Excitation timing output
It is turned on when the excitation state indicates the excitation
home position.
Error output
In the following cases, it is turned on.
• When overcurrent protection function is active
• When voltage-drop protection function is active (18VDC maximum)
• When the regeneration protection function is active
Regenerative voltage: 56VDC minimum/Internal temperature of
driver: 75°C minimum

1 When switching the power back again, wait at least 5sec.
∗
2 When switching the C.OFF input to “ON,” the motor excitation ends and the holding-torque is removed.

3 The duration here may vary, depending on the motor’s size, running speed and the load’s moment of inertia.
The section indicates that the photocoupler diode is emitting light.
