Parameters of the function diagram for torque limitation
p1551[0...n] Torque limit variable/fixed signal source / M_lim var/fixS_src
Sets the signal source for switching the torque limits between variable and fixed torque limit.
1 signal from BI: p1551:
A variable torque limit is effective (fixed torque limit + scaling).
0 signal from BI: p1551:
The fixed torque limit is effective.
p1552[0...n] Torque limit upper scaling without offset / M_max up offs scal
Sets the signal source for the scaling of the upper torque limit to limit the speed controller
output without considering current and power limits. A possible source is the torque preset
from the DCC diagram.
p1554[0...n] Torque limit lower scaling without offset / M_max low offsScal
Sets the signal source for the scaling of the lower torque limit to limit the speed controller
output without considering current and power limits. A possible source is the torque preset
from the DCC diagram.
