Display

Error name

Definition

Cause

Action

Power was

switched on for the

first time in the

absolute position

detection system.

4. Super capacitor of the

absolute position encoder is not

charged

After leaving the alarm

occurring for a few

minutes, switch power

off, then on again.

Always make home

position setting again.

AL.30

Regenerative

alarm

Permissible

regenerative power

of the built-in

regenerative brake

resistor or

regenerative brake

option is exceeded.

1. Wrong setting of parameter

No. 0

Set correctly the

parameter no. 0

2. Built-in regenerative brake

resistor or regenerative brake

option is not connected.

Connect correctly

3. High-duty operation or

continuous regenerative

operation caused the permissible

regenerative power of the

regenerative brake option to be

exceeded.

Checking method

Call the status display and check

the regenerative load ratio.

1. Reduce the frequency

of positioning.

2. Use the regenerative

brake option of larger

capacity.

3. Reduce the load.

4. Power supply voltage is

abnormal.

MR-J2S- CP:260V or more

MR-J2S- CP1:135V or more

Review the power supply

5. Built-in regenerative brake

resistor or regenerative brake

option faulty.

Replace the amplifier

Regen transistor

fault

6. Regen transistor faulty.

Replace the amplifier

AL.31

Overspeed

Speed has

exceeded the

instantaneous

permissible speed.

1. Input command pulse

frequency exceeded the

permissible instantaneous speed

frequency.

Set correctly the pulse

frequency

2. Small acceleration

/deceleration time constant

caused overshoot to be large

Raise the time value

3. Servo system is instable to

cause overshoot.

Reset the servo gain

4. Electronic gear ratio is large

(parameters No. 4, 5)

Set correctly

5. Encoder faulty.

Replace the servo motor

AL.32

Overcurrent

Current that flew is

higher than the

permissible current

of the servo

amplifier.

1. Short occurred in servo

amplifier output phases U, V and

Correct the wiring

2. Transistor (IPM) of the servo

amplifier faulty.

Checking method

Alarm (AL.32) occurs if power is

switched on after U,V and W are

disconnected.

Replace the amplifier

3. Ground fault occurred in servo

amplifier output phases U, V and

Correct the wiring
