Technical Manual for EA350 Analog Pulse Type Servo Driver V101 If the ORPG signal is invalid upon start of homing, the servo will run reversely at the speed of Pb-04 to search the target zero position. Pb-02 = 7 : Target zero position: First Z signal following the ORPG falling edge Deceleration point: Origin switch (ORPG) If the ORPG signal is invalid upon start of homing, the servo will run forward at the speed of Pb-03: ◼ If no signal of the forward limit switch P-OT is received, the servo will decelerate to stop when it receives an ORPG rising edge signal; then it will run reversely at the speed of Pb-04 to search the target zero position.
If a signal of the forward limit switch P-OT is received, the servo will automatically run in the reverse direction at the speed of Pb-03; when it receives an ORPG rising edge signal, it will start to decelerate to the speed of Pb-04, and then keep running to and stop at the target zero position. 226
