Name

Definition

Cause

Action

A. 17

Board error 2

CPU/parts fault

A. 18

Board error 3

Printed board fault

Faulty parts in the servo amplifier

Alarm (A. 17 or A. 18) occurs if
power is switched on after
connectors CN1A, CN1B,
CNP2, CNP3 are disconnected

Checking method

Change the servo amplifier.

A. 20

Encoder error 2 Communication

error occurred
between encoder
and servo amplifier.

Motor cable faulty
(Encoder wiring broken or shorted)

Repair or change the cable.

A. 24

Motor outout
ground fault

Ground fault
occurred at the
servo motor outputs
(U,V and W phases)
of the servo
amplififer.

Servo motor power cable insulation
deteriorated.

Change the cable.

1. Input command pulse frequency

exceeded the permissible
instantaneous speed frequency.

Set command pulses correctly.

2. Small acceleration/deceleration

time constant caused overshoot to
be large.

Increase acceleration/deceleration time
constant.

3. Servo system is instable to cause

overshoot.

1. Re-set servo gain to proper value.
2. If servo gain cannot be set to proper

value:
1) Reduce load inertia moment ratio; or
2) Reexamine acceleration/

deceleration time constant.

4. Electronic gear ratio is large

(parameters No. 3, 4)

Set correctly.

A. 31

Overspeed

Speed has exceeded
the instantaneous
permissible speed.

5. Encoder faulty.

Change the servo motor.

1. Short occurred in servo amplifier

output phases U, V and W.

Correct the wiring.

2. Transistor (IPM) of the servo

amplifier faulty.

Alarm (A. 32) occurs if power is
switched on after U, V and W
are disconnected.

Checking method

Change the servo amplifier.

3. Ground fault occurred in servo

amplifier output phases U, V and
W.

Correct the wiring.

A. 32

Overcurrent

Current that flew is
higher than the
permissible current
of the servo
amplifier.

4. External noise caused the

overcurrent detection circuit to
misoperate.

Take noise suppression measures.

A. 33

Overvoltage

Input value of
converter bus
voltage reached or
exceeded 35V.

Power supply voltage is outside the
permissible voltage range.

Change battery.
