Parameter Description
H-43 Torque Characteristics
Option: Function:
has a default value and is automatically
adjusted when the motor data is
programmed. These settings ensure optimum
motor voltage. If the motor power factor cos
phi requires tuning, an auto tune function
can be carried out using parameter P-04 Auto
Tune. It is rarely necessary to adjust the motor
power factor parameter manually.
H-48 Clockwise Direction
Option: Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
This parameter defines the term clockwise
corresponding to the keypad 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 counterclockwise direction
when the frequency converter is connected U⇒U,
V⇒V, and W⇒W to the motor.

H-50 Motor Magnetisation at Zero Speed
This parameter is not visible on the LCP.
Range: Function:
NOTICE
100 % [0 -
300 %]
*
Parameter H-50 Motor Magnetisation at
Zero Speed has no effect when
parameter P-20 Motor Construction = [1]
PM, non-salient SPM.
Use this parameter along with
parameter H-51 Min Speed Normal Magnetising
[RPM] to obtain a different thermal load on the
motor when running at low speed.
Enter a value which is a percentage of the rated
magnetizing current. If the setting is too low,
the torque on the motor shaft may be reduced.

NOTICE
[10 -
300 RPM]
Parameter H-51 Min Speed Normal
Magnetising [RPM] has no effect when
parameter P-20 Motor Construction=[1]
PM, non-salient SPM.
Set the required speed for normal
magnetizing current. If the speed is set
lower than the motor slip speed,
parameter H-50 Motor Magnetisation at Zero
Speed and parameter H-51 Min Speed
Normal Magnetising [RPM] are of no signif-
icance.
Use this parameter along with
parameter H-50 Motor Magnetisation at Zero
Speed. See Table 3.10.
Function:
NOTICE
[0.3 -
10.0 Hz]
Parameter H-52 Min Speed Normal
Magnetising [Hz] has no effect when
parameter P-20 Motor Construction = [1]
PM, non-salient SPM.
Set the required frequency for normal
magnetising current. If the frequency is set
lower than the motor slip frequency,
parameter H-50 Motor Magnetisation at Zero
Speed and parameter H-51 Min Speed Normal
Magnetising [RPM] are inactive.
Use this parameter along with
parameter H-50 Motor Magnetisation at Zero
Speed. See Table 3.10.
