194Output CircuitWiring to the Connector, CN X5• The output circuit is composed of open collector transistoroutputs in the Darlington connection, and connect to relays orphoto-couplers.• There exists collector to emitter voltage, V CE (SAT) of approx.1V at transistor-ON, due to the Darlington connection of theoutput or. Note that normal TTL IC cannot be directly connec-ted since it does not meet VIL.• There are two types of output, one which emitter side of theoutput transistor is independent and is connectable individual-ly, and the one which is common to – side of the control pow-er supply (COM–).• If a recommended primary current value of the photo-coupleris 10mA, decide the resistor value using the formula of theright Fig.Sequence output circuitSO1 SO2• Feeds out the divided encoder outputs (A, B and Z-phase) indifferential through each line driver.• At the host side, receive these in line receiver. Install a termi-nal resistor (approx. 330Ω) between line receiver inputs with-out fail. • These outputs are not insulated.Line driver (Differential output) outputPO1• Feeds out the Z-phase signal among the encoder signals inopen collector. This output is not insulated.• Receive this output with high-speed photo couplers at thehost side, since the pulse width of the Z-phase signal is nar-row.Open collector outputPO2• There are two outputs, the speed monitor signal output (SP)and the torque monitor signal output (IM)• Output signal width is ±10V.• The output impedance is 1kΩ. Pay an attention to the inputimpedance of the measuring instrument or the external circuitto be connected.(1) Speed monitor output (SP)With a setup of 6V/3000r/min (Pr07=3), the resolution converted to speed is 8r/min/16mV.(2) Torque monitor output (IM) With a relation of 3V/rated torque (100%), the resolution converted to torque is 0.4%/12mV.Analog monitor outputAOFor the recommended primary current value, refer to the data sheet of apparatus or photo-coupler to be used.R [kΩ] =Install toward the direction as the fig. shows without fail.VDC [V] – 2.5[V] 10V DC12 – 24VSO1ALM+ etc.ALM– etc.COM–41ZSP, TLCSO2Max. rating 30V,50mAAM26LS32 or equivalent AM26LS31 or equivalentABZ2221OA+OA–OZ+OZ–OB+OB– 482325GND2449Connect signal ground of the host and the driver without fail.1925CZMax. rating 30V,50mAMeasuringinstrumentorexternalcircuitGNDHigh speed photo-coupler (TLP554 by Toshiba or equivalent)43 1kΩ1kΩSPIM42GND17represents twisted pair.represents twisted pair.
