Program Example for Circular Mode
Section 7-7
Operation
The control timing of a device connected to the shaft drive of the motor is
detected by the incremental encoder, and outputs are controlled according to
the angle of rotation.
Offset phase inputs multiplied by 4 are input to the encoder.
BCD data is used in the system.
The counter is reset at the rising edge of external counter input Z and Internal
Reset Flag. (Mode 6)
Switch Settings
The unit number of the High-speed Counter Unit is set to 1 and the High-
speed Counter Unit will have NPN external outputs.
Wiring
Connect the A-, B-, and Z-phase outputs of the incremental encoder to
counter 1 inputs A, B, and Z.
Connect external outputs 1, 6, and 7 the control component of the system.

While the start switch is ON, external
outputs are enabled and the counter
continues counting.
Reset switch
Counter input Z
The counter is reset at the rising
edge of the first counter input Z after
the counter reset switch is pressed.
