Functions
•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.
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.
•If control gain switching is not selected in multi-function inputs 1 to 8 (C001 to C008), the gain
setting conforms to the status in which the signal is turned off.
