Overall torque limit
Besides the above two sources, an overall torque limit is also available. The overall torque
limit takes effect when a quick stop (OFF3) happens. In this case, the servo drive brakes
with a maximum torque.
You can configure the overall torque limit by setting the following parameters:
Parame-
p1520
p1521
Internal torque limit
Select an internal torque limit by setting the following parameters:
Parameter
p29050[0]
p29050[1]
p29051[0]
p29051[1]
The following diagram shows how the internal torque limit functions:
Torque limit reached (TLR)
When the generated torque has nearly (internal hysteresis) reached the value of the positive
torque limit or negative torque limit, the signal TLR is output.
