Evaluation Kit EASYKIT AUX DRIVES (FS50R07W1E3_B11A)
4 Operating Modes and LED status
4.1 Mode 1 (Default): Self test, soft start, and motor rotation
This mode is selected per default in the standard delivery condition. After the Evaluation Kit has an
appropriated supply voltage, first a self test is performed and after PASS result the phase output is ramped in
a soft start function to a fixed output frequency. The induction machine is running open loop. All of these
items are performed automatically and it requires no user interaction, which makes first test “Easy”.
Safety Warning: Please note that the motor is starting to rotate automatically in this operating mode.
Make sure that the motor is fixed properly and a motor rotation will not lead to dangerous situations
for persons in the near environment.
4.2 Mode 2 (Jumper): CAN controlled mode for output frequency and voltage
If a Jumper is placed on the diagnosis header between pin 12 and 13, the Evaluation Kit runs in CAN Mode.
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.
Figure 8 Required jumper position for enabling the CAN controlled mode.
After the self test routine is successfully passed it waits for CAN messages. In this mode the output
frequency and voltage for the motor can be programmed to adjust the motor speed.
Following CAN Messages are minimum required to get the motor running:
- The nominal output voltage (line to line) has to be applied with CAN Message:
CAN-ID 11hex, Signal Name PVacNom, Data Type Unsigned, Bit Start 16, Bit Length 16, Unit V Q4 (16 ↔ 1 V)
