Motor data
For optimum torque control during the stopping procedure, enter the motor data of the motor
connected to the soft starter in the selected parameter
set using the "Motor parameters"
menu item. The "Motor parameters" menu item can be found at the following path:
"Parameters > Soft Starter > Motor parameters".
Stopping time The length of 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 parameter value "0" causes the motor to be shut down
immediately without a down ramp.
• Factory setting: 10 s
• Setting range: 0 ... 360 s
• Increment: 0.1 s
Stopping torque The motor torque is "controlled" until the stopping torque is
reached and then switched off.
• Factory setting: 10 %
• Setting range: 10 ... 100 %
• Increment: 5%
