CN2-42 Phase-Z (OC): Z (output)
Function
The port outputs phase-Z pulse signal of the encoder. The signal is outputted one pulse per every one
motor rotation. The signal may be used with the mechanical origin signal as a precise origin of the driven
mechanism.
Connection
(1) An example of [CN2-42 phase-Z: Z]
connection is shown in the figure to the
right.
(2) The port is opto-isolated.
(3) Plan the output circuit for the ports as
follows:
Supply voltage: DC24V or less
Signal current: 40mA or less
CN2-43 Output common: OUT-COM (output)
Function
This is the common port for the [CN2-33, 34, 38, 39, 40, 41, 42] ports.
