Precautions for Correct Use
• Do not set the orientation speed setting to a high frequency value because the inverter decel-
erates and completes positioning within 2 rotations. Decelerating to stop causes a rapid
movement and gives a large impact on the equipment. 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.)
• When ORT terminal with the orientation control is turned OFF during motor operation, the
motor is decelerated/stopped and the output is cut off. When the motor is operated again,
turn the operation command OFF.
The reference point is where the pulse is input between EZP-EZN and the stop target posi-
tion 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)
Do not start the positioning process until the output frequency reaches the orientation speed
setting.
