Parker EME Compax3 device description192-120102 N15 June 2008 253.3.4. Motor / Motor brake (C3S connector X3)PIN Designation1 U (motor)2 V (motor)3 W (motor)4 PE (motor)5 BR+ Motor holding brake *6 BR- Motor holding brake ** Please note that Compax3 will report error "open circuit at holding brake"(5481h / 2163d) if the current is < 150mA.If needs be, use a parallel resistor of 150Ohm for relay control!Requirements for motor cable<100 m (the cable must not be rolled up!)A motor output filter is required for motor cables >20m :Shielding connection of the motor cableThe cable should be fully screened and connected to the Compax3 housing. Weoffer a special Shield connecting terminal as accessory item (ZBH./...).The shield of the cable must also be connected with the motor housing. The fixing(via plug or screw in the terminal box) depends on the motor type.Motor holding brake!Connect the brake only on motors which have a holding brake! Otherwi-se make no brake connections at all.Requirements cables for motor holding brakeIf a motor holding brake is present, a cable of the motor holding brakemust be fed on the device side through the toroidal core ferrite providedas accessory ZBH0x/xx (63Ω @1MHz, di=5.1mm), in order to ensureerror-free switching on and off of the motor holding brake.Motor holding brake outputMotor holding brake output Compax3Voltage range 21 – 27VDCMaximum output current (short circuitproof)1.6AMinimum output current 150 mAMotor cable
