40System Configuration and WiringCautions(1) Following external scale can be used for full-closed control.• AT500 series by Mitutoyo (Resolution 0.05[μm], max. speed 2[m/s])• ST771 by Mitutoyo (Resolution 0.5[μm], max. speed 2[m/s])(2) Recommended external scale ratio is 1/20If you set up the external scale ratio to smaller value than 50/position loop gain (SV.Pr10 and 18), youmay not be able to control per 1 pulse unit. Setup of larger scale ratio may result in larger noise.Wiring to the External Scale, Connector, CN X7Wire the signals from the external scale to the external scale connector, CN X7.1) Cable for the external scale to be the twisted pair with bundle shielding and to having the twisted corewire with diameter of 0.18mm 2 .2) Cable length to be max. 20m. Double wiring for 5V power supply is recommended when the wiringlength is long to reduce the voltage drop effect.3) Connect the outer film of the shield wire of the external scale to the shield of the junction cable. Alsoconnect the outer film of the shield wire to the shell (FG) of CN X7 of the driver without fail.4) Separate the wiring to CN X7 from thepower line (L1, L2, L3, L1C(r), L2C(t),U, V. W, ) as much as possible (30cmor more). Do not pass these wires inthe same duct, nor bundle together.5) Do not connect anything to the vacantpins of CN X7.6) Cut away the driver's CN X7 cover.ContentEX5VEX0VEXPSEXPSFGConnectorPinNo.1256CaseApplicationPower supply outputfor external scaleI/F of external scale signals(serial signal)Frame groundExternal scale sideExternal scale unitDetection headJunction cableServo driverEX5VEX0VEX5VEX0VEX5VEX0VEX5VCN X7EX0VEXPSEXPS3142111312+5V0V34567815RegulatorHDAB-15P(by Hirose Electric Co.)HDAB-15S(by Hirose Electric Co.)55100-0600(by Molex Inc.)Twisted pairEXPSFGEXPSX6X7Please cut it out with nippers etc.Wiring to the Connector, CN X7 (Connection to External Scale)Power supply for the external scale shall be prepared by customer, or use the following power supply outputfor the external scale (250mA or less).EXOV of the external scale power supply output is connected to the control circuit ground which isconnected to the Connecter, CN X5.Do not connect anything to other Pin numbers descried in the above table (Pin-3 and 4).
