Sigma II User’s Manual Appendix A: Host Controller Connection ExamplesA - 6A.5 Connecting OMRON's C500-NC112 Position Control UnitThe following diagram shows an example of connecting to the OMRON C500-NC112Position Con trol Unit. In this example, the servo amplifier is used in the position controlmode.*1. The ALM signal is output for approximately two seconds when the power is turnedON. Take this into consideration when designing the power ON sequence. The ALMsignal actuates the alarm detection relay 1Ry to stop main circuit power supply to theservopack.*2. Set the user parameter Pn200.0 to 1.*3. Manufactured by Yaskawa Controls Co.Note Only signals applicable to OMRON’s C500NC112 Position Control Unit andYaskawa’s SGDM servo amplifier are shown here.CN1CN2+-+12VI/O Power SupplyC500NC112(Made by OMRON)+12VCW LIMITCCW LIMITEMERGENCY STOPORIGINORIGIN PROXIMITYLOCALREADY+5VPULSE OUTPUT1A4A3B3A2B2A1B10B10A9B9A8B8A5B5A4B4Ry3Ry1Ry+5 V+24V8 712V *16 LRX01/A2*3012 V+24VINPOTNOTSON109313220191512118714474342403Ry +24 V4Ry1RyCN10VEXTERNALINTERRUPTServopackSGDML1CL3L2L1L2CPCO*PCOALM+ALM-PULSECLRSIGN*PULSE*CLR*SIGN012 VMPGWVU A (1)B (2)C (3)D (4)Servomotor*2Externalpowersupply+24 V*4(Made by OMRON) +24V+-+12VCW LIMITCCW LIMITEMERGENCY STOPEXTERNALINTERRUPTORIGINORIGIN PROXIMITYLOCALREADY+5VPULSE OUTPUT10A10B
