Setting the torque limit level
Limit the output torque not to exceed the specified value.
The torque limit level can be set in a range of 0% to 400%. The TL signal can be used to switch between two types of torque
limit.
The torque limit level can be selected by setting it with a parameter, or by using the analog input terminal (terminal 4). Also, the
torque limit levels of forward rotation (power driving/regenerative driving) and reverse rotation (power driving/regenerative
driving) can be set individually.
