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 strongest limit is effective.
The exact correlation between the torque current and the torque is shown in the torque
monitoring (
ZFig. 174– on page 524).
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.

Bit no. Meaning
0 Indicates whether the absolute value of the effective torque (Z138.21–) is
greater or less than the set torque threshold (Z138.24–)
0: The torque is less than the torque threshold
1: Torque threshold exceeded
