Over Torque Alarm Configuration
The torque of the motor is calculated by the drive, as a function of onverter output current and motor parameters.
The behaviour of the drive in case of detection of an excessive torque can be configured by the following parameters.
P.240 OverTorque mode
It defines the behaviour of the drive in case of overtorque detection.
P.240 = 0 Overtorque signalling during ramps and at steady state. No alarm will be generated.
P.240 = 1 Overtorque signalling only at steady state. No alarm will be generated.
P.240 = 2 Overtorque alarm and signalling during ramps and at steady state.
P.240 = 3 Overtorque alarm and signalling only at steady state.
P.241 OT curr lim thr (Overtorque current limit threshold)
Overtorque signalling threshold.
It is expressed as percentage of the Motor rated curr (P.040).
P.242 OT level fac src (Overtorque level factor source)
The overtorque level can be linearly regulated through an analog reference signal.
The regulation of this level will be performed between 0% (Analog input = 0%) and 100% of the percentage
value set by P.241 (Analog input = 100%).
This parameter selects the Analog input that has to be used for overtorque threshold modulation.
P.242 = 0 Null
P.242 = 1 Analog Inp 1 (setting through I.200…I.204)
P.242 = 2 Analog Inp 2 (setting through I.210…I.214)
P.242 = 3 Analog Inp 3 (setting through I.220…I.224)
P.243 OT signal delay (Overtorque signalling delay)
Delay time for the alarm signalling.
The overtorque alarm will be displayed with the message "Ot"
A signalling of the "overtorque" condition is available on the digital output as "Out trq>thr".
