Torque Limit Change during Brake Control
In order to reduce the torque during motor deceleration at emergency stop the function
"Torque limit change during brake control" can be used.
Brake Control outputs the VCMD=0 and Torque Limit 70% (default).
Quick Stop Function outputs VCMD=0 and Torque Limit 100% (depends on N2060).
If the torque limit is set by N2060 then the maximum torque is always limited, also during normal
acceleration and deceleration.
With the Torque Limit Change at Brake Control the torque limit is only applied during E-Stop.
• Parameters:
N2273 #7 = 1 Enable "Torque limit change during brake control"
N2375 Torque limit multiplier in %
Range: 0-100 (100% means maximum torque)
Setting of 0 means 70% of maximum torque.
• Applicable Servo Software
90B0/17(Q) or subsequent version
90B6/01(A) or subsequent version
90D0/01(A) or subsequent version
90E0/01(A) or subsequent version
• Note:
o This function cannot be used together with Quick Stop function (N2017 #0=1).
o The internal torque limit change is applied to Brake Control only after E-Stop. But the
torque limit by PMC window takes the first priority. So even if in the brake control mode,
the torque limit by PMC window should be effective.
