Setting the parameters that establish the exact type of motor used is important if the drive is to run
correctly. These parameters are:
Name Description
PRC_MOT_I_NOM P61 - Rated motor current ( I NOM MOT)
MOT_V_NOM P62 - Rated motor voltage
MOT_F_NOM P63 - Rated motor frequency
MOT_POLE_NUM P67 - Number of motor poles
These parameters are fundamental in that they are the basis of all the motor operating
characteristics: frequency, speed, voltage, current, torque and thermal protection.
P62 and P63 can be read directly on the motor rating plate and P61 can be calculated with the
following formula:
P61 = (Inom_motor *100.0))/(Inom_drive)
Example: Drive: OPEN 22
Inom_drive = 22A overload 200%
Motor: MEC series, Vn = 380V, f = 50Hz, Inom_motore = 20A,
P61 = (20*100)/22 = 90.9%
P62 = 380.0
P63 = 50.0
There are also parameters that establish the maximum values for voltage, thermal current and
operating speed:
Name Description
PRC_MOT_V_MAX P64 - Max. operating voltage
MOT_SPD_MAX P65 - Max. operating speed (n MAX)
PRC_MOT_I_THERM P70 - Motor thermal current
MOT_TF_THERM P71 - Motor thermal time constant
These important parameters must be specified alongside the exact characteristics of the feedback
sensor used. Once the sensor has been established, the “
Sensor and motor pole tests ”
can be
carried out (enabled with C41) which will confirm that the parameters have been set correctly.
