4-3 Functions When Multi-function Feedback Option Board (3G3AX-PG01) Is Used •When "02" (APR2) or "03" (HAPR) is selected in P012, the Inverter performs absolute position control with reference to the absolute position from its origin. 4 Functions Sensor Vector Control (Speed Control) •To use this function, set V/f characteristics selection A044 to "05" (V2), and V2 mode selection P012 to "00" (speed control). ("Sensor vector control" can be selected for 1st control only.) •To use this function, make sure that the motor parameter settings are suitable for your motor. (Refer to "Motor Parameter Selection" (page 4-110)). Also, be sure to set the number of your encoder pulses.
•With V2 control mode selection P012, you can select four types of control modes: Speed control, Pulse train position control, Absolute position control, and High-resolution absolute position control. •Note the following before use: • Sufficient characteristics may not be obtained if you select a motor size two or more ranks lower than the maximum applicable motor size. • If the Inverter does not normally accelerate, or if overload protection is activated, check the phase order of the encoder signal.
(If phase A is advanced by 90 ° from phase B during forward run, it is judged as being normal.) When running the Inverter with V/f characteristics selection A044 set to "00" (VC), you can check the rotation direction with real frequency monitor d008. (If positive frequency is detected when the forward command is activated, or if negative frequency is detected when the reverse command is activated, the rotation direction is judged as being normal.) 4-117 Parameter No. Function name Data Default setting Unit P012 V2 control mode selection 00: ASR (speed control mode) 01: APR (pulse train position control mode) 02: APR2 (absolute position control mode) 03:
