To use this function, verify how input signals have been allocated. (Refer
to section 5.3.3 Input Circuit Signal Allocation). The following table
outlines factory default settings.
Input Signal Signal Level Description Comments
CN1-45 is at “L” level
when ON Torque is limited at the
forward run side.
Limit value: either
Pn404 or T-REF input,
whichever is smaller.
/P-CL
CN1-45 is at “H” level
when OFF
Torque is not limited at
the forward run side.
Normal Operation

CN1-46 is at “L” level
when ON Torque is limited at the
reverse run side.
Limit value: either
Pn405 or T-REF input,
whichever is smaller.
/N-CL
CN1-46 is at “H” level
when OFF
Torque is not limited at
the forward run side.
Normal operation.

„ Setting
The torque limit is set using parameter Pn400.
The default setting for Pn400 is 30. If, for example, the torque limit is ±3
V, then torque is limited to 100% of the rated torque. (A torque value
higher than 100% torque is clamped at 100%.)
