TM 5-3895-374-24-1ConnectionsAnalogue outputsThe variable speed controller has two 0-20 mA analogue outputs A01 and A02.The current supplied by these two outputs is proportional to:- A01 motor frequency,- A02 motor current.Maximum output voltage +10 V for a maximum Impedance of 500 WScale factor:- A01:20 mA corresponds to high speed (see settings p 48),A02:20 mA corresponds to 1,82 times the rated current of the speed controller(see characteristics) p. 10 and 11)NOTEThe two analogue outputs can be modified to 4-20 mA and assigned to other variables.Refer to the 21d part of this document "Special applications’ (p 81)Wiring precautions PowerThe frequency Inverter emits high frequency electromagnetic waves of low Intensity These cause interference signals, which may affect the operation of audio-frequency equipmentThis Interface can be reduced by screening the motor cables, ensuring a good earth and by fitting suppressors on the Incoming side of the controller (p 77)ControlAlthough the control inputs are protected and filtered, It Is recommended to reduce interferenceto a minimum by separating control circuits from power circuitsSpeed referenceThese circuits must be protected against interference signalsThe use of twisted cable is recommended, with a pitch of 25 to 50mm.(page 3-180)
