Evaluation Kit EASYKIT AUX DRIVES (FS50R07W1E3_B11A)
- The nominal output frequency has to be applied with CAN Message:
CAN-ID 11hex, Signal Name PFacNom, Data Type Unsigned, Bit Start 0, Bit Length 16, Unit Hz Q6 (64 ↔ 1
Hz)
- The target output frequency has to be applied with the CAN Message:
CAN-ID 10hex, Signal Name DFacSet, Data Type Signed (negative value for change of rotation direction), Bit
Start 16, Bit Length 16, Unit Hz Q6 (64 ↔ 1 Hz)
- The motor starts to run after CAN Message:
CAN-ID 10hex, Signal Name DEnable, Data Type Bit, Bit Start 0, Bit Length 1
- The target frequency can now be continuously adjusted and will be slowly ramped to these new
values.
4.3 Mode 3 (Jumper): CAN controlled low side single pulse test
The CAN controlled mode (required jumper position see Figure 8) allows single pulse switching tests on an
arbitrary low side switch without the need of a function generator. The easiest way to use the CAN
functionality is given with the CAN terminal function. Please see chapter 5 for more information of this low
cost terminal solution. The single pulse test is a useful mode if you want to test turn-off overvoltages. For
these tests a power inductor has to be connected between the phase output and DCL+ connection like in
standard double pulse test benches (see Figure 22, Figure 24, Figure 26, Figure 28 for pulse test
configurations).
- This mode can be entered if a Jumper is placed on the diagnosis header between pin 12 and 13
(similar to Mode 2).
- Following CAN Message is required to enter single pulse testing:
CAN-ID 10hex, Signal Name DSglPulse, Data Type Bit, Bit Start 2, Bit Length 1
- The switch has to be selected with CAN Message (multiple or a single switch can be selected):
CAN-ID 10hex, Signal Name DSglPulseULs, Data Type Bit, Bit Start 3, Bit Length 1
CAN-ID 10hex, Signal Name DSglPulseVLs, Data Type Bit, Bit Start 4, Bit Length 1
CAN-ID 10hex, Signal Name DSglPulseWLs, Data Type Bit, Bit Start 5, Bit Length 1
- The pulse length has to be applied with CAN Message:
CAN-ID 10hex, Signal Name DSglPulseLength, Data Type Unsigned, Bit Start 16, Bit Length 16, Unit µs Q0 (1
↔ 1 µs, pulse length is limited to a maximum of 500 µs)
- Toggling following CAN Message from 0 to 1 applies the programmed pulses to the output
CAN-ID 10hex, Signal Name DEnable, Data Type Bit, Bit Start 0, Bit Length 1
4.4 Status LEDs
The status led’s indicates to the operator in a very fast way several failure and operating mode conditions of
