supply units are supplied to only one spindle drive unit connected with each power supply, and do
not connect each other's powers.

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
