How to Connect the Counter Input Signal
You can connect to a rotary encoder or linear scale with a TTL level output circuit, or to
an open-collector output circuit. The signal must be an LVTTL level input and can be up to 10MHz.
As pull-up resistors are provided on the board, connect the pull-up voltage to the pull-up pins if
connecting to an open collector output circuit/TTL level output circuit. (Please match the pull-up
voltage to the driving voltage on output side IC. If using 3.3V, connect to the VCC pin on the board.)
Not connecting the pull-up voltage may affect the counter input channel left unconnected.
For a two-phase input, connect both phase A and phase B. For a single phase input, connect to either
phase A or phase B. If not using the Z phase, this does not need to be connected.
Remarks
The pull-up pins are PUP1 (pin 32 *1) for the counter input signal and PUP2 (pin 66 *1) for the
control input signal.
PUP1 (pin 32): Pull-up for A, B, and Z phase input signal
(A0, B0, Z0, A1, B1, Z1, A2, B2, Z2, A3, B3, Z3).
PUP2 (pin 66): Pull-up for the control input signals and for the sampling input signals
(DI0, DI1, DI2, DI3, CLKIN, STARTIN, STOPIN).
*1: Connector pin number on the board.
Example Connection for Counter Input Circuit
*1: The pull-up pins are PUP1 for the counter input signal and PUP2 for the control input signal.
