Faults, Possible Causes and Solutions
High Bus Voltage:
A high bus voltage limit of 85 volts DC is set at the factory, any time the
voltage goes above 85V the drive immediately faults. High Bus faults can occur from the bus
power supply being too high or more likely from the bus power supply being charged up from
the motor regeneration energy. Possible solutions are slower accelerations or other methods of
storing or shunting the energy, see the Installation section. Bus Voltage can be monitored on
the Diagnostics page.
Low Bus Voltage: A low bus limit of 19 Volts DC is set at the factory, any time the voltage goes
below 19 volts the drive immediately faults. Bus Voltage can be monitored on the Diagnostics
page.
Peak Current -
A maximum current trip limit is set at the factory of 25 amps, this is in excess of
the factory set current limit of 20 amps, this fault will only occur under short circuit conditions, a
sudden crash into a hard stop from high speed or possibly in an unstable condition caused by
improper tuning parameters. Current can be monitored on the Monitored on the Status page
and the Monitor tab.
Continuous Current -
The drive continuously monitors the drive power on an I
2
t calculation and
comparing actual value to the factory limit. Once this limit is hit the drive will take the action as
setup in the System Setup page. Continuous Current can be monitored on the Monitored on the
Monitor page.
Switch Not Found-
This condition can occur in both Home and Feed Move motion types, if the
Termination Type is set to Switch (1-4) and the Current Limit for the motion is hit before the
Switch Input is sensed (Feed Move also requires the “Fault on Current Limit” box to be checked,
see the Move page.)
Following Error-
This condition occurs if the Positional Error and Time Limit are exceeded. Will
typically occur if the actuator cannot provide enough force/torque to get to desired position
either because the active current limit is set lower than needed or a hard stop or end travel has
been reached.
Board Temperature-
This condition occurs when the drive board temperature sensor is over 80
Deg C. This will occur if the actuator is continuously used above its power rating, remember de-
rating factor is required for temperatures about 25 deg C.
Actuator Temperature
- This condition occurs when the temperature sensor in the stator winding
is open indicating the temperature over 150 Deg.
Tracking Erro
r
Fault-
This is an internal fault that can only occur if the drive senses invalid
position feedback signals. A calculated Tracking Error is displayed on the Diagnostics page, 0.5
is the fault level. This condition cannot be resolved in the field, the unit must be sent to the
factory for repair.
