Fault Display And Corrective Actions At Auto-Tuning - Magnetek Impulse G+ series 4 Instruction Manual

Fault Display and Corrective Actions at Auto-Tuning

The following are fault displays and corrective actions at auto-tuning. If any of the following faults are
found, the digital operator displays that fault contents; the motor coasts to stop if it is under
operation. Fault contact output or minor fault contact output does not operate.

Table 6-5: Fault Display and Corrective Actions
Fault or Indicator Name/Description
Motor Data Fault. Motor data input fault for
auto-tuning. Relationship between motor
output and motor rated current fault.
Relationship between input motor rated
current and set no-load current fault (at vector
control method and line-to-line resistance
tuning.)
Alarm. The minor fault is detected during
auto-tuning.
STOP Key Input. The stop key is pressed
during auto-tuning.
Line to Line Resistance Fault. Auto-tuning
is not completed within the expected time.
The auto-tuning is outside the parameter
setting.
No-load Current Fault. Auto-tuning is not
completed within the expected time. The
auto-tuning is outside the parameter setting.
Rated Slip Fault. Auto-tuning is not
completed within the expected time. The
auto-tuning is outside the parameter setting.
Acceleration Fault. The motor did not
accelerate at the expected time.
Motor Direction Error. The encoder signal
lines are not properly connected to the drive;
the motor direction and PG direction are
opposite; or the load pulled the motor in the
opposite direction of the speed reference and
the torque exceeded 100%.
Motor Speed Fault (Rotation type tuning
only).
The motor speed was over 100% at auto-
tuning (flux vector control without PG only).
Current Detection Fault. Current exceeded
the motor rated current.
Leakage Inductance Fault. Auto-tuning did
not finish within the set time.

Corrective Action
• Check input data.
• Check inverter and motor capacity
• Check motor rated current and no-load
current.
• Check input data.
• Check wirings
• Check load.
• Check input data.
• Check motor wiring.
• If a motor and a load are connected,
disconnect the motor from machinery
system.
• Increase B05-01 (acceleration time).
• If C07-01 and C07-02 (torque limit value)
are decreased, increase values.
• If a motor and a load are connected,
separate the motor from the load.
• Check and correct wiring to the PG
encoder.
• Check the motor speed monitor U01-05
while manually turning the motor forward. If
the sign displayed is negative, change the
setting of parameter F01-02.
• Uncouple the motor from the load and
restart Auto-Tuning.
• Increase B05-01 (acceleration time).
• If a motor and a load are connected,
separate the motor from the load.
• Release brake.
• Check for open motor lead.
• Check the T1 parameters.
• Check motor wiring.
