(2) Contactor shutoff sequence
During the emergency stop signal input (EMG), if the setting of SP193 is "0" or "1" after the spindle
motor decelerates to stop, the contactor is turned OFF after a certain amount of time. Even in the
emergency stop, the contactor is turned OFF immediately after the machine ready complete signal
(RDY) is turned OFF.

2-6-1 Input interface
(1) Digital input interface: CN10 to 12
(Special input: 3 points, general-purpose input: 12 points, multi-points orientation command: 12
points, digital speed command: 12 points)
Select from the following.
1) Connecting with contact 2) Connecting with photo coupler

(Note 1) A +24V(±10%) power supply is required for this unit. The required maximum power supply capacity is 26W. DC stabilized
power supply must be used here.
(Note 2) Common for dedicated/general-purpose input is CES1, common for digital speed command is CES2, and common for
multi-point orientation command is CES3. Each command is electrically separated one another.
Thus, when using CES1, 2 or 3, each of them has to be connected to one of the signals (power supply, etc.).
(Note 3) Filter time constant at the input section is 5 to 15ms.
(Note 4) When running the motor on a trial basis, (when only "machine ready complete", "forward run" and "reverse run" are input
and all the other 24V I/O are not used.), external +24V power supply is exceptionally not necessary; internal +24V power
supply will do. In this case, use CN10-7 pin for +24V, CN10-10 pin for RG (24G).
(Note 5) Power supply unit's CN23 is a similar circuit; however, the resistance is not 4.7kΩ but 2kΩ.
