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 on page 10-
15. One or more trips
have occurred with a Value greater than 32. See the
list.
