When torque limitation is activated in Application function menu, torque limit can be set in two ways. (1) by parameter ( fix value). (2) By analog input .
If both types are enabled, the lowest value will be taken into account.
Parameter tLIN is to define motoring torque limit. Meaning this is the value when drive operation is in Motor mode.
Yes, 100% of setting to tLIN refers to the 100% of motor nominal torque.
