REMARKS
⋅ Switching between speed control and torque control is always enabled independently of whether the motor is at a stop or
running or the DC injection brake operation (pre-excitation).
⋅ Speed control/position control switchover and torque control/position control switchover is made when frequency drops to the
Pr. 865 Low speed detection, and not switched during motor operation.
CAUTION
⋅ Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Please
make setting after confirming the function of each terminal.
