CHAPTER 7 MAINTENANCE AND INSPECTION
Troubleshooting Method

[Cause and remedy]
Cause Remedy
The source voltage drops due to
momentary power failure or similar.
•
Check the power supply environment whether
momentary power failure is generated or not, and
improve the power supply environment.
•
Check and improve the power supply capacity and
transformer capacity.
The power is turned on or off
intentionally.
Do not turn the power on after the time specified in
PA2_68 (main power shutoff detection time) has elapsed.
(Detection fails after about 2 [s].)
DC input is under execution.
Set PA2_68 (main power shutoff detection time) at 1000 [ms].
If the power supply environment is adverse, PA2_67 (alarm detection at undervoltage) can be
applied to ignore undervoltage detection. In this case, operation can be continued with the setting
of PA2_66 (flying start at speed control) in the event of momentary power failure. Undervoltage
detection is set at about 200 [V] by the DC voltage in the servo amplifier.
15. Internal Braking Resistor Overheat
[Display]
[Description of detected alarm]
[Cause and remedy]
Cause Remedy
Excessive source voltage
(immediately after power-on)
•
Check if the source voltage is within specification limits.
•
Insert a reactor if there is a power factor improvement capacitor.
•
Increase the deceleration time.
•
Decrease the servomotor rotation speed.
•
Increase the cycle time and decrease the operation frequency.
Due to vertical transfer or
winding purpose, etc. the
regenerative power cannot be
consumed.
•
Connect an external braking resistor.
•
Install a counterweight.
The braking resistor is not
connected.
Connect correctly. Set PA2_65 at 0 or 2.
16. External Braking Resistor Overheat
[Display]
[Description of detected alarm]
[Cause and remedy]
Cause Remedy
Excessive source voltage
(immediately after power-on)
Check if the source voltage is within the specification limits.
•
Increase the deceleration time.
•
Decrease the servomotor rotation speed.
•
Increase the cycle time and decrease the operation frequency.
Due to vertical transfer or
winding purpose, etc. the
regenerative, power cannot be
consumed.
•
Connect an external braking resistor.
•
Install a counterweight.
Wrong wiring of external
braking resistor overheat
signal
Connect correctly.
The power consumption of the braking resistor built in the servo
amplifier exceeds the upper limit. (Detection is made at the
internal electronic thermal relay of the servo amplifier.)
The external braking resistor overheat signal (normally closed contact
signal) is turned off.
