2. Wiring and Connection
2 - 8
2-3 NC and drive unit connection
The NC bus cables are connected from the NC to each drive unit so that they run in a straight line from
the NC to the terminal connector (battery unit). And up to 7 axes can be connected per system.
Note that the number of connected axes is limited by the NC.
CAUTION
Wire the SH21 cable between the NC and drive unit so that the distance
between the NC and terminal connector (battery unit) is within 30m.
POINT
Axis Nos. are determined by the rotary switch for setting the axis No. (Refer to
section "3-1-1 Setting the rotary switch".) The axis No. has no relation to the
order for connecting to the NC.
(1) When using one power supply unit
Connect the largest-capacity spindle drive unit to the final axis of the NC communication bus in
order to control the power supply unit. The spindle drive unit must be installed adjacent to the power
supply unit. In the system with servo only, a servo drive unit for controlling unbalance axis must be
installed in the same manner in the same way.
< Connection >
CN1A : CN1B connector on NC or previous stage's drive unit
CN1B : CN1A connector on next stage's drive unit or terminal connector (battery unit)
CN4 : Connector for communication between power supply unit (master side) and drive unit
Connect to the battery unit with a
terminal connector or SH21 cable.
Refer to the
instruction manual
of each NC for
details.
