Cause of error
The Servomotor does not match the
Servo Driver.
Overcurrent detected, or improper radi-
ation shield temperature rise detected.
Regeneration circuit damaged due to
large amount of regenerative energy.
Regenerative energy exceeded the
regeneration resistance.
allowable range.
Servomotor rotation speed exceeded
the maximum speed.
Output torque exceeded 120% of rated
torque.
Regenerative energy exceeded the
dynamic brake resistance during
dynamic brake operation.
Inrush current exceeded the inrush
resistance during power supply inrush.
Abnormal temperature rise detected in
radiation shield.
A control circuit system error was
detected.
The Servomotor rotated in the opposite
direction from the command.
The Servomotor's electrical angle was
incorrectly detected
Encoder phase A, B, or S is discon-
nected or shorted.
Deviation counter's residual pulses
exceeded the deviation counter over-
flow level set in Pn505.
Data could not be transmitted after the
power supply was turned ON. (See
note.)
Transmission timeout error (See note.)
A warning occurs before the overload
alarm (A.70) is reached. An alarm may
be generated if the Servomotor contin-
ues to operate.
A warning occurs before the regenera-
tion overload alarm (A.32) is reached.
An alarm may be generated if the Ser-
vomotor continues to operate.
