1-2 System Configuration
The PCU receives control signals (CW limit, CCW limit, origin, origin proxim-
ity, emergency stop, and external interrupt input signals) from devices and a
control panel, and outputs pulse trains to stepping motor drivers and Servo
Drives.
1-2-1 CJ1W-NC413 System Configuration Example
Note (1) A dedicated cable is available for connecting the PCU to the dedicated
terminal block.
(2) Origin input signals cannot be used as external connection terminals with
dedicated terminal blocks. Connect the Z-phase signal to the Servo Drive
using the dedicated cable. The connecting cable required between the
PCU or dedicated terminal block and stepping motor driver is not provid-
ed.
