The exact correlation between the torque current and the torque is shown in the torque
monitoring (
ZFig. 133– on page 505).
138.22 Torque limit symmetric
The same limit acts in both directions. The torque limit is carried out by limiting the torque
current set value. The accordant limit at the torque-generating current l
sqM limit
is calcu-
lated as follows:

Furthermore, other settable torque limits are available that result from the setting of the
torque current limit (
Z138.2–, Z138.3–, Z138.14–, Z138.15–). Furthermore, other
torque current limits are available Z138.18–, Z138.30–, Z114.5– and Z114.6–, that limit
the torque due to a breakdown torque or an excessive U

actual value. The torque can
be disabled due to a power failure refer to
Z138.10– bit 1).
The strongest limit is effective.
The exact correlation between the torque current and the torque is shown in the torque
monitoring (

138.24 Indication threshold torque
If the absolute value of the effective torque (Z138.21–) exceeds the value of the torque
threshold, bit 0 in parameter Status current limitation (Z138.25–) is set.
