Automatic
and Manual
Mode Backlash correction The amount of correction for backlash in the
mechanical system can be registered in advance.
Error counter reset Forcibly resets the error counter to 0, and stops
axis operation. (Enabled when no speed
reference is provided to the servo driver.)
Override Changes the operating speed by applying a
specified percentage to the speed specified in the
system parameters or G-language program.
Zones A zone flag turns ON when the present position
enters a preset range.
Unlimited Feed Mode, unlimited
present position display Moves the axis with no limit. In this mode, a range
for refreshing the present position can be speci-
fied.
Origin search function The search pattern can be selected to shorten
the origin search time. Either a deceleration stop
or accumulated pulse stop can be selected for
when a limit input is received during the origin
search.
Trapezoid/S-curve acceleration and
deceleration Either trapezoid or S-curve acceleration and
deceleration can be specified for starting and
stopping each axis.
Driver alarm reset Resets the servo driver alarm.
Data transfer Data is transferred between the CPU Unit and the
MC Unit by means of the CPU Unit’s IORD and
IOWR instructions. There are two modes for
transferring data: One for transferring large
amounts of data, and another for rapidly
transferring small amounts of data.
Servo data trace function Up to 500 data items, including speed reference
values, present speed, and error counter data,
can be traced for each axis. This data can be
referenced by CX-Motion.

Power ON startup time Average: 600 ms Time from turning ON the power until
manual operation commands are
accepted.
Cyclic service time MC221: 0.8 ms/Unit
MC421: 0.85 ms/Unit Time by which the CPU Unit cycle
time will be extended per MC Unit.

extended when IOWR is executed.
IORD execution time 0.8 ms/instruction Time by which the cycle time will be
extended when IORD is executed.
Data write time 475 ms/1,000 words Time from when IOWR is executed
until data transfer is completed.
Data read time 470 ms/1,000 words Time from when IORD is executed
until data transfer is completed.
