16. INDEXER POSITIONING OPERATION
Display Name Definition Cause Action
A37 Parameter
error
Parameter setting is
wrong.
1. Servo amplifier fault caused the
parameter setting to be rewritten.
Change the servo amplifier.
2. Regenerative option not used with
servo amplifier was selected in
parameter No.PA02.
Set parameter No.PA02 correctly.
3. Value outside setting range has
been set in electronic gear.
Set parameters No.PA06, PA07 correctly.
4. The number of write times to EEP-
ROM exceeded 100,000 due to
parameter write, etc.
Change the servo amplifier.
5. The MR-J3-D01 is connected to the
servo amplifier for the indexer
positioning operation.
The MR-J3-D01 cannot be used for the
indexer positioning operation.
Point table setting is
wrong.
6. Setting value is out of the setting
range.
Set it correctly.
A45 Main circuit
device
overheat
Main circuit device
overheat.
1. Servo amplifier faulty. Change the servo amplifier.
2. The power supply was turned on and
off continuously by overloaded
status.
The drive method is reviewed.
3. Ambient temperature of servo motor
is over 55
(131 ).
Check environment so that ambient
temperature is 0 to 55 (32 to 131 ).
4. Used beyond the specifications of
close mounting.
Use within the range of specifications.
A46 Servo motor
overheat
1. Ambient temperature of servo motor
is over 40
(104 ).
Check environment so that ambient
temperature is 0 to 40 (32 to 104 ).
Servo motor
temperature rise
actuated the thermal
sensor.
2. Servo motor is overloaded. 1. Reduce load.
2. Check operation pattern.
3. Use servo motor that provides larger
output.
3. Thermal sensor in encoder is faulty. Change the servo motor.
A47 Cooling fan
alarm
Cooling fan life expiration (Refer to
section 2.5.)
Change the cooling fan of the servo
amplifier.
Foreign matter caught in the cooling
fan stopped rotation.
Remove the foreign matter.
The cooling fan of
the servo amplifier
stopped, or its
speed decreased to
or below the alarm
level.
The power supply of the cooling fan
failed.
Change the servo amplifier.
