00:13:49,048 --> 00:14:01,485 connected to the Main by this pin header and its value is read by this Max1202 and displayed in the software. 70 00:14:01,579 --> 00:14:13,805 So, there are three sensors in this part and one sensor at the bottom and four more sensors in this part that are read by this Max. 71 00:14:14,282 --> 00:14:30,883 If current is drawn from any of these phases, these temperatures increase and as soon as the first temperature reaches 60 degrees a Thermal error of the amplifier will be displayed. 72 00:14:31,087 --> 00:14:41,977 Sometimes, any of these LN35s may have a problem in reading or this connection cable is damaged. 73 00:14:42,024 --> 00:14:48,977 This temperature displays, for example, Ia1 300 degrees as soon as the device is connected. 74 00:14:49,002 --> 00:14:53,486 This means that when the device is connected to the software, 75 00:14:53,511 --> 00:15:04,285 it displays an error because it has a temperature above 60 degrees and this error does not go away no matter how many times you clear the error unless the Thermal error is disabled in the software. 76 00:15:04,307 --> 00:15:08,241 But, even by doing this, some other problems may be caused. 77 00:15:08,266 --> 00:15:24,565 So, as soon as you notice this unusual temperature, you need to start looking for a solution to solve this problem. 78 00:15:24,745 --> 00:15:35,838 We connect the flat cable that transfers the commands. 79 00:15:44,292 --> 00:15:51,062 As you can see, the temperatures are as follows: Temperature Sensor Ia1=25˚c, 80 00:15:51,087 --> 00:15:59,736 Temperature Sensor Ia2=25˚c, Temperature Sensor Ia1=25˚c and Temperature Heatsink1 =25˚c. 81 00:15:59,906 --> 00:16:04,686 Also, Temperature Sensor Ib1=0˚c, Temperature Sensor Ib2=0˚c, 82 00:16:04,711 --> 00:16:13,595 Temperature Sensor Ib3=0˚c and Temperature Heatsink2 =0˚c which are related to this side and since the flat is not connected to this section yet, 83 00:16:13,635 --> 00:16:16,432 zero is displayed as their temperature. 84 00:16:16,457 --> 00:16:24,103 Now we turn the device off and connect the flat of the side of the incomplete temperature to check them. 85 00:16:24,128 --> 00:16:34,197 When we want to check the incomplete side of the amplifier module, we need to connect the left side of the flat from the switching. 86 00:16:34,268 --> 00:16:44,447 Then, we turn the device on and this time temperatures of lb1, lb2, lb3 and Heatsink2 must be displayed. 87 00:16:45,151 --> 00:17:04,997 So, if any of these temperatures is unusual and there is a Thermal error of the amplifier, we need to solve the problem considering the faulty sensor. 88 00:17:05,022 --> 00:17:10,730 Sometimes, temperatures of sensors one, two, three and four are all wrong. 89 00:17:10,762 --> 00:17:19,582 The tin of this IC which is related to reading temperatures may have a problem or the IC itself may be damaged. 90 00:17:19,699 --> 00:17:29,215 But if only one of the temperatures is being displayed wrongly, 91 00:17:29,240 --> 00:17:38,038 probably this IC is healthy and it is possible that the LV35 senor which can be seen easier by opening the modules, has a problem; 92 00:17:38,063 --> 00:17:46,764 also, it is possible that this cable which is connected from LN35 bases to this pin header has a problem. 93 00:17:47,273 --> 00:17:54,280 We turn the device off and turn the module toward the complete side. 94 00:17:54,460 --> 00:18:25,247 If you enter the amplifier in any current or voltage phase, every phase of Va1, Va2 and Va3 voltages has two MOSFET, N and P. 95 00:18:25,272 --> 00:18:37,741 Also, current phases l1a, la2 and la3, just like current voltages, have two MOSFET, N and P.
