Parameter error
Parameter setting is
wrong.
1. Servo amplifier fault caused the
parameter setting to be rewritten.
Change the servo
amplifier
2. There is a parameter whose value
was set to outside the setting range by
the controller
Change the
parameter value to
within the setting
range

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.
Check control
mode
3. Air cooling fan of servo amplifier
stops.
1. Change the
servo amplifier or
cooling fan
2. Observe max.
permitted ambient
temperature
46
Servo motor
overheat
Servo motor
temperature rise
actuated the thermal
protector.
1. Ambient temperature of servomotor
is over 40°C.
When planning the
system ensure that
the ambient
temperature is
always between 0
and 40 °C.
2. Servo motor is overloaded.
1. Reduce load
2. Extended cycle
time
3. Use servo motor
that provide larger
output
3. Thermal protector in encoder is
faulty.
Change servo
motor

Overload 1
Overload of servo
amplifier

1. The output current exceeds the
rated current continuously.
1. Reduce load
2. Extended cycle
time
3. Use servo motor
that provide larger
output
2. Servo system is unstable.
1. Repeat
acceleration/
deceleration to
execute auto tuning
2. Change auto
tuning response
setting
3. Set auto tuning
to OFF and make
adjustment
manually
3. Mechanical overload
1. Ensure that
mechanical
components run
smoothly
2. Install limit
switches
4. Wrong connection of servo motor.
Servo amplifiers output terminals U, V,
W do not match servo motors input
terminals U, V, W.
Connect correctly
5. Encoder error
Change the servo
motor
