User Manual Chapter 7 - Parameters Description 99
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 a 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% (setting the inputs at 0V - 0mA - 4mA) and 100% of
the percentage value setted with P.241 (+/- 10V - 20mA).
This parameter selects the source from where this function is provided and controlled.
P.242 = 0 OFF
P.242 = 1 Analog Inp 1 (setting through I.200I.204)
P.242 = 2 Analog Inp 2 (setting through I.210I.214)
P.242 = 3 Analog Inp 3 (setting through I.220I.224)
P.243 OT signal delay (Overtorque signalling delay)
Delay time for the alarm signalling.
The alarm will be displayed with the message "Ot"
A signalling of the "overtorque" condition is available on the digital output as "Out trq>thr".

Motor Overload Configuration
P.260 Motor OL prot en (Motor overload protection enabling)
Enabling of the motor thermal protection.
The control is performed as an I2t, calculated on the basis of the setting of
Motor rated curr (P.040) and Motor thermal K (P.045).
An overload of the motor, will cause the intervention of the alarm "Motor overload".
The parameter d.052 (menu DISPLAY), is the monitoring of the motor overload level.
A value of 100% represent the threshold for the alarm.
The alarm will be displayed with the message "OLM"
A signalling of the "overcurrent" condition is available on the digital output as "Alarm state".
