Commissioning
1. Activate travel to fixed end stop
Set p1545 = "1"
2. Set the desired torque limit
Example:
p1400.4 = "0" ----> upper or lower torque limit
p1520 = 100 Nm ----> effective in upper positive torque direction
p1521 = --1500 Nm ----> Effective in lower negative torque direction
3. Run motor to fixed stop
The motor runs at the set torque until it reaches the stop and continues to work
against the stop until the torque limit has been reached, this status being
indicated in status bit r1407.7 "Torque limit reached".
