Motor supply
Supply source Click CIBANO 500 to supply the motor with CIBANO 500.
Click External source if the motor is supplied from the station supply or
battery without any connection to CIBANO 500 or if the station battery is
connected to the VIN section and supplied, for example, via the B4 socket.
Note: We do not recommend supplying the motor with undervoltage. Doing
so does not provide any additional useful information and can cause
degradation of the motor operation over time.

1. Only available if the trip and/or close signals are configured on the IOB1 module.
2. Only available in the guided test workflow and if CIBANO 500 is selected as source
3. Data taken from the nameplate
4. Only available if Control board is selected as supply source.
5. In general, we recommend the maximum current of 100 A for maximum accuracy. If during a test the time the circuit breaker
is closed should be longer than 1.5 s you might necessarily reduce the test current to drive the current for the whole test
duration. Normally, times of 1.5 seconds are however unproblematic.
