5.2.11 Torque Limiting by Analog Voltage Reference, Function 2
5 -46
This torque limiting function cannot be used at the same time as the torque feed-forward func-
tion.
Confirm the allocation of input signals when using this function. (Refer to
5.3.3 Input Circuit
Signal Allocation.
) The factory settings are shown in the following table.
/P-CL
ON and CN1-45 is low
Forward torque limit applied. Limit: Pn404 or T-REF in-
put, whichever is smaller.
OFF and CN1-45 is high
Forward torque limit not ap-
plied, i.e., normal operation.
--
/N-CL
ON and CN1-46 is low
Reverse torque limit applied.
Limit: Pn405 or T-REF in-
put, whichever is smaller.
OFF and CN1-46 is high
Reverse torque limit not ap-
plied, i.e., normal operation.

Setting
The torque limit input gain is set at user constant Pn400.
The factory setting at 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%. A
100% torque will also be used as the limit if the input torque limit value is --3 V.)

The settings of the following user constants are also valid. The torque limit will be either the
torque limit value for the analog voltage reference or the setting of Pn404/Pn405, whichever is
smaller.
