72 Standard Commissioning Process
• 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.
• 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)
DANGER For testing the MCB make sure the MCB is racked out into test
position. These tests must be made without medium voltage connected.
