Description
Stopping time
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.
• Factory setting: 10 s
• Setting range: 0 ... 360 s
• In steps of: 0.1 s

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.
