Torque control
Operating principle
Torque-controlled stopping extends the stopping of the load. The motor is powered down on a
linear, negative torque ramp. This function is activated if there is a need to prevent the load from
being stopped abruptly.
Application
• e.g. for conveyor belts, to prevent the conveyed materials from toppling.
• Applications with a low mass inertia or a high counter-torque.
Setting via 3RW5 HMI High Feature
• Menu: "Parameters > Soft Starter > Parameter set 1 / 2 / 3 > Stopping mode settings >
Stopping mode > Torque control"
• Menu (Parameters): "Parameters > Soft Starter > Parameter set 1 / 2 / 3 > Stopping mode
settings"
• Access protection to the 3RW5 HMI High Feature is not active or has been reset.

Description
The stopping time defines the time within which the motor voltage is reduced from
line voltage to 0 V.
It may take longer for the motor to actually coast down to a standstill.
The setting "0 s" causes the motor to be shut down immediately without a down
ramp.
