Function:
WARNING
HIGH VOLTAGE
Frequency converters contain high voltage
when connected to AC mains input, DC
supply, or load sharing.
•
Remove mains power before
disconnecting motor phase cables.
NOTICE
Once the motor rotation check is enabled,
the display shows: Note! Motor may run in
wrong direction.
Pressing [OK], [Back], or [Cancel] dismisses
the message and shows a new message:
Press [Hand] to start the motor. Press
[Cancel] to abort. Pressing [Hand] starts the
motor at 5 Hz in forward direction and the
display shows: Motor is running. Check if
motor rotation direction is correct. Press
[Off] to stop the motor. Pressing [Off] stops
the motor and resets parameter P-08 Motor
Rotation Check. If motor rotation direction
is incorrect, interchange 2 motor phase
cables.
Following installation and connection of the
motor, this function allows the correct motor
rotation direction to be verified. Enabling this
function overrides any bus commands or digital
inputs, except external interlock.
Motor rotation check is not active.

Parameter P-09 Slip Compensation has no
effect when parameter P-20 Motor
Construction = [1] PM, non-salient SPM.
Enter the % value for slip compensation to
compensate for tolerances in the value of n
Slip compensation is calculated automatically,
that is on the basis of the rated motor speed
n .

NOTICE
Parameter P-10 Slip Compensation Time
Constant has no effect when
parameter P-20 Motor Construction = [1]
PM, non-salient SPM.
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 arise, use a
longer time setting.
Function:
For asynchronous motors.
Use for non-salient PM motors.
Function:
The damping gain stabilizes the PM machine to
run the PM machine smooth and stable. The
value of damping gain controls the dynamic
performance of the PM machine. High damping
gain gives low dynamic performance, and low
damping gain gives high dynamic performance.
The dynamic performance is related to the
machine data and load type. If the damping gain
is too high or low, the control becomes unstable.
Function:
High-pass filter damping time constant
determines the response time to load steps.
Obtain quick control through a short
damping time constant. However, if this
value is too low, the control becomes
unstable. This time constant is used below
10% rated speed.
