Torque limits

Details
The positive and negative torque limit can be set independently of each other. The torque
limit is to be configured to the maximum torque.
Display of the current positive torque limit in 0x2949:004.
•
Display of the current negative torque limit in 0x2949:003.
•
The torque limits are also active in the "Velocity Mode" for the SC-ASM control mode.
Regardless of the setting in 0x2949:004 and 0x2949:004, the maximum torque
does not exceed the value configured in 40x6072.
The setting is made in percent with reference to the rated motor torque set in 0x6076.
