H18
Torque control (Mode selection)
Related function codes: F40, F41 (Torque limit 1-1, 1-2)
d32, d33 (Speed limits / Over speed level 1 and 2)
When vector control (sensorless, with speed sensor) is selected, the inverter can control the motor-generating
torque according to a torque command sent from external sources. Under torque control, the speed is automatically
calculated based on the torque command, and output from the inverter.

Fig. 5.3-29 Block diagram of torque control
The following functions are disabled during torque control.
Speed control based on speed command, auto energy-saving operation, jogging operation, switching to commercial
power supply, DC braking, PID control, pre-excitation, servo lock, droop, pattern operation, overload prevention
control, anti-regenerative control, brake signals, position control
 Torque control (Operation selection) (H18)
H18 specifies whether to enable or disable the torque control. Enabling the torque control offers two choices: with
torque current command and with torque command.
