Value Description
2 Permanent magnet synchronous motor
1 VECTOR: SPEED
2 VECTOR:TORQ
Note: Scalar control mode (3) can also be selected, but it is not
recommended because in the scalar control mode the
permanent magnet synchronous motor may get unstable and
damage either the process, the motor or the drive.
Note: If the back emf voltage of the motor is not available, set
the rated value here and run the ID run. If the voltage is given as
a proportional value, such as 103 V/1000 rpm in a 3000 rpm
motor, set 309 V here. Sometimes the value is given as the
peak value. In this case, divide the value by the square root of 2
(1.41).
Note: It is recommended to use the back emf voltage. If it is not
used, a full ID run must be performed.
Rated current of the motor. Do not use the peak value.
Rated electrical frequency of the motor. If the frequency is not
given in the motor rating plate, it can be calculated using the
following formula:
frequency [Hz] = speed [rpm] x (number of pole pairs) / 60
Rated mechanical speed of the motor. If it is not given, it can be
calculated using the following formula:
speed [rpm] = frequency [Hz] x 60 / (number of pole pairs)
Motor nominal power. If it is not given, it can be calculated using
the following formula:
Power [kW] = Rated torque [Nm] x 2 x pi x rated speed [rpm] /
60000
RAMP It is recommended to use ramp stop with a PMSM.
