Danfoss VLT AutomationDrive FC 361 Programming Guide

1-06 Clockwise Direction
Option: Function:
NOTICE
This parameter cannot be
adjusted while the motor is
running.
This parameter denes the term
clockwise corresponding to the LCP
direction arrow. Used for easy
change of direction of shaft
rotation without swapping motor
wires.
[0] * Normal The motor shaft turns in clockwise
direction when the frequency
converter is connected U⇒U, V⇒V,
and W⇒W to the motor.
[1] Inverse Motor shaft turns in counter-
clockwise direction when the
frequency converter is connected
U⇒U, V⇒V, and W⇒W to the motor.
4.2.2 1-1* Special Settings
NOTICE
The parameters within this parameter group cannot be
adjusted while the motor is running.
1-10 Motor Construction
Option: Function:
Select the motor design type.
[0] * Asynchron Use for asynchronous motors.
[1] PM, non
salient SPM
Use for salient or non-salient PM
motors.
PM motors are divided into 2
groups, with either surface-
mounted (SPM)/non-salient
magnets or interior-mounted (IPM)/
salient magnets.
1-14 Damping Gain
Range: Function:
140 %* [0 - 250 %] The damping gain stabilizes the PM
machine to run smoothly and with
stability. The value of damping gain
controls the dynamic performance
of the PM machine. High damping
gain gives high dynamic
performance and low damping gain
gives low dynamic performance.
The dynamic performance is related
to the machine data and load type.
1-14 Damping Gain
Range: Function:
If the damping gain is too high or
low, the control becomes unstable.
1-15 Low Speed Filter Time Const.
Range: Function:
Size
related*
[0.01 - 20 s] This time constant is used below
10% rated speed. Obtain quick
control through a short damping
time constant. However, if this value
is too short, the control becomes
unstable.
1-16 High Speed Filter Time Const.
Range: Function:
Size
related*
[0.01 - 20 s] This time constant is used above
10% rated speed. Obtain quick
control through a short damping
time constant. However, if this value
is too short, the control becomes
unstable.
1-17 Voltage lter time const.
Range: Function:
Size
related*
[0.001 - 2 s] Reduces the inuence of high
frequency ripple and system
resonance in the calculation of
supply voltage. Without this lter,
the ripples in the currents can
distort the calculated voltage and
aect the stability of the system.
1-18 Min. Current at No Load
Range: Function:
0 %* [0 - 50 %] Adjust this parameter to achieve a
smoother motor operation.
