2-3 Drive unit connection
In this section, the connection between the spindle drive unit and power supply unit is shown. There is
space between units in the following diagram to make clearly understandable. However, actually, install
the drive units so that the space between the drive units is within 3cm.
POINT
Even if two or more spindle drive units are used, keep the setting of the spindle
drive unit’s rotary switch to “0”. This switch has no relation to the axis No.

(2) When using two power supply units and connecting one spindle drive unit with each power
supply unit
Two or more power supply units may be required if the spindle drive unit capacity is large in a
machine applying two spindles specification. Make sure that the powers (L+, L-) of both power
supply units are supplied to only one spindle drive unit connected with each power supply, and do
not connect each other's powers.

Connections when sharing one power supply
(Note 1) Connecting power supply unit and spindle drive unit.
Connect C1-CV CN4 and C1-SPA (No. 1) CN4 to C1-CV CN9 and C1-SPA (No.2) CN4. If
C1-SPA is connected with three or more axes, leave CN4 for C1-SPA (No. 3) and
following open.
Note that the C1-CV can be controlled (READY ON/OFF, alarm display, etc.) only by the
spindle drive unit connected to C1-CV CN4.
(Note 2) Make sure that the machine ready complete input turns ON and OFF simultaneously for all
the spindle drive units. Do not allow the signal to turn ON and OFF for only one spindle
drive unit.
(Note 3) When turning the machine ready complete input OFF during an emergency stop, always
have all the spindle drive units output the zero speed signal before turning the signal OFF.
(Note 4) If an alarm occurs in one of the spindle drive units, turn OFF the machine ready complete
input OFF for all the spindle drive units.
(Note 5) When connecting three or more spindle drive units, install the large-capacity spindle drive
units on both sides of the power supply unit.
