1-63 Slip Compensation Time Constant
Range: Function:
0.1 s * [0.05 - 5 s] Enter the slip compensation reaction speed.
A high value results in slow reaction, and a
low value results in quick reaction. If low-
frequency resonance problems occur, use a
longer time setting.
1-64 Resonance Dampening
Range: Function:
100
%
*
[0 -
500 %]
Enter the resonance damping value. Set
parameter 1-64 Resonance Dampening and
parameter 1-65 Resonance Dampening Time
Constant to help eliminate high-frequency
resonance problems. To reduce resonance
oscillation, increase the value of
parameter 1-64 Resonance Dampening.
1-65 Resonance Dampening Time Constant
Range: Function:
0.005 s * [0.001 -
0.050 s]
Set parameter 1-64 Resonance Dampening
and parameter 1-65 Resonance Dampening
Time Constant to help eliminate high-
frequency resonance problems. Enter the
time constant that provides the best
dampening.
1-66 Min. Current at Low Speed
Range: Function:
50 % * [0 - 120 %] Applies to PM motors only. Increasing the
minimum current improves motor torque at
low speed, but also reduces
eciency.
3.2.9 1-7* Start Adjustments
Parameters for
conguring
special motor start features.
1-70 PM Start Mode
This parameter is valid since software version 2.80 and later
versions. Use this parameter to select the PM motor start mode,
which is to initialize the VVC
+
control core for previously free-
running PM motors. This parameter is active for PM motors in
VVC
+
mode only if the motor is stopped (or running at low
speed).
Option: Function:
[0] Rotor Detection The rotor detection function estimates the
electrical angle of the rotor and uses the
angle as a starting point. This option is
the standard selection for automation
frequency converter applications. If the
ying start function detects that motor is
running at low speed or is stopped, the
frequency converter can detect the rotor
position (the angle). The frequency

converter then starts the motor from that
angle.
[1]
* Parking The parking function applies DC current
across the stator winding, and rotates the
rotor to electrical zero position. This
function is typically selected for HVAC
applications. If the
ying
start function
detects that motor is running at low
speed or is stopped, the frequency
converter sends out a DC current to park
the motor at an angle. The frequency
converter then starts the motor from that
angle.
1-71 Start Delay
Range: Function:
0 s * [0 - 10
s]
This parameter enables a delay of the starting
time. The frequency converter begins with the
start function selected in parameter 1-72 Start
Function. Set the start delay time until
acceleration is to begin.
1-72 Start Function
Option: Function:
[0] DC Hold/
delay time
The motor is energized with
parameter 2-00 DC Hold/Motor Preheat
Current during start delay time.
[2]
* Coast/delay
time
The is coasted during start delay time ( o).
