With a Quick Stop, the ongoing movement is stopped.
A Quick Stop can be triggered by a detected error of error classes 1 or 2 or via a fieldbus command.
The movement can be stopped with 2 different deceleration types.
oDeceleration via deceleration ramp
oDeceleration via torque ramp
In addition, you can set the operating state to switch to after the deceleration.
oTransition to operating state 9 Fault
oTransition to operating state 7 Quick Stop Active
Setting the Type of Deceleration
The parameter LIM_QStopReact lets you set the type of deceleration.

Quick Stop option code. -2 / Torque ramp (Fault): Use torque ramp and transit to operating state 9 Fault -1 / Deceleration Ramp (Fault): Use deceleration ramp and transit to operating state 9 Fault 6 / Deceleration ramp (Quick Stop): Use deceleration ramp and remain in operating state 7 Quick Stop 7 / Torque ramp (Quick Stop): Use torque ramp and remain in operating state 7 Quick Stop Type of deceleration for Quick Stop.
Setting of deceleration ramp with parameter RAMPquickstop. Setting of torque ramp with parameter LIM_I_maxQSTP.
If a deceleration ramp is already active, the parameter cannot be written. Type: Signed decimal - 2 bytes Write access via Sercos: CP2, CP3, CP4 Modified settings become effective immediately. |

Current for Quick Stop. This value is only limited by the minimum/maximum value range (no limitation of this value by motor/power stage).
In the case of a Quick Stop, the current limit (_Imax_act) is one of the following values (whichever is lowest): - LIM_I_maxQSTP - _M_I_max - _PS_I_max
Further current limitations caused by I2t monitoring are also taken into account during a Quick Stop.
Default: _PS_I_max at 8 kHz PWM frequency and 230/480 V mains voltage Type: Unsigned decimal - 2 bytes Write access via Sercos: CP2, CP3, CP4 In increments of 0.01 Arms. Modified settings become effective immediately. |
