Enter the nominal motor current
value from the motor nameplate
data. This data is used for
calculating motor torque, motor
thermal protection, etc.
NOTICE!
This parameter cannot be adjusted while the motor is
running.

Enter the nominal motor speed
value from the motor nameplate
data. This data is used for
calculating automatic motor
compensations.
NOTICE!
This parameter cannot be adjusted while the motor is
running.
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
inputs, except External Interlock and Safe Stop (if
included).

OFF
Motor Rotation Check is not active.
[1]
Enabled Motor Rotation Check is enabled.
NOTICE!
Once the motor rotation check is enabled, the display
shows: "Please 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 the forward direction; 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 1-28 Motor Rotation Check
. If motor rotation
direction is incorrect, two motor phase cables should be
interchanged.
WARNING
Line power must be removed before disconnecting
motor phase cables.

no overvoltage arises in the inverter due to
regenerative operation of the motor, and
