Note 1. It is different according to the operation status.
2. The dynamic brake does not operate while the control circuit power supply is cut.
(2) Supplementary explanation
(a) Overcurrent/Overload 1/Overload 2
Driving the servo motor by cycling the control circuit power repeatedly to restart without removing the
cause of an occurring alarm of Overcurrent (32. )/Overload 1 (50. )/Overload 2 (51. ) will raise
temperature. Doing so may result in a malfunction of the servo amplifier or servo motor. Remove its
cause and allow about 30 minutes for cooling before resuming the operation.
(b) Regenerative error
Driving the servo motor by cycling the control circuit power repeatedly to restart without removing the
cause of an occurring Regenerative error (30. ) will raise the temperature of regenerative resistor.
Doing so may result in a malfunction of the servo amplifier or servo motor.
(c) Instantaneous power failure
Undervoltage (10. ) occurs on the following conditions.
A power failure occurred for 15 ms at the control circuit power supply and recovered.
Bus voltage dropped to 24VDC, 15VDC/48VDC, 35VDC on the servo-on status.
