4-3 Functions When Multi-function Feedback Option Board (3G3AX-PG01) Is Used Zero Return Function •This function performs three types of zero return operations depending on the setting of zero return mode P068. When zero return is complete, the current position is cleared to zero. •You can select the zero return direction in zero return direction selection P069. •If zero return is not performed, the Inverter performs position control with the position at power-on defined as the origin. (1) The Inverter accelerates to the low- speed zero return speed according to the acceleration time setting. (2) The Inverter runs at the low-speed zero return speed.
(3) The Inverter performs positioning when the ORL signal is input. ORG terminal ORL terminal ON 4 Output frequency Functions Position Origin (1) The Inverter accelerates to the high- speed zero return speed according to the acceleration time setting. (2) The Inverter runs at the high-speed zero return speed. (3) The Inverter starts deceleration when the ORL signal is turned on. (4) The Inverter runs in reverse at the low-speed zero return speed. (5) The Inverter performs positioning when the ORL signal is turned off. ORG terminal ON ORL terminal Output frequency (P070) (1) The Inverter accelerates to the high- speed zero return speed according to the acceleration time setting.
(2) The Inverter runs at the high-speed zero return speed. (3) The Inverter starts deceleration when the ORL signal is turned on. (4) The Inverter runs in reverse at the low-speed zero return speed. (5) The Inverter starts deceleration when the ORL signal is turned off. (6) The Inverter runs forward at the low- speed zero return speed. (7) The Inverter performs positioning at the first Z-pulse position after the ORL signal is turned on.
