4 INSTALLATION AND WIRING
POINT
(1) Use a different 24VDC power supply for the Motion controller and for I/O
signals.
(2) Use a different 24VDC power supplies for the Motion controller and the
electromagnetic brake of the servo motor.
(3) Refer to Section 2.5.1(10) for the pin layout of 24VDC power supply connector,
and refer to APPENDIX 4.3 for the connection diagram of 24VDC power
supply cable.
(4) Motion controller and 24VDC power supply are an open type device and must
be installed in a control panel for use.
This not only ensures safety but also ensures effective shielding for Motion
controller and 24VDC power supply generated electromagnetic noise.
(5) Use the thickest possible (up to 2mm
2
) wires for the 100/200VAC and 24VDC
power cables. Be sure to twist these wires starting at the connection terminals.
For wiring a terminal block, be sure to use a solderless terminal. To prevent a
short circuit should any screws loosen, use solderless terminals with insulation
sleeves of 0.8mm (0.03inch) or less.
Also, only two solderless terminals can be connected per terminal block.

(6) Ensure that the earth terminals LG and FG are grounded.
(Ground resistance :
100
or less)
If not, the programmable controller may become susceptible to noise.
Since the LG terminal has a half of the input voltage, touching this terminal
may result in an electric shock.
(7) No system error can be detected by the
ERR
terminal of an extension base
unit. (The
ERR
terminal is always set off.)
