4-2 Function Mode •Set RUN command selection A002 to 01 (control circuit terminal block). •The following operations become possible when 20 (STA), 21 (STP), and 22 (F/R) are allocated to any of multi-function inputs 1 to 8 (C001 to C008). Allocating the STP terminal disables the FW and RV terminals. •Below are the outputs via terminal operation. 4 Functions Control Gain Switching Function •This function provides two types of gain and time constant settings for the speed control system (proportional/integral compensation). You can switch over these settings when "sensorless vector control", "0-Hz sensorless vector control", or "sensor vector control" is selected as the control method.
•If control gain switching is selected in the multi-function input selection, turning off the signal selects the gain setting of H050, H250, H051, H251, H052, or H252. Turning on the signal selects the gain setting of H070, H071, or H072. 4-86 STA ON OFF STP ON OFF F/R Forward Output frequency Reverse ON OFF ON OFF OFF ON Forward Parameter No. Function name Data Default setting Unit A044/A244 V/f characteristics selection 03: Sensorless vector 04: 0-Hz sensorless vector 05: Sensor vector 00 C001 to C008 Multi-function inputs 1 to 8 selection 26:
