Overtorque/Undertorque Function

Overtorque/Undertorque Function Settings
Use this function to detect that the estimated motor output torque value exceeded the set level and
output the overtorque signal.
• To enable detection of the overtorque state, allocated “46: OTQ (Over/under torque signal) (NO con-
tact)” to Output Terminal [DO1] Function Selection (E20), Output Terminal [DO2] Function Selection
(E21) or Output Terminal [ROA, ROB] Function Selection (E27). Detection of the undertorque state
also can be enabled by allocating “1046: OTQ (Over/under torque signal) (NC contact).”
• The overtorque/undertorque ON signal is output when the torque value calculated by the inverter or
the torque command value is at the set level of torque detection (operation level) or higher, and con-
tinues for the set time of torque command detection (timer time) or longer. The overtorque/undertor-
que signal is turned OFF when the torque calculation value becomes “operation level - 5% of the
motor rated torque or lower.”
• The operation level can be set separately to each of the four quadrants, and the state at accelera-
tion/deceleration and constant speed also can be selected.
• For calculating the overtorque and undertorque levels in this function, the motor rated torque is tak-
en to be 100%.
• Use this function to detect the brake release signal of an elevator, or if the load applied to the load
machine is abnormally high.
