DESCRIPTION OF PARAMETERS
4.1 Basic
parameters
2.1.1
Brake Chopper Level (ID1267)
Brake chopper operation level in volts. This is the DC link voltage level when the BCU
starts to discharge the capacitors through the brake resistor.
2.1.2
ID Run (ID631)
This parameter is used for manual identification for brake resistor connection. Brake
chopper unit makes automatic identification during every power-up. However, if resistor
connection is changed during service, ID Run can be executed manually with this
parameter by setting the value “1=ID Run”.
