<1> For p1400.4 = 0 the torque limits for the positive and negative torque direction (upwards and downwards) are compatible to MASTERDRIVES and MICROMASTER 4.
"Normal case": If neither dynamic limits nor offset are required, the upper torque limit is entered via p1520 and the lower (as negative value) via p1521.
<2> Danger!
Negative values at or positive values at
A
<3> The limiters ensure that the limits do not mutually "overtake" one another.
<4> For the manufacturer-specific PROFIBUS telegrams 102 ... 106 r1543 is switched-in here [5610.4].
