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 10-16. One or more trips
have occurred with a Value greater than 32. See the
list.
