1-23 Motor FrequencyRange: Function:Applicationdependent*[20 - 1000 Hz] Select the motor frequency value from the motor nameplate data.For 87 Hz operation with 230/400V motors, set the nameplate data for 230 V/50 Hz. Adapt par. 4-13Motor Speed High Limit[RPM] and par. 3-03Maximum Reference to the 87 Hz application.NB!This parameter cannot be adjusted while the motor is running.1-24 Motor CurrentRange: Function:Applicationdependent*[Application dependant] Enter the nominal motor current value from the motor nameplate data. This data is used for cal-culating motor torque, motor thermal protection etc.NB!This parameter cannot be adjusted while the motor is running.1-25 Motor Nominal SpeedRange: Function:Applicationdependent*[100 - 60000 RPM] Enter the nominal motor speed value from the motor nameplate data. This data is used for calcu-lating automatic motor compensations.NB!This parameter cannot be adjusted while the motor is running.1-28 Motor Rotation CheckOption: Function:Following installation and connection of the motor, this function allows the correct motor rotationdirection to be verified. Enabling this function overrides any bus commands or digital inputs, exceptExternal Interlock and Safe Stop (if included).[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. 1-28Motor Rotation Check. If motor rotation direction is incorrect, twomotor phase cables should be interchanged. IMPORTANT:Mains power must be removed before disconnecting motor phase cables.6 How to Programme the Low Harmonic DriveVLT HVAC Low Harmonic Drive Operating In-structions88 MG.16.A1.02 - VLT® is a registered Danfoss trademark6
