•
Configurate and test the IO signals, such as control supply monitoring and door
interlock.
Note: Including the logic test, refer to the DriveStartup.
MCB testing
The Main circuit breaker (MCB) is the connection to medium voltage and plays a major
role in all safety concepts of the drive. By that it has to be tested carefully.
DANGER For testing the MCB make sure the MCB is racked out into test
position. These tests must be made without medium voltage connected.
•
De-energize MCB, so during MCB test, main power will not be introduced to drive.
•
Put MCB in remote control mode.
•
According to the DriveStartup instruction, conduct all the steps below. Observe the
MCB control and feedback signals in the graph.
a. 11.01 DIO status bit0 – MCB trip command (-1)
b. 11.01 DIO status bit1 – MCB status closed
c. 87.10 AC500 CPU DI status bit2 – MCB OFF command (front door)
d. 87.10 AC500 CPU DI status bit3 – MCB ON command (front door)
e. 87.10 AC500 CPU DI status bit4 – MCB status open
f. 87.13 AC500 CPU DO status bit0 – MCB ON command
g. 87.13 AC500 CPU DO status bit1 – MCB OFF command (-1)
