control terminals 12 and 27. If this is the case,
leave 5-12 Terminal 27 Digital Input at factory
default. Otherwise select No Operation. For
adjustable frequency drives with an optional
Danfoss bypass, no jumper wire is required.

3.4 PM Motor Set-up in VVCplus

CAUTION
1(1)
0-0
Use only a PM motor with fans and pumps.
*
Initial Programming Steps
1. Activate PM motor operation 1-10 Motor
Construction, select [1) PM, non-salient SPM
2. Make sure to set 0-02 Motor Speed Unit to [0] RPM
Programming motor data.
After selecting PM motor in 1-10 Motor Construction, the
PM motor-related parameters in parameter groups 1-2*,
1-3* and 1-4* are active.
The information can be found on the motor nameplate
and in the motor data sheet.
Following parameters must be programmed in the listed
order
1. 1-24 Motor Current
2. 1-26 Motor Cont. Rated Torque
3. 1-25 Motor Nominal Speed
4. 1-39 Motor Poles
5. 1-30 Stator Resistance (Rs)
1(1)
Enter line to common stator winding resistance
(Rs). If only line-line data are available, divide the
line-line value by 2 to achieve the line to
common (starpoint) value.
It is also possible to measure the value with an
ohmmeter, which will also take the resistance of
the cable into account. Divide the measured
value by 2 and enter the result.
6. 1-37 d-axis Inductance (Ld)
Enter line to common direct axis inductance of
the PM motor.
If only line-line data are available, divide the line-
line value by 2 to achieve the line-common
(starpoint) value.
It is also possible to measure the value with an
inductance meter, which will also take the
inductance of the cable into account. Divide the
measured value by 2 and enter the result.
7. 1-40 Back EMF at 1000 RPM
Enter line-to-line back EMF of PM Motor at 1,000
RPM mechanical speed (RMS value). Back EMF is
the voltage generated by a PM motor when no
drive is connected and the shaft is turned
externally. Back EMF is normally specified for
nominal motor speed or for 1000 RPM measured
between two lines. If the value is not available for
a motor speed of 1000 RPM, calculate the correct
