GX7R ASD Quick Start Guide 63
Note: The event that caused the Trip(s) must be corrected or must decrease to less than the threshold
value required to cause the trip to allow for a Reset to be recognized. In the event of multiple
active trips, the trip displayed will remain until all faults are corrected and all trips are cleared.
Overvoltage During Acceleration • Motor running during restart.
Overvoltage During Deceleration • Deceleration time is too short.
• DBR value is too high.
• DBR required (DBR setup required).
• Stall protection is disabled.
• 3-phase input voltage is out of specification.
• Input reactance required.
Overvoltage During Run • Load fluctuations.
• 3-Phase input voltage out of specification.
PG Type/Connection Error • ASD is configured to receive a signal from a shaft-mounted encoder and no signal
is being received while running.
• Disconnection at the Encoder circuit.
• Motor is stopped and is generating torque via torque limit control.
• ASD is not configured properly.
Phantom Fault • In a multiple ASD configuration a faulted ASD signals the remaining ASDs that a
fault has occurred and shuts down the non-faulted ASDs.
Position Deviation Error • Operating in the Position Control mode and the resulting position exceeds the
limits of the F631 setting.
RAM Fault • Internal RAM malfunction.
ROM Fault • Internal ROM malfunction.
Sink/Source Setting Error • Improperly positioned Sink/Source jumper on the control board or on an option
device.
• Sink/Source configuration of an option device is incorrect.
Torque Proving Fault • Lift-First Pulse Count (F743) adjustment required.
Typeform Error • Firmware information (typeform) loaded into the Gate Driver board is
inconsistent with the device in which the firmware is being used.
• The Gate Driver board has been replaced.
• The Gate Driver board is defective.
U Phase Short Circuit • Low impedance at the U lead of the ASD output.
V Phase Short Circuit • Low impedance at the V lead of the ASD output.
W Phase Short Circuit • Low impedance at the W lead of the ASD output.
