9. Motor Combination Error
[Display] [Description of detected alarm]
[Cause and remedy]
Cause Remedy
The capacity and model of the servo
amplifier do not agree with those of
the servomotor. Check the capacity and model of the servomotor and
those of the servo amplifier.
10. Braking Transistor Overheat
[Display] [Description of detected alarm]
[Cause and remedy]
Cause Remedy
High source voltage
(immediately after power-on)
Check if the source voltage is within the specification limits.
Insert a reactor if there is a power factor improvement
capacitor.
Too large regeneration
power
Increase the deceleration time.
Decrease the servomotor rotation speed.
Increase the dwell and decrease the regeneration frequency.
11. Encoder Communication Error
[Display] [Description of detected alarm]
[Cause and remedy]
Cause Remedy
Interrupted encoder
communications
Broken wire or poor contact
Check cables visually and through continuity check and
correct faults.
Check for the broken wire in the encoder cable and correct.
Insert ferrite cores.
The servo amplifier and encoder communicate through high speed serial communications.
The encoder cable has a voltage amplitude of about +5 [V]. Do not route the encoder cable in a
strong magnetic or electric field. Route the encoder cable separately from the main body of the
servo amplifier, inverter, electromagnetic contactor or similar (reserve at least 100 [mm]).
The capacity and model of the servo amplifier do not agree
with those of the connected servomotor.
The regeneration handling transistor built in the servo
amplifier is overheated.
Communications with the internal encoder of the servomotor
fails.
