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).
⋅ During motor operation, speed control/position control switchover and torque control/position control switchover is made when
frequency drops to the Pr. 865 Low speed detection.
CAUTION
⋅ Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.
