The function is provided.
(Select V/f mode)
Check the motor generation torque
using the torque detection function.
Use the free V/f setting function to turn
the motor without excess excitation.
Use the multi-step speed function.
Use the accel/decel time setting function.
Select stop procedures.
Increase torque limit value.
Apply S-curve accel/decel.
Select stop procedure according to
degree of emergency.
Increase starting torque
(with a constant-torque motor).
Drive more than one motor with
a single inverter.
Use non-excitation operating type
braking motor.
Perform 2-step speed operation.
Smooth accel/decel
Variable accel/decel time
Simple slip compensation function.
＊ Inverter capacity cannot be exceeded. Choose larger inverter capacity for the maximum torque required.
