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. 2
3. Value outside setting range has
been set in electronic gear.
Set parameters No.PA06,
PA07 correctly.

4. A negative value is set in software
limit + (parameter No.PC31, PC32).
Set positive value in
parameter No.31, PC32.
5. A positive value is set in software
limit - (Parameter No.PC33, PC34).
Set negative value in
parameter No.PC33,
PC34.
6. Opposite sign has been set in
software limit + (parameters
No.PC31, PC32). Similarly, opposite
sign has been set in software limit -
(parameters No.PC33, PC34).
Set parameters No.PC31
to PC34 correctly.

7. Opposite sign has been set in
position range output a
(parameters No. PC37, PC38).
Similarly, opposite sign has been set
in position range output address -
(parameters No.PC39, PC40).
Set parameters No.PC37
to PC40 correctly.
8. The number of write times to EEP-
ROM exceeded 100,000 due to
parameter write, etc.
Change the servo
amplifier. 1, 2
9. The torque limit switching dog
system or torque limit switching data
set system is selected for home
position return in the point table
positioning operation. (Parameter
No.PC02)
These home position return
types cannot be used. Set
parameter No.PC02
correctly. 1
10. Speed control operation was
executed with the MR-J3-D01
mounted to the servo amplifier.
When the MR-J3-D01 is
mounted to the servo
amplifier, speed control
operation cannot be
executed. Remove the MR-
J3-D01. 2
Point table setting
is wrong. Setting value is out of the setting
range. Set it correctly. 1

overheat
Main circuit device
overheat. 1. Ambient temperature of servo
amplifier is over 55 (131 ).
Check environment so that
ambient temperature is 0 to
55 (32 to 131 ).
2. Used beyond the specifications of
close mounting.
Use within the range of
specifications. (Refer to
section 2.1.)
3. The power supply was turned on and
off continuously by overloaded
status.
Check operation pattern.
4. A cooling fan or heat sink is clogged
up.
Clean the cooling fan or
heat sink.
5. Servo amplifier fault. (It occurred
after the power supply is turned on.)
Change the servo amplifier.
