Description
Cause
Air cooling fan of servo amplifier
stops.
Power on/off repeated in overload
state.
2045 45
Main circuit
device over
heated
Main circuit device overheat
Servo amplifier abnormal
Servo motor ambient temperature
exceeded the operating value of
40°C.
Servomotor overloaded.
2046 46
Servomotor
heated
Servo motor temperature rise
actuated the thermal protector.
Thermal protector in encoder is
faulty.
The current exceeded the
continuous output current of the
servo amplifier.
The servo system is unstable,
causing hunting.
Collision with the machine.
Servo motor miswiring servo
amplifier terminals U, V, W phase
do not mach motor terminals U, V,
W phase.

characteristic of servo amplifier.
Load ratio 300%: 2.5s or more
Load ratio 200%: 100s or more
The motor encoder fault.
Collision with the machine.
Servo motor miswiring servo
amplifier terminals U, V, W phase
don't mach motor terminals U, V, W
phase.
The servo system is unstable,
causing hunting.
