*
[20 -
1000 Hz]
Select the motor frequency value from
the motor nameplate data. For 87 Hz
operation with 230/400 V motors, set the
nameplate data for 230 V/50 Hz. Adapt
4-13 Motor Speed High Limit [RPM]
and
3-03 Maximum Reference
to the 87 Hz
application.
NOTE
This meter cannot be changed while the motor is running.

[ 0.10 -
10000.00 A]
Enter the nominal motor current
value from the motor nameplate
data. This data is used for
calculating motor torque, motor
thermal protection etc.
NOTE
This parameter cannot be changed while the motor is
running.
1-25 Motor Nominal Speed
Range:
Function:

*
[100 - 60000
RPM]
Enter the nominal motor speed
value from the motor nameplate
data. This data is used for
calculating automatic motor
compensations.
NOTE
This parameter cannot be changed while the motor is
running.
1-26 Motor Cont. Rated Torque
Range:
Function:

*
[0.1 -
10000 Nm]
Enter the value from the motor
nameplate data. The default value
corresponds to the nominal rated
output. This parameter is available
when
is set to
[1] PM, non salient SPM
, i.e. the
parameter is valid for PM and
nonsalient SPM motors only.
1-28 Motor Rotation Check
Option:
Function:
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

Enabled Motor Rotation Check is enabled.
NOTE
Once the motor rotation check is enabled the display
shows: “Note! Motor may run in wrong direction”.
Pressing [OK], [Back] or [Cancel] will dismiss the message
and display a new message: “Press [Hand On] to start the
motor. Press [Cancel] to abort”. Pressing [Hand On] 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
. If
motor rotation direction is incorrect, two motor phase
cables should be interchanged.
WARNING
Mains power must be removed before disconnecting
motor phase cables.

NOTE
1-29 Automatic Motor Adaptation (AMA)

Activate the AMA function by pressing [Hand on] after
selecting [1] or [2]. See also the item

the display will read: “Press [OK] to finish AMA”. After
pressing the [OK] key the frequency converter is ready for
operation.
