Attach the connector as follows:
• Use the connector (snap-on type) provided with the Unit.
• Use the anti-electrostatic screws provided with the Unit. There are eight
screws for the CS1W-MC421 and four for the CS1W-MC221.

The following table gives the names of the CS1W-MC221 I/O connector pins,
and explains their functions.

X-axis CW limit input
Y-axis CW limit input
X-axis CCW limit input
Y-axis CCW limit input
X-axis emergency stop input Disables the X-axis run output and stops it.

1. "NC" stands for normally closed and "NO" stands for normally open.
2. Either NC or NO logic can be used for the origin proximity inputs. This set-
ting is a machine parameter.
3. Pin numbers 15, 20, 23, and 24 are not used.
4. General outputs cannot directly drive the motor brake. They must be uti-
lized through bit control.
5. Always short unused NO input terminals to the DC ground on the connec-
tor.
Function
Connects to the + terminal of the 24-VDC external
power supply.
Limits movement of the X axis in the CW direction.
Limits movement of the Y axis in the CW direction.
Limits movement of the X axis in the CCW direction.
Limits movement of the Y axis in the CCW direction.
Disables the Y-axis run output and stops it.
General input 1

Used for the X-axis origin search.
Used for the Y-axis origin search.
General output 1 or X-axis brake signal output
General output 2 or Y-axis brake signal output
Connects to the – terminal (0 V) of the 24-VDC
external power supply.
