3.4 CN1 Wiring and Signal
CN1 is the connector located at the right
lower part of the front of drive system. This
connector is used to connect the drive
system with the upper control system which
commands the operation.
The figure on the right side shows the pin
array of the connector CN1 seen from the
user side connector.
(Note 1) CN1 connector is an option item.
∗ Maker: 3M
∗ Case name: 10350-52FO-008
∗Connector (For soldering): 10150-3000VE
3.4.1 Encoder output signal
The encoder signal is produced based on 0 [V] (GND) of control power supply. Connect 0 [V]
terminal of the circuit which receives this signal from the upper control system to the GND terminal
of CN1. Encoder signal is produced in line driver system after the AC servo motor encoder signal
received from CN2 is divided according to the frequency dividing ratio set by the sub-menu [Pulse
Out Rate (P2-07)] of the main menu [Control Mode (P2-)]. Functions of each signal is as follows.
Signal function A phase output B phase output Z phase output
