When the torque setpoint reaches torque limit, the torque is limited to the value selected by
TLIM1/TLIM2.
Note
Control mode
The above four sources are valid in the PTI mode, the IPos mode and the S mode. You can
switch among them when the servo drive is runni
ng.
Note
When the motor torque exceeds the torque limit, fault F52911/F52912 appears. The fault
indicates the motor torque exceeds the torque limitation of the selected group which is
determined by TLM1 and TLM2.
Refer to "DIs (Page 123)" for more information about the digital input signals TLIM1 and
TLIM2.
Overall torque limit
Besides the above four sources, an overall torque limit is also available for
all
control modes.
The overall torque limit takes effect when an quick stop (OFF3) happens. In this case, the
servo drive brakes with a maximum torque.
