Encoder wiring 4)
Following items should be noticed in encoder wiring: a)
PG wire should be laid separately and keep distance from control circuit and driver circuit

and forbidden to parallel with them.
PG wire should be shield wire, and shield layer should connect to PE near controller. (In

order to avoid being disturbed, only one terminal connects to ground.)
PG wire should be pulled on pipe separately, and metal crust should be connected to

ground credibility.
Encoder connection as follows: b)
Encoder connection of increment push-pull output and open collector output.
MCTC-MCB-A/B self-equipped with push-pull encoder trans-connection circuit. Its connection
is as follows:
Chart 4-7 connection of increment push-pull output and plough collector output encoder
Type U, V, W encoder wiring c)
For type UVW encoder, the controller of the main control board with the type MCTC-MCB-A
needs to equip with PG connection card MCTC-PG-B; the controller of the main control board
with the type MCTC-MCB-B needs to equip with PG connection card MCTC-PG-B and needs
to equip with MCTC-PG-D through the slot J12 on the main control board.

There are 15 user connection terminals and 16 pin interfaces with two lines, referring to
chart3-8. VCC and GND supply the encoder with work power; A+
