Brake Chopper 0 2 0 504
0 = Disabled
1 = Enabled: Always
2 = Run state
Brake chopper
level
0 911 V varies 1267
Brake chopper control
activation level in volt.
For 240V Supply:
240*1.35*1.18 = 382V
For 400V Supply:
400*1.35*1.18 = 638V
Please note that when
brake chopper is used the
overvoltage controller can
be switched off or the
overvoltage reference level
can be set above the brake
chopper level.
