8.4 Option Card InstallationYASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical Manual 421Peripheral Devices &Options8Take the following steps to prevent erroneous operation caused by noise interference:• Use shielded wire for the PG encoder signal lines.• Limit the length of all motor output power cables to less than 100 m. Limit the length of open-collector output lines toless than 50 m.• Use separate conduit or cable tray dividers to separate option control wiring, main circuit input power wiring, andmotor output power cables.Interface Circuit• Complementary OutputFigure 8.8Figure 8.9 Complementary Outputs for the Interface Circuit• Open-Collector OutputsFigure 8.9Figure 8.10 Open-Collector Outputs for the Interface CircuitTerminal FunctionsTable 8.3 Option Terminal FunctionsTerminal Block Terminal Function DescriptionTB1<1> A separate UL Listed class 2 power supply is necessary when the PG requires more than 200 mA to operate.A+ A+ pulse signal input• Pulse signal inputs from the PG.• Signal inputs from complementary and open-collector outputs• Signal levelH level: 8 to 12 VL level: 2.0 V or lessA– A– pulse signal inputB+ B+ pulse signal inputB– B– pulse signal inputZ+ Z+ pulse signal inputZ– Z– pulse signal inputSD NC pin (open) For use when cables shields should not be groundedFE Ground Used for grounding shielded linesTB2IP PG power supply • Output voltage: 12.0 V ± 5%• Max output current: 200 mA <1>IG PG power supply commonAO A pulse monitor signal • Outputs the monitor signal for the A, B, and Z pulses from the PG speedcontrol card• For open collector outputs from the option• Max voltage: 24 V• Max current: 30 mABO B pulse monitor signalZO Z pulse monitor signalIG Monitor signal commonPG-B3 PG Encoder470 Ω330 Ω330 ΩA-,B-,Z-A+,B+,Z+IGAO,BO,ZO0VA,B,ZVccIPIG 0V12 VMonitor SignalsPGB3470 Ω330 Ω330 ΩA+,B+,Z+IGAO,BO,ZOIPIG12 V PG EncoderA,B,ZVcc0VA,B,ZMonitor SignalsAOIG IGZOIGBOIGIPA-A+ FESDZ-Z+B-B+TB1TB2
