When driving a reactive load, such as a relay coil, always insert a flywheel diode as shown in Fig 2.20.* 3. Pulse input specifications are given in the following table.* 4. Use the photocoupler outputs when the minimum permissible load is 5 VDC or less and 10 mA or less.Fig 2.20 Flywheel Diode ConnectionRelayoutputsMA Fault output signal (NO con-tact) Fault when CLOSED across MA and MCFault when OPEN across MB and MCDry contactsContact capacity:10 mA min., 1 A max. at250 VAC10 mA min., 1 A max. at30 VDCMinimum permissibleload: 5 VDC, 10 mA *4MB Fault output signal (NC con-tact)MC Relay contact output com-mon -M1 Multi-function contact output(NO contact)Factory setting: OperatingOperating when CLOSED across M1 andM2.M2Analogmoni-tor out-putsFM Multi-function analog moni-tor 1Factory setting: Output frequency0 to 10 V/100% frequency-10 to +10 VDC ±5%2 mA max.AM Multi-function analog moni-tor 2Factory setting: Current monitor5 V/Inverter's rated currentAC Analog common -PulseI/ORP Multi-function pulse input *3 Factory setting: Frequency reference input(H6-01 = 0) 0 to 32 kHz (3 kΩ)MP Multi-function pulse monitor Factory setting: Output frequency(H6-06 = 2) 0 to 32 kHz (2.2 kΩ)RS-485/422R+ MEMOBUS communica-tions input For 2-wire RS-485, short R+ and S+ as wellas R- and S-.Differential input, photo-coupler isolationR-S+ MEMOBUS communica-tions outputDifferential output, pho-tocoupler isolationS-IG Communications shield wire - -Low level voltage 0.0 to 0.8 VHigh level voltage 3.5 to 13.2 VH duty 30% to 70%Pulse frequency 0 to 32 kHzTable 2.11 Control Circuit Terminals (Continued)Type No. Signal Name Function Signal LevelExternal power:48 V max.CoilFlywheel diode50 mA max.The rating of the flywheel diodemust be at least as high as thecircuit voltage.
