3. Alarms and Remedies
Alarm No.
14 Overvoltage error
Symptom
and
Possible Cause
The primary circuit voltage of the control component has exceeded the amplifier circuit limits.
Remedy
If the alarm occurs only during deceleration
By using the Setup Panel or "Servo Studio", check the regeneration status, which tells you
if a regenerative resistor is necessary. If necessary, install a regenerative resistor.
Check the motion patterns of commands.
Use a command filter and gradually decrease the speed.
If the alarm occurs regardless of deceleration
Verify that the primary circuit power voltage is within specification.
Check for voltage changes while the whole system is operating.
Reset Method
Alarm No.
15 Power supply error (primary circuit power)
Symptom
and
Possible Cause
The primary circuit voltage is abnormally high or low.
The primary circuit power was not supplied.
The primary circuit power was not within the input range.
The primary power voltage fluctuated and exceeded the rated range.
SVON signal was input without primary circuit power supply.
Anomaly of the regenerative control circuit operating time lasted longer than a specific
amount of time.
Regeneration ON status lasted.
Remedy
If the alarm occurred between servo on and operation startup
Verify that the primary circuit power is connected to the amplifier.
Check the primary circuit power voltage.
Check the timing of primary circuit power input and SVON signal input.
If the alarm occurred during motor operation
Check for no voltage fluctuations due to the whole system operation.
Provide enough power supply so that the system experiences no voltage fluctuations.
If the alarm occurs during deceleration
Check the regenerative voltage warning spinal on the Setup Panel or "Servo Studio".
If a regenerative voltage warning occurs, install a regenerative resistor.
Check the motion patterns directed by commands.
Gradually decrease speeds by using a command smoothing filter.
Reset Method
RESET Signal
① Eliminate the cause.
② input RESET signal to the RESET terminal
on the connector CN1.
Control-power cycle
① Eliminate the cause.
② Cycle control-power.
CLEAR Encoder
① Eliminate the cause.
② Execute CLEAR Encoder
③ Cycle control-power.
After power cycle, perform Homing.
