Specifications Section 1-5
Note 1. The MC Unit must be mounted to the CPU Rack to use D codes. D codes
will not be sent to the CPU Unit if the MC Unit is mounted to a CS Expan-
sion Rack.
2. The number of MC Units that can be mounted under one CPU Unit must
be determined based on the maximum number of Special I/O Units that
can be allocated words in the CPU Unit, the power supply capacity on the
CPU or Expansion Rack, and the current consumption of the Units mount-
ed to the Rack. Refer to the CPU Unit’s operation manual for details on cal-
culation methods.
3. To display units other than pulses in the CX-Motion, change the display unit
and then set the Pulse Rate to the amount of workpiece movement per
pulse.
4. The required power supply must be provided by the user.
5. The service life for the flash memory is 100,000 writing operations.
Task program
management Number of tasks 2 max. (program execution
units) 4 max. (program execution

Number of
programs The maximum number of
programs differs according to
the number of tasks.

Position data
capacity 2,000 positions max. (total for all axes)
Number of
registers 32 (Mainly used for specifying position data numbers.)
Subroutine
nesting 5 levels max.
Saving program
data MC Unit Backed up by flash memory. (See note 5.)
External
peripheral devices CX-Motion can be used to save data to a floppy disk or the hard
disk at the personal computer.
Program and position data
automatic download function When the operation number (program or position data) is
specified by an IOWR instruction from the CPU Unit, CX-Motion
recognizes it and downloads the program or position data to the
MC Unit.
Self-diagnostic function Memory corruption is detected.
Error detection functions Error counter warning, error counter over, absolute encoder error
detection, CPU errors, communications errors (Teaching Box),
flash memory error, EEPROM error, software limit over error,
phase-Z error, overtravel, emergency stop, unit number error,
driver alarm detection, driver reverse wiring detection, CPU Unit
error detection
Error log function Stores up to 20 error log records.
