The steps for mode change are as follows:
1. Switch the drive to Servo Off by turning the SON signal of DI off.
2. Fill the mode number from the table above into the setting of the control mode in Parameter PA-
00. Refer to the description from Chapter 6.
3. After finish setting, disconnect the drive and connect the power to the drive.

Position mode
The position mode for control is used for the device requiring precise positioning, such as the
industrial machinery. The directional input of the command pulse operates the rotation angle of the
motor through the external pulse. The device accepts the pulse input up to 4Mpps. The closed-loop
system of the position focuses on the speed mode. The gain position controller and lead
compensation are added externally. Two operating modes (manual and auto) are available for the
user, just like the speed mode. The section explains the gain position controller, lead compensation
and processing of position command.
7.2.1.
Command of position mode
The command of the position mode for control (P) comes from the input pulse of the terminal block.
Three types are available for the pulse and each type is divided into positive and negative logic. The
pulse is set in Parameter PA-01. Refer to the table below:
