Homing Operation (Precautions)
In initialization (i.e., operation to return to a home position) by using the host controller, if origin input (Z-phase
from the encoder) is entered before the motor has not adequately decelerated since the proximity sensor was
activated, the motor may not stop at a requested position. In order to prevent this, determine positions where the
proximity input and origin input turn on, by taking into consideration the number of pulses required for successful
deceleration. As settings of parameters “acceleration/deceleration time” have also effects on initialization,
consider both positioning and initialization when you set them.
For detailed information on initialization, refer to the operating manual for the host controller.
Example of Homing Operation
Proximity dog on .... When the proximity input turns ON, the motor will start to decelerate, and stop when a first
origin input (Z phase) is entered.
Proximity dog off .... When the proximity input turns ON, the motor will start to decelerate, and stop when a first
origin input (Z phase) is entered after the proximity input turns off.
