14. Internal Regenerative 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 regenerative resistor.
Install a counterweight.
The regenerative resistor is not
connected.
Connect correctly. Set PA2_65 at 0 or 2.
Note: The internal regenerative resistor is possibly to get hot, so do not touch it.
15. External Regenerative 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 regenerative resistor.
Install a counterweight.
Wrong wiring of external
regenerative resistor overheat
signal
Connect correctly.
The power consumption of the regenerative 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 regenerative resistor overheat signal (normally closed
contact signal) has worked (was open).
