Parameters
• Do not set the orientation speed to a high
frequency because the deceleration behavior
becomes the positioning status within two rotations.
The overvoltage protection may cause a trip.
• Set the orientation stop position by dividing one
rotation to 4095 (0 to 4095) in the forward rotation
direction starting the reference point. (4096 division
regardless of the number of pulses for the
encoder.)
The reference point is where the pulse is input
between EZP-EZN and the stop target position is
located in a layout shown in the diagram to the left
from the viewpoint of the motor axis load. (For a
positive phase connection)
