3) 0 = Acceleration/deceleration ramps defined by parameters 23.12/23.13 in use. 1 =Acceleration/deceleration ramps defined by parameters 23.14/23.15 in use.4) Constant speed 1 is defined by parameter 22.26.5) See section DIIL input (page 135).6) Total load capacity of these outputs is 4.8 W (200 mA at 24 V) minus the power taken byDIO1 and DIO2.7) Determines whether DICOM is separated from DIOGND (ie. common reference for digitalinputs floats; in practice, selects whether the digital inputs are used in current sinking orsourcing mode). See also Ground isolation diagram (page 139). DICOM=DIOGND ON:DICOM connected to DIOGND. OFF: DICOM and DIOGND separate.8) Current [0(4)…20 mA, Rin = 100 ohm] or voltage [0(2)…10 V, Rin > 200 kohm] inputselected by switch AI1. Change of setting requires reboot of control unit.9) Current [0(4)…20 mA, Rin = 100 ohm] or voltage [0(2)…10 V, Rin > 200 kohm] inputselected by switch AI2. Change of setting requires reboot of control unit.￭ External power supply for the control unit (XPOW)The BCU-x2 is powered from a 24 V DC, 2 A supply through terminal block XPOW. A secondsupply can be connected to the same terminal block for redundancy.￭ DI6 as a PTC sensor inputA PTC sensor can be connected to this input for motor temperature measurement as follows.The sensor can alternatively be connected to FEN-xx encoder interface module. At thesensor end of the cable, leave the shields unconnected or ground them indirectly via ahigh-frequency capacitor with a few nanofarads, eg. 3.3 nF / 630 V. The shield can also begrounded directly at both ends if they are in the same ground line with no significant voltagedrop between the end points. See the firmware manual for parameter settings.T 3.3 nF> 630 V ACPTC DI6+24VDWARNING!As the inputs pictured above are not insulated according to IEC 60664, theconnection of the motor temperature sensor requires double or reinforced insulationbetween motor live parts and the sensor. If the assembly does not fulfill therequirement, the I/O board terminals must be protected against contact and mustnot be connected to other equipment or the temperature sensor must be isolatedfrom the I/O terminals.￭ AI1 or AI2 as a Pt100, Pt1000, PTC or KTY84 sensor inputThree Pt100/Pt1000 sensors or one KTY84 sensor for motor temperature measurementcan be connected between an analog input and output as shown below. (Alternatively, youcan connect the KTY to an FIO-11 or FAIO-01 analog I/O extension module or FEN-xxencoder interface module.) At the sensor end of the cable, leave the shields unconnectedor ground them indirectly via a high-frequency capacitor with a few nanofarads, eg. 3.3 nF134 Control units of the drive
