Inspection of the Controller
Corrective measures
Cause
1 Faulty amplifier control board Replace servo amplifier.
Reduce voltage to within allowable
range.

4
Faulty wiring of connector CND, or
Inner regenerative circuit does not
function.
Wiring regenerative resistor correctly:
Connect regenerative resistor wires to P
and Y terminals of connector CND.
When external regenerative resistor is
used, check wiring and resistance
value. Replace Servo Amplifier if
malfunction persists.
Operating state when alarm occurred
Possible causes
Operating state
2 3 4
After main circuit power supply is turned on High High
During motor operation (alarm can be reset)
Low
During motor operation (alarm can not be
reset)
Corrective measures
1
2 Main circuit rectifier is broken Replace servo amplifier.
Check main power supply not to occur
momentary interruption or power drop.

5
Faulty internal circuit of servo
amplifier
Replace servo amplifier
Corrective measures
Power voltage of main circuit is
exceeding allowable voltage
2
Reduce load inertia to within allowable
range.
Load inertia is too large.
Alarm Code 62H (Main circuit short voltage)

High
Corrective measures
Cause
Power supply voltage is below
specified range
Set power supply to proper voltage
within specified range.
Input voltage dropped. Or
momentary interruption occurred.
3
Check main circuit voltage not to supply
around power from other to R. S. T
when main circuit OFF.
Low voltage without specification is
supplying to main circuit (R.S.T)

Confirm model number and delivery
specification of that servo amplifier.
Replace with proper amplifier for
single phase.

Take out the connector and turn ON
again. Without an alarm, check
external circuit.

Cause Corrective measures
Encoder wiring:
Incorrect wiring
Loose connector
Poor connector contact
Encoder cable is too long
Check if encoder power voltage of
motor is over 4.75V. Correct when
the voltage is below it.

Setting of encoder classification
differs from that of actual motor
encoder.
Replace with servomotor attached with
correct encoder.
Faulty amplifier control circuit Replace servo amplifier.
5 Faulty servomotor encoder
6
Parameter setting is for full close
servo system.
Set parameters for semi-close system.
Replace servo amplifier.
Replace motor and turn ON. Without
an alarm check encoder internal
circuit.
