Servo Alarm
Cause and Remedy
Bus cable or printed board is faulty
(Cause 1) Bus cable is disconnected.
(Remedy) Connect the connector of the bus cable.
(Cause 2) Bus cable fault.
(Remedy) Change the cable.
(Cause 3) Printed board is faulty.
(Remedy) Change the servo amplifier.
36 Transfer error
(Cause 4) Termination connector disconnected
(Remedy) Connect termination connector.
Parameter setting is wrong.
(Cause 1) Servo amplifier fault caused the parameter setting to
be rewritten.
(Remedy) Change the servo amplifier.
37 Parameter error
(Cause 2) There is a parameter whose value was set to outside
the setting range by the controller.
(Remedy) Change the parameter value to within the setting
range.

Servo Alarm
Cause and Remedy
A linear servo control error was detected.
(Cause 1) The mounting direction of the linear scale is not
matching.
(Remedy) Check the mounting direction of the linear scale.
Review the settings (Linear Scale Electronic
Gears) of Parameter Nos. 65 and 66.
Check the linear scale control error detection level
+F67.
(Cause 2) The motor worked with Servo ON.
(Remedy) Confirm that the motor has stopped and set
"Servo ON" again.
(Cause 3) Initial Magnetic Pole Detection Not Executed
(Remedy) Execute the initial magnetic pole detection.
42 Linear Servo
Control Error
Detection
(Cause 4) The resolution of the linear scale signal is different from
the specified one.
(Remedy) Review the settings (Linear Scale Electronic
Gears) of Parameter Nos. 65 and 66.
Check how the linear scale is mounted.
Main circuit device overheat
(Cause 1) Servo amplifier faulty.
(Remedy) Change the servo amplifier.
(Cause 2) The power supply was turned on and off
continuously by overloaded status.
(Remedy) Review the drive method.
45 Main circuit
device overheat
(Cause 3) Air cooling fan of servo amplifier stops.
(Remedy 1) Change the servo amplifier or cooling fan.
(Remedy 2) Reduce ambient temperature.

Servo Alarm
Cause and Remedy
Servo motor temperature rise actuated the thermal
protector.
(Cause 1) Ambient temperature of servo motor is over 40°C.
(Remedy) Review environment so that ambient temperature
is 0 to 40°C.
(Cause 2) Servo motor is overloaded.
(Remedy 1) Reduce load.
(Remedy 2) Review operation pattern.
(Remedy 3) Use servo motor that provides larger output.
46 Servo motor
overheat
(Cause 3) Thermal protector in encoder is faulty.
(Remedy) Change servo motor.
Load exceeded overload protection characteristics of servo
amplifier.
Load Factor 300%: 2.5 s or more
Load Factor 200%: 100 s or more
(Cause 1) Servo amplifier is used in excess of its continuous
output current.
(Remedy 1) Reduce load.
(Remedy 2) Review operation pattern.
(Remedy 3) Use servo motor that provides larger output.
50 Overload 1
(Cause 2) Servo system is instable and hunting.
(Remedy 1) Repeat acceleration/deceleration to execute auto
tuning.
(Remedy 2) Change auto tuning response setting.
(Remedy 3) Set auto tuning to OFF and make gain
adjustment manually.
