Omron CS1W-MCH71 MOTION CONTROL UNIT - 09-2004 Manual page 38

Performance Specifications
• 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.)
(2) The user must prepare the required power supply.
(3) The service life for the flash memory is 100,000 writing operations.
(4) The model CS1@-CPU@@H is the CPU Unit in which the IOWR/IORD in-
structions can be used. However, the version of the Unit decides whether
the Unit has the function or not. See below:
(a) CPU Units before Jan. 7, 2002 (Lot. 020107)
They do not have the function.
(b) CPU Units after April 18, 2003 (Lot. 030418)
They have the function.
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.

The actual ranges that can be set may be smaller than those shown above
depending on the pulse rate. The setting values must satisfy the following
conditions:
With INC Specification:
Minimum value: − 2147483648
Maximum value: 2147483647
With Limited Length Axis ABS Specification:
Minimum value: − (P5AA04 × P5AA06 × 2147483647)/(Encoder resolution ×
P5AA05)
Maximum value: (P5AA04 × P5AA06 × 2147483647)/(Encoder resolution ×
P5AA05)
With Unlimited Length Axis ABS Specification:
Minimum value: − (P5AA04 − 1)
Maximum value: P5AA04 − 1
P5AA04: Command unit/1 machine rotation
P5AA05: Gear ratio 1 (Motor rotation speed)
P5AA06: Gear ratio 2 (Machine rotation speed)
Example: With Limited length axis ABS specification, 1mm/rev, 16384 pulses/
rev with multiplication factor, and Minimum setting unit: 0.0001mm;
The value will be from − 131072000 to 131071999.
Additionally, the present positions that can be displayed on support
tools are to be within the range described in the above table.
