hp]
Enter the nominal motor power in hp
according to the motor nameplate data.
The default value corresponds to the
nominal rated output of the unit.
Depending on the selections made in
parameter 0-03 Regional Settings, either
parameter 1-20 Motor Power [kW] or
parameter 1-21 Motor Power [HP] is made
invisible.
1-22 Motor Voltage
Range: Function:
Size
related*
[ 10 -
1000 V]
Enter the nominal motor voltage
according to the motor nameplate
data. The default value corresponds to
the nominal rated output of the
frequency converter.
1-23 Motor Frequency
Range: Function:
Size
related*
[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
parameter 4-13 Motor Speed High Limit [RPM]
and 3-03 Maximum Reference to the 87 Hz
application.
1-24 Motor Current
Range: Function:
Size
related*
[ 0.10 -
10000.00 A]
Enter the nominal motor current
value from the motor nameplate
data. The data are used for
calculating motor torque, thermal
motor protection and so on.
1-25 Motor Nominal Speed
Range: Function:
Size related* [100 - 60000
RPM]
Enter the nominal motor speed
value from the motor nameplate
data. The data are used for
calculating automatic motor
compensations.

Range: Function:
Size
related*
[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 parameter 1-10 Motor
Construction is set to [1] PM, non-salient
SPM, that is the parameter is valid for PM
and non-salient SPM motors only.
1-28 Motor Rotation Check
Option: Function:
WARNING
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 displays 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
[O] to stop the motor. Pressing [O] stops
the motor and resets parameter 1-28 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 veried. Enabling this
function overrides any bus commands or digital
inputs, except external interlock and Safe Torque
O (STO) (if included).
