ON: Rotates the motor using the position command
pulse multiplied by the value set in Pn217 (command
pulse factor). (When Pn218.0 = 1)

Note 1. Function allocations for pin 40 to 46 sequence inputs can be set by means of user parameters
Pn50A to Pn50D. In this table, the numbers enclosed in brackets indicate the default pin num-
bers (allocations). The allocations vary depending on the control mode.
Note 2. This I/O signal is supported by Servo Drivers with software version “r.0037.”
