4.8.9.3 Application-specific torque limitation
The torque limitation is parameterized via the following objects.
The torque limits are indicated in % referring to the rated motor torque. The resolu-
tion is 0.1%.
absolute torque
max torque
Max. torque (applies in all quadrants)
torque limit mot for
positive torque limit value
Torque limit mot., positive speed
torque limit mot rev
negative torque limit value
Torque limit mot., negative speed
-1: Value is accepted from cs13
Torque limit gen., positive speed
-1: Value is accepted from cs13
-2: Value is accepted from cs14
Torque limit gen., negative speed
-1: Value is accepted from cs15
-2: Value is accepted from cs13
The following behavior is described in the CiA402 profile: positive torque
limit value is valid for mot. for and gen. rev
negative torque limit value is valid for mot. rev and gen. for
To achieve this behavior, the following setting must be made: cs16 = -2 (cs16
= cs13) ; cs15 = -2 (cs15 = cs14)
