Compax3 device description24 192-120102 N7 - February 20043.2.7. Control voltage 24VDC / enable (plug X4)PIN Description1 +24 V2 Gnd24 V3 Enable_in4 Enable_out_a5 Enable_out_bControl voltage 24 VDCController type Compax3Voltage range 21 - 27VDCCurrent drain of the device 0.8 ATotal current drain 0.8 A + Total load of the digital outputs +current for the motor holding brakeRipple 0.5VppRequirement according to safe extralow voltage (SELV) yesPower stage enable: X4/3=24 VDCTolerance range: 18.0 V ñ 33.6 V / 720 ΩThe +24V supply can be taken, for example, from Pin 1.Safe standstill (X4/3=0V)For implementation of the "Safe standstill" safety feature in accordance with theìprotection against unexpected start-upì described in EN1037. Please refer to therespective chapter (see on page 34) (can be found in the paper version"installation manual Compax3) with the circuitry examples!The energy supply to the drive is reliably shut off, the motor has no torque.A relay contact is located between X4/4 and X4/5 (normally closed contact)Enable_out_a - Enable_out_b Power outputstage isContact opened activatedContact closed deactivatedSeries connection of these contacts permits certain determination of whether alldrives are de-energized.Relay contact data:Switching voltage (AC/DC): 100 mV ñ 60 VSwitching current: 10 mA ñ 0.3 A
