Description
Brake resistor overcurrent
Trips and Fault Finding
Possible Reason for Trip
 The dc link ripple voltage is too high. Check for a
missing input phase.
 Check brake resistance is not less than minimum
value allowed
 check wiring and brake resistor for earth faults
 Speed feedback > 150% for 0.1 seconds
 4-20mA analog input current > 22mA could damage
the input circuit
 Braking mode set to INTERNAL (future use only).
Set to EXTERNAL and connect an External Braking
Resisitor if braking is required.
 An unknown trip - refer to Parker Hannifin
Manufacturing
 Refer to OTHER in Appendix D : TRIPS STATUS.
One or more trips have occurred with a Value greater
than 32. See the list.
