(2) Operation from the position board
Positioning operation using the position board is basically the same as operation for using a rotary servo
motor.
However, some parameters, home position return operation, command/status bit, and monitor No. vary
from when using a rotary servo motor. Details are as follows.
(a) Parameters
When using the direct drive system, set the parameters shown on the table below.
For other servo parameters, control parameters, and system parameters, set them as equivalent to
using a rotary servo motor.
1) Servo parameters
For details on each parameter, refer to the Servo Amplifier Instruction Manual for your servo amplifier.
