Chapter 1: Alarms 

 

 

CAUTION 

 

When any alarm has occurred, eliminate its cause, ensure safety, then reset the alarm, and 

restart operation. Otherwise, injury may occur.   

HYDROBAR SPRINT 555 

 

 

 

If an absolute position erase alarm (AL.25) occurred, always make home position setting again. 

Otherwise, misoperation may occur. 

 

POINT 

 

 

When any of the following alarms has occurred, always remove its cause and allow about 30 

minutes for cooling before resuming operation.  If operation is resumed by switching control circuit 
power off, then on to reset the alarm, the servo amplifier and servo motor may become faulty. 

 

Regenerative error (AL.30) 

 

Overload 1 (AL.50) 

 

Overload 2 (AL.51) 

 

The alarm can be deactivated by switching power off, then on press the "SET" button on the 

current alarm screen or by turning on the reset (RES). 

    For details, refer to Alarms and warning list. 

 

Alarm definitions and causes 

When an alarm occurs, the trouble (ALM) switches off and the dynamic brake is operated to stop the servo motor. At this time, the 
display indicates the alarm No. 

The servo motor comes to a stop. Remove the cause of the alarm in accordance with this section. The optional servo configuration 
software may be used to refer to the cause. 

Display Name 

Definition 

Cause 

Action 

1. Power supply voltage is low. 
2. There was an instantaneous 
control power failure of 60ms or 
longer. 
3. Shortage of power supply 
capacity caused the power supply 
voltage to drop at start, etc. 
4. Power was restored after the 
bus voltage had dropped to 
200VDC.  (Main circuit power 
switched on within 5s after it had 
switched off.) 

Review the power supply. 

AL.10 Undervoltage  Power 

supply 

voltage dropped. 
MR-J2S-   CP:160V 
or less 
MR-J2S-   CP1:83V 
or less 

5. Faulty parts in the servo 
amplifier  
 

Checking method 

Alarm (AL.10) occurs if power is 
switched on after disconnection of 
all cables but the control circuit 
power supply cables. 

Change the servo amplifier. 

AL.12 

Memory error 1 

RAM, memory fault 

AL.13 

Clock error 

Printed board fault 

AL.15 

Memory error 2 

EEP-ROM fault 

Faulty parts in the servo amplifier 
 

Checking method 

Alarm (any of AL.11 to 13 and 15) 
occurs if power is switched on 
after disconnection of all cables 
but the control circuit power 
supply cables. 

Change the servo amplifier. 

1. Encode connector (CN2) 
disconnected. 

Connect correctly. 

2. Encoder fault 

Change the servo motor. 

3. Encoder cable faulty  
(wire breakage or short) 

Repair or change the cable. 

AL.16 

Encoder error 1 

Communication 
error occurred 
between encoder 
and servo amplifier. 

4. Wrong combination of servo 
amplifier and servo motor 

Use correct combination.
