Technical Manual for EA350 Analog Pulse Type Servo Driver V101 8.6 P1-xx Position control parameters Parameter functions: Select a position command source P1-00=0: External pulse command (pt) Position pulses are sourced from external input; the frequency of external pulses determines the motor speed. P1-00=1: Multi-segment position command (Pr) Position commands are sourced from the multi-segment position command set by group P9. See detailed description of group P9. Parameter functions: Select a mode of external pulse commands. Note that forward rotation refers to clockwise or anticlockwise rotation of the motor shaft, which is determined by P0-01.
The view is from the shaft end by default, and the forward rotation is counterclockwise. Parameter functions: Set the count of command pulses required for one revolution of the motor (360°). The command pulses may come from an external pulse command or from a multi-segment position command. When this parameter is set to 0, it means this parameter is inactive; in this case, the relation between the count of command pulses and revolutions of the motor is set by using the electronic gear ratio.
