Model
CS1W-MC221 • 1 task and 2 axes are used.
• All axes are in servo-lock status (stopped).
• Zones are not being used.
CS1W-MC421 • 1 task and 4 axes are used.
• All axes are in servo-lock status (stopped).
• Zones are not being used.

The function of these bits depends on the settings for the output ports in the
unit parameters in the system parameters. They can be set for either general
outputs or brake outputs.
General Outputs
The bits can be turned ON or OFF to turn ON or OFF the corresponding out-
put ports. Bits 00 to 03 correspond to outputs 1 to 4.
Brake Outputs
The bits can be turned ON or OFF to turn ON (release) or OFF the corre-
sponding brake outputs on the output ports. The servo must be unlocked for
the corresponding axis for these bits to be effective. If the servo is locked,
changes in the bit status will be ignored. Also, if the servo is locked for an axis
when the brake output is ON, changes in the bit status will be ignored as long
as the servo remains locked.
The CS1W-MC221 does not have brake outputs X and U.
turned ON for that axis when the servo is unlocked, the axis will descend. You
must confirm safety before turning ON a Brake Output Bit.
Signal
1 Turns ON output port. (Turns ON brake output.)
0 Turns OFF output port. (Turns OFF brake output.)
