7.9. Motor troubleshooting
Upon occurrence of error, alarms are generated by blinking the 7 segment LED of the
motor drive. In this case, take necessary actions based on the following table.
Table 7-1. Motor Troubleshooting
Alarm
Code No.
Alarms Causes Countermeasures
Control voltage is too low. Raise voltage.
Insufficient control voltage
capacity
Increase power source capacity.
11
Control Voltage
Abnormal
Damage of servo amp
circuit
Replace servo amp.
Disconnecting of
regenerative resistor.
Replace the regenerative resistance
if the resistance measured by the
tester is infinite (∞).
External regenerative
resistor inadequate.
Replace with the regenerative
resistor complying with the
specification.
12
Prevention of
Overvoltage
Damage of servo amp
circuit.
Replace servo amp.
Voltage is too low Raise the voltage.
Insufficient power source
capacity
Increase power source capacity.
Loss of one phase in the 3
phase servo amp.
Accurately connect L1, L2 and L3.
13
Main Power
Source Voltage
Abnormal
Damage of servo amp
circuit
Replace servo amp
Damage of servo amp. Replace servo amp.
Phase to phase short
circuit fault of motor cables
Correct the motor cable connection.
1 phase ground fault of
motor cable.
Correct the motor cable connection.
Motor burnt. Replace motor.
Contact fault of motor
cable.
Fix cable connection securely.
Relay for dynamic brake
has melted down.
Replace servo amp.
Motor and servo amp do
not match with each other.
Replace with the servo amp suitable
for motor.
14
Prevention of
Over Current
Pulse input arrives earlier
than servo-on.
Set the pulse input to reach 100ms
after servo-on.
Servo amp temperature is
higher than rating.
Improve the servo amp cooling
condition.
15
Overheat
Prevention
Overload of servo amp.
Decrease load by increasing the
capacities of servo amp and motor.
