The zone bit turns ON when any variable (including feedback present position, feed-
back speed, etc.) is within the set range, and OFF when outside of the set range.
A maximum of 32 zones can be set.
A maximum of two groups can be simultaneously traced, with 1 to 16 data items in
each group.
Note The items that can be traced are bits and data. These are each handled as a
single item.
The number of data samples that can be collected is 2,048 samples when 16 items
are set for tracing to 32,768 when only 1 item is set for tracing.
Watchdog, FLASH-ROM check, RAM check, etc.
Deceleration stop input, unit number error, CPU Unit error, software limit over errors,
etc.
The error log is to be read from the CPU Unit by means of the IORD instructions as
needed.
Alarm reset
Third party access to program and CAM data can be restricted using the CX-Motion-
MCH version 2.1 read protection function (password setting).
(1) To determine the number of MC Units that can be mounted under one
CPU Unit, examine the followings:
• Maximum number of CPU Bus Units that can be allocated words in the
CPU Unit being used
• The capacity of the power supply unit used for each rack (CPU Unit
and Expansion Rack) and the current consumption of the units mount-
ed on the racks. (Refer to the CPU Unit's operation manual for details
on calculation methods.)
• Number of Units (CJ1W-MCH71 only)
Each MC Unit requires the space of three standard Units. Although
normally up to 10 CPU Bus Units can be connected in the CPU Rack
or in each Expansion Rack, a maximum of only 3 MC Units can be
mounted per Rack.
(2) The user must prepare the required power supply.
(3) The service life for the flash memory is 100,000 writing operations.
(4) The IOWR/IORD instructions can be used with CJ-series CPU Units with
unit version 2.0 or later.
CS-series CPU Unit models are in the format CS1@-CPU@@H. The following
conditions apply to certain CPU Units.
(1) CPU Units manufactured prior to January 7, 2002 (Lot No. 020107) do not
support the IOWR/IORD instruction.
(2) Standard CPU Units manufactured after April 18, 2003 (Lot No. 030418)
support the IOWR/IORD instruction.
The maximum command values and software limit values will be as shown in
the following table corresponding to the position command decimal point posi-
tion.
