3.2.3 1-10 Motor Construction
1-10 Motor Construction
Select the motor construction type.
Option:
Function:
[0] Asynchron
For asynchronous motors.
[1] PM, non salient
SPM
For permanent magnet (PM) motors.
Note that PM motors are divided into
two groups, with either surface mounted
(non-salient) or interior (salient) magnets.
NOTE!
Only available up to 30 hp [22 kW]
motor power.
NOTE!
Motor construction can either be asynchronous or
permanent magnet (PM) motor.

PM
The default control parameters for VVC
plus
PMSM control
core are optimized for HVAC applications and inertia load
in range of 50>Jl/Jm>5, were Jl is load inertia from the
application and Jm is machine inertia.
For low inertia applications Jl/Jm,<5 it is recommended
that
1-17 Voltage filter time const.
be increased with a
factor of 5
‒
10 and in some cases
1-14 Damping Gain
should also be reduced to improve performance and
stability.
For High inertia applications Jl/Jm>>50, it is recommended
that
1-15 Low Speed Filter Time Const.
,
1-16 High Speed Filter
Time Const.
and
1-14 Damping Gain
be increased to improve
performance and stability.
For high load at low speed [<30% of rated speed] it is
recommended that
1-17 Voltage filter time const.
is
increased due to non-linearity in the inverter at low speed.
