Upon completion of homing, the output terminal defined as HOME (function No. 14) immediately outputs valid signals. If servo activation is cancelled or an alarm occurs during homing, the homing function will terminate, and the HOME terminal does not output valid signals. Parameter functions: Set the short-distance movement mode upon approaching the origin: Pb-02 = 1: Target zero position: The first Z signal of the motor following the falling edge of the reverse limit switch N-OT. Deceleration point:
Reverse limit switch (N-OT) ● If the N-OT signal is invalid upon start of homing, the servo will run reversely at the speed of Pb-03, and start to decelerate to stop when it receives an N-OT rising edge; then it will run forward at the speed of Pb-04 until it finds and stops at the target zero position. ● If the N-OT signal is valid upon start of homing, the servo will run forward at the speed of Pb-05 to search and stop at the target zero position. 176 Technical Manual for EA190 Series Servo Driver V100 Caution☞ The SHOM terminal is triggered by level. If this terminal remains valid after completion of homing, homing will be executed again.
