1-10 Motor Construction
Select the motor construction type.
Option: Function:
[0] Asynchron For asynchronous motors.
[1] PM, non salient For permanent magnet (PM) motors.
SPM 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.
3.2.4 1-14 - 1-17 VVC plus
The default control parameters for VVC
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. and1-14 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.

Range:
120 % [ 0 - 250 %]
