CTIVE BRAKING LIGHT STAYS ON ALL THE TIME

System voltage is too high or high harmonic content is present. Check
main system rectifier input AC voltage. Refer to the DC bus trigger level
found in Table 2-1. The undistorted main system rectifier AC input voltage
should always be less than DC bus trigger level / 1.414.

Note: If the measured DC bus (in standby) is greater than the RMS
line voltage*1.414, then harmonic distortion may exist. Consult the
project engineer for the appropriate corrective action.

Setpoint too low. The DC bus setpoint pot on the main control board may
have been tampered with. If this is a possibility, then the module needs
to be sent in for recalibration.

Wrong braking module installed. Check the module chassis sticker for
the part number. Refer to Section 2.2 of this manual and verify that the
sticker information represents the correct part number for your application
and voltage levels. Remove and replace as required.

Main control board has gone bad. Module needs to be sent in for repair.

RECHARGE

Verify the polarity of the connection to the DC filter capacitors of the drive.
If this connection is reversed, the commutation diode effectively shorts
the DC bus and will not allow the drive to go through precharge.
