<1> For p1400.4 = 0 the torque limits for the positive and negative torque direction (upwards and downwards) are compatible with MASTERDRIVES and MICROMASTER 4.
"Normal case":
If neither dynamic limits nor offsets are required, the upper torque limit is entered via p1520 and the lower via p1521 (as a negative value).
