Alternative stopping time Depending on the alternative stopping mode set, observe the description of the param‐
eter "Stopping time" in the relevant chapter:
• Voltage ramp (Page 149)
• Torque control (Page 150)
• Pump stopping mode (Page 152)
• DC braking (Page 154)
• Dynamic DC braking (Page 157)
• Reversing DC braking (Page 160)
• Factory setting: 10 s
• Setting range: 0 ... 360 s
• In steps of: 0.1 s
Alternative stopping torque Depending on the alternative stopping mode set, observe the description of the param‐
eter "Stopping torque" in the relevant chapter:
• Torque control (Page 150)
• Pump stopping mode (Page 152)
The motor torque is "controlled" until the alternative stopping torque is reached and then
switched o. The rated torque of the motor is used as the reference value.
• Factory setting: 10%
• Setting range: 10 ... 100%
• In steps of: 5%
Alternative dynamic braking torque Depending on the alternative stopping mode set, observe the description of the param‐
eter "Dynamic braking torque" in the relevant chapter:
• Dynamic DC braking (Page 157)
• Reversing DC braking (Page 160)
• Factory setting: 50%
• Setting range: 20 ... 100%
• In steps of: 5%
