5-5 Settings Relating to Control Method
The following explains the control-related settings such as the control method and torque
boost.
Control Method (V/f Characteristics)
You can set V/f characteristics (output voltage/output frequency).
Switch between Control Methods 1/2 (V/f characteristics) using the SET terminal which is a
multi-function input terminal to which Motor 2 Control (08: SET) is allocated.
Constant Torque Characteristics (VC)
Output voltage is proportional to output frequency.
While the output voltage is proportional from 0 Hz to base frequency, the output voltage is
constant from base to maximum frequency regardless of the frequency.
