7-3-4 Torque Limit Function
The output terminal 019 [OTQ] over torque signal will be turned ON when the output torque monitor
[dA-17] exceeds [CE120] to [CE123].
In the case of using as an under torque signal, output will be feasible when the output terminal a/b
[NO/NC] setting [CC-11] to [CC-17] corresponding to the output terminal function [CC-01] to [CC-07]
assigned with 019 [OTQ] is switched from 00 to 01.
To calculate the motor rated torque (100%) in this function, use the following formula.
Motor rated torque = 79.58 × Motor capacity × Number of poles/Base frequency
Example: Motor rated torque = 79.58 × 5.5 (kW) × 4 (P)/50 (Hz) ≈ 35 Nm
This level is used when you detect lift excessive high load.
