HX7+ ASD Quick Start Guide 67
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.
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.
