This section describes how to set up a SynRM motor with
VVC
+
.
NOTICE
The SmartStart wizard covers the basic conguration of
SynRM motors.
Initial programming steps
To activate SynRM motor operation, select [5] Sync.
Reluctance in parameter 1-10 Motor Construction.
Programming motor data
After performing the initial programming steps, the SynRM
motor-related parameters in parameter groups 1-2* Motor
Data, 1-3* Adv. Motor Data, and 1-4* Adv. Motor Data II are
active.
Use the motor nameplate data and the motor datasheet to
program the following parameters in the order listed:
•
Parameter 1-23 Motor Frequency.
•
Parameter 1-24 Motor Current.
•
Parameter 1-25 Motor Nominal Speed.
•
Parameter 1-26 Motor Cont. Rated Torque.
Run a complete AMA using parameter 1-29 Automatic
Motor Adaptation (AMA) [1] Enable Complete AMA or enter
the following parameters manually:
•
Parameter 1-30 Stator Resistance (Rs).
•
Parameter 1-37 d-axis Inductance (Ld).
•
Parameter 1-44 d-axis Inductance Sat. (LdSat).
•
Parameter 1-45 q-axis Inductance Sat. (LqSat).
•
Parameter 1-48 Inductance Sat. Point.
Application-specic adjustments
Start the motor at nominal speed. If the application does
not run well, check the VVC
+
SynRM settings. Table 3.5
provides application-specic recommendations:
Application Settings
Low-inertia applications

/I
Motor
<5
Increase parameter 1-17 Voltage lter
time const. by factor 5–10.
Reduce parameter 1-14 Damping

Reduce parameter 1-66 Min. Current
at Low Speed (<100%).
Low-inertia applications

Increase parameter 1-14 Damping
Gain, parameter 1-15 Low Speed Filter
Time Const., and parameter 1-16 High
Speed Filter Time Const.
High load at low speed
<30% (rated speed)
Increase parameter 1-17 Voltage lter
time const.
Increase parameter 1-66 Min. Current
at Low Speed to adjust the starting
torque. 100% current provides
nominal torque as starting torque.
Working at a current level higher
than 100% for a prolonged time can
cause the motor to overheat.
Dynamic applications Increase parameter 14-41 AEO
Minimum Magnetisation for highly
dynamic applications. Adjusting
parameter 14-41 AEO Minimum
Magnetisation ensures a good
balance between energy eciency
and dynamics. Adjust
parameter 14-42 Minimum AEO
Frequency to specify the minimum
frequency at which the frequency
converter should use minimum
magnetization.
Motor sizes less than
18 kW
Avoid short ramp-down times.
Table 3.5 Recommendations for Various Applications
If the motor starts oscillating at a certain speed, increase
parameter 1-14 Damping Gain. Increase the damping gain
value in small steps. Depending on the motor, this
parameter can be set to 10–100% higher than the default
value.
