Emit a signal when torque rises or drops
• The output terminal 019 [OTQ] over torque signal
will be turned ON when the torque output value
[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.
Parameter
Output terminal [CC-01] to [CC-07]
Monitor torque limit value
• You can check the torque limit value switched by
selection on the [dA-16] torque limit monitor.
Item Parameter Data Description
Torque limit monitor [dA-16] -500.00~500.00(%)
Displays the limit value of the torque
limit function.
Output torque monitor [dA-17] -500.00~500.00(%) Displays the output torque.
Over torque level
(normal powered)
[CE120]
0.00~500.00(%)
