ent*
[100 - 60000 RPM] Enter the nominal motor speed value from the motor nameplate data.
This data is used for calculating automatic motor compensations.
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.
[0] * Off Motor Rotation Check is not active.
[1] Enabled Motor Rotation Check is enabled. Once enabled, 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 par. 1-28
Motor Rotation Check. If motor rotation direction is incorrect,
two motor phase cables should be interchanged. IMPORTANT:
Hazardous Voltage!
Main power must be removed before disconnecting motor phase cables. Failure to follow recommendation could result
in death or serious injury.
