Function Upgrades from
Unit Version 2.0 to 3.0
xx
Backup and Restore Functions
Previous versions
(Unit Ver. 3.0 and earlier)
The origin compensation value
when an absolute encoder is used
is backed up using the CPU Unit's
easy backup function.
Program and CAM Data Read Protection
Previous versions
(Unit Ver. 3.0 and earlier)
There is no program and CAM
data read protection.
Expanded Allocations in Custom I/O Area
Previous version (Unit Ver. 2.0)
Only the I/O variable area determined in
advance could be allocated to the Cus-
tom I/O Area.
Digital Input Values Changed to Improve Noise Resistance
Previous version
(Unit Ver. 2.0)
Rated input voltage: 24 VDC ±10%
Rated input current: 4.06 to 4.48 mA
ON voltage: 9.5 V min.
OFF voltage: 4.5 V max.
Parameter Added for Faster Unit Cycle and Communications Cycle Time
Previous version
(Unit Ver. 2.0)
Unit cycle [us] = (115.0 × Number of
axes) + (165 × Number of motion tasks ×
Number of parallel branches) + (0.3 ×
Number of general allocation words) +
350.0
Communications cycle [us] = ((Number of
allocated Units + Number of retries) ×
133.3+26.2) × 1.1
Current version
(Unit Ver. 3.1)
Origin compensation values can be backed up
even with CX-Motion-MCH version 2.1. For
details, refer to Section 11 Backup and Restore
in the CX-Motion-MCH Operation Manual (Cat.
No. W448).
Current version
(Unit Ver. 3.1)
The CX-Motion-MCH version 2.1 read protection
function (password setting), can be used to pre-
vent third-parties from reading program and
CAM data. For details, refer to Section 12 Read
Protection in the CX-Motion-MCH Operation
Manual (Cat. No. W448).
Present version (Unit Ver. 3.0)
In addition to the I/O variables, system
variables, global general variables, posi-
tion data, and task variables for user-
specified addresses can be allocated to
the Custom I/O Area.
Current version
(Unit Ver. 3.0)
Rated input voltage: 24 VDC ±10%
Rated input current: 4.02 to 4.52 mA
ON voltage: 14 V min.
OFF voltage: 6V max.
(Any sensors that were previous used can
still be used.)
Current version
(Unit Ver. 3.0)
Unit cycle [us] = (85 × Number of axes) +
(120 × Number of motion tasks × Number
of parallel branches) + (0.3 × number of
general allocation words) + 200
Communications cycle [us] = ((Number of
allocated Unit + Number of retries) ×
102.7 + 19.2) × 1.1
Use the following parameter to switch the
performance.
• Parameter number: P00004
• Bit: 09 (previously reserved)
0: Initial value. Performance is the
same as before.
1: Selects faster performance.
