Wiring to the Connector, CN X7
Connector, CN X7
Power supply for the external scale shall be prepared by customer, or use the following power supply output
for the external scale (250mA or less).
Application
Power supply output
for external scale
I/F of external scale signals
(serial signal)
Frame ground
<Note>
EXOV of the external scale power supply output is connected to the control circuit ground which is
connected to the Connecter, CN X5.
<Remark>
Do not connect anything to other Pin numbers descried in the above table (Pin-3 and 4).
Cautions
(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 1/20<External scale ratio<20
If you set up the external scale ratio to smaller value than 50/position loop gain (Pr10 and 18), you may
not be able to control per 1 pulse unit. Setup of larger scale ratio may result in larger noise.
