30-19 Wobble Delta Freq. Scaled
Range:
Function:
0 Hz
*
[0 - 1000 Hz] Readout parameter. View the actual
wobble delta frequency after scaling has
been applied.

Range:
Function:
Size related
*
[0 - 60 s]
NOTICE

302 only.
High starting torque time for PM motor
in flux control principle without
feedback.
30-21 High Starting Torque Current [%]
Range:
Function:

*
[ 0 -
200.0 %]
NOTICE
This parameter is available for
FC 302 only.
High starting torque current for PM
motor in VVC
+
and flux mode
without feedback.
30-22 Locked Rotor Protection
Option: Function:
NOTICE
This parameter is available for FC 302 only.
Available for PM motors only, in flux sensorless mode
and VVC
+
open-loop mode.
[0] Off
[1] On Protects the motor from the locked rotor condition. The
control algorithm detects a possible locked rotor
condition in the motor and trips the frequency
converter to protect the motor.
30-23 Locked Rotor Detection Time [s]
Range:
Function:
Size related
*
[0.05 - 1 s] Time period for detecting the locked
rotor condition. A low parameter
value leads to faster detection.
30-24 Locked Rotor Detection Speed Error [%]
Range:
Function:
25 %
*
[0 - 100 %]
NOTICE
This parameter is available for FC 302
only.
30-25 Light Load Delay [s]
Range:
Function:
0.000 s
*
[0.000 -
10.000 s]
Use this parameter when the light load
detection is active. Enter the delay before
the frequency converter activates the light
load detection when the motor speed
reaches the reference in
parameter 30-27 Light Load Speed [%]
30-26 Light Load Current [%]
Range:
Function:
0 %
*
[0 -
100 %]
Use this parameter when the light load detection
is active. Enter the reference current, which is
used to determine if the motion of the lift is
obstructed and if the direction is to be changed.
The value is a percentage of nominal motor
current in
.
30-27 Light Load Speed [%]
Range:
Function:
0 %
*
[0 -
100 %]
Use this parameter when the light load detection
is active. Enter the reference speed during the
light load detection. The value is a percentage of
nominal motor speed in
. For standard asynchronous
motors, the synchronous speed is used instead of
parameter 1-25 Motor Nominal Speed
due to slip.
3.22.4 30-5* Unit Configuration
Parameters in this group allow to configure the operation
of internal units that communicate with the frequency
converter. The settings affect the behavior of hardware
components inside the frequency converter.
30-50 Heat Sink Fan Mode
Option:
Function:
[0] Simple Profile
NOTICE
This parameter is available in FC 302
only.
Select how the heat sink fan responds to
operating conditions. Use
to control the
minimum fan speed.
The simple profile is a passive fan control
based on the current temperature state of
