Description
Possible Reason for Trip
DCRP
VDC RIPPLE
♦
The dc link ripple voltage is too high. Check for a
missing input phase.
DBSC
BRAKE SHORT CCT Brake resistor overcurrent
♦
Check brake resistance is not less than minimum
value allowed
♦
check wiring and brake resistor for earth faults
OSPD
OVERSPEED
♦
Speed feedback > 150% for 0.1 seconds
ANIN
ANALOG INPUT ERR
♦
4-20mA analog input current > 22mA could damage
the input circuit
DBCT
INT DB RESISTOR
♦
Braking mode set to INTERNAL (future use only).
Set to EXTERNAL and connect an External Braking
Resisitor if braking is required.
TRIP
UNKNOWN
♦
An unknown trip - refer to Parker SSD Drives
TR32
OTHER
♦
Refer to OTHER in Appendix D: TRIPS STATUS.
One or more trips have occurred with a Value greater
than 32. See the list.
