Technical Manual for EA350 Analog Pulse Type Servo Driver V101 If the P-OT signal is valid upon start of homing, the servo will run reversely at the speed of Pb-04 to search and stop at the target zero position. Pb-02=3 : Target zero position: First Z signal of the motor 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, and start to decelerate to stop when it receives an ORPG rising edge; then it will run reversely at the speed of Pb-04 until it finds and stops at the target zero position.
If the ORPG signal is valid upon start of homing, the servo will run reversely at the speed of Pb-05 to search the target zero position. Pb-02=4 : Target zero position: First Z pulse following the ORPG rising 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-04 to search the target zero position. 224
