M1.1-15 Quick Stop brake torque “QSBrake”
This parameter is active only in torque mode.
This sets the strength of the when a “Quick Stop” operation is commanded by the DS402 profile. For details
please refer to [1]. The setting is a percentage of maximum motor torque. The maximum motor torque is
defined by “Maximum motor current” (adjustable in “Menu 3 “Autotuning””), assumed to be 100% of torque.
M1.1-16 Quick Stop brake ramp time “QSRamp”
In Torque Control mode this sets the time taken to ramp from null braking torque demand to full braking torque
(100% of torque when a “Quick Stop” operation is commanded by the DS402 profile. For details please refer to
[1].
Increasing the value gives a smoother but longer transition from drive to braking.
Example: if “QSbrake” is set to 10% and “QSRamp” is set to 10s the time to apply “QSbrake” torque is 1.0s.
In Speed Control mode this sets the time taken to ramp down the speed form 100% to zero (0%) or from the
active speed limit to 0% (depending on “M2-13 Variable/Constant ramp time “CnRmpTm””), when a “Quick
Stop” operation is commanded by the DS402 profile. For details please refer to [1]. Increasing the value gives
a smoother but longer transition to zero speed.
