6. Operation
- Do not change the controller's function switch settings during the
operation; otherwise, it will cause injury.
- Do not approach the machine after instantaneous power failure
has been recovered.
Doing so may result in injury if the machine starts abruptly, it will
cause injury.
- Be sure to check that the power supply specifications are correct;
otherwise, it may caused controller failure.
- Be sure to provide an external emergency stop circuit so that
operation can be stopped with power supply terminated immediately.
- Be sure to conduct independent trial runs for the controller before
mounting the controller to the machine;
otherwise, it may cause injury.
- When an error occur, be sure to eliminate the cause, ensure
safety, and reset the error before restarting operation;
otherwise, it may cause injury.
7. Maintenance And Inspection
- Do not disassemble, remodel, or repair the unit;
otherwise, it will cause electric shock, fire, and unit malfunction.
- The capacitor of the power line deteriorates through prolonged use.
We recommended that the capacitor be replaced every five years
to prevent secondary damage.
8. Disposal
- Be sure to handle the controller as industrial waste while
disposing of it.
1. Handling Precautions
- Do not touch components inside of the controller;
otherwise, it will cause electric shock.
- Do not damage the cable by applying excessive load, placing
heavy objects on it, or clamping;
otherwise, it will cause electric shock or fire.
DANGER
- Turn the power supply OFF before wiring, transporting, and inspecting
the controller; otherwise, it may cause electric shock.
- Provide an external safety circuit so that the entire system
functions safely even when the controller is faulty.
- Connect the grounding terminal of the controller;
otherwise, it may case electric shock or malfunction.
- Do not use the controller in the following places; water splashes,
the atmosphere of the corrosion, the atmosphere of the flammable
vapor, and the side of the combustibility.
Doing so may result in fire or the controller may become faulty.
- Be sure to use the controller and the ABSOCODER sensor in the
environment designated by the general specifications in the manual.
Failure to do so may result in electric shock, fire, malfunction or unit
failure.
- Be sure to use the specified combination of the ABSOCODER
sensor, controller and sensor cable; otherwise, it may cause fire or
controller malfunction.

4. Installation
- Do not step on the ABSOCODER sensor or place heavy objects on
the controller; otherwise, it will cause injury.
- Do not block the exhaust port or allow any foreign matter to enter
the controller; otherwise, it will cause fire or unit failure.
- Be sure to secure the controller and ABSOCODER sensor with the
provided brackets; otherwise, it may cause malfunction, injury, or
drop.
- Be sure to secure the specified distance between the main body
and the control panel or other equipments; otherwise, it may cause
malfunction.
5. Wiring
- Be sure to secure the terminal block firmly; otherwise, it may have
risk of fire.
- Be sure to mount the terminal cover provided with the controller,
before supplying the power, starting operation after the installation,
and wiring; otherwise, it may cause electric shock.
- Be sure to keep the sensor cable, control cable, and communication
cable at least 300 mm away from the main circuit and power line;
otherwise it may cause injury or malfunction.
- Be sure to connect all cables correctly; otherwise, it may cause injury
or controller malfunction.
- Be sure to firmly connect the external I/O connectors and sensor
connectors; otherwise, it may cause incorrect inputs and outputs or
injury.

1. SUMMARY
1-1. Summary
This manual describes the specifications and instruction procedures for the VE-2CC/VM-2CC which is able to
connect to the open-architecture network "CC-Link".
VE-2CC/VM-2CC is a converter which can detect the machine's current position value by ABSOCODER.
The ABSOCODER sensor uses a magnetic position detection format, thereby the incremental format encoder
which has been used can be replaced to VE-2CC/VM-2CC.
This converter can be used for the automatic controlling which needs position detections, such as the conveyor,
press machine, assembly machine, packing machine and etc.
The detected position data can be read by the host controller via CC-Link, so the system is able to reduce the
wiring.
1-2. Features
Features of VE-2CC/VM-2CC
(1) Absolute position detection
An absolute position detection format ensures accurate position detection even if a power interruption
condition occurs. An origin returning operation is not required.
(2) High-resolution position detection
[1] VE-2CC: 8192 divisions / turn x 1 turn
[2] VM-2CC: 4096 divisions / turn x 32 turns (In the case of using MRE-32SP062)
If ABSOCODER that "the total number of turn" is twice as much as "MRE-32SP062" is used, the
number of divisions is 1/2 per turn.
(3) Connects with CC-Link
The position data, current position value setting data, and error signal can be sent or received on CC-Link.
(4) Self-diagnosis function
The following self-diagnosis result can be checked by the remote input (RX).
- Internal CPU error (watchdog timer error)
- Memory error
- Sensor error (The sensor is disconnected or severed.)
- Low-voltage detection
(5) Current position setting function
The position data can be designated as desired value from the host controller.

5. INSTALLATION AND PRECAUTIONS
5-1. Converter Installation Conditions and Precautions
The installation conditions and precautions for each of the system components are described in this section.
- Installation Site
(1) Avoid sites where the unit is exposed to direct sunlight.
(2) The ambient temperature should never exceed a 0 to 55°C range.
(3) The ambient humidity should never exceed a 20 to 90% RH range.
(4) Do not install the unit in areas where condensation is likely to
occur (high humidity with extreme temperature changes).
(5) Avoid sites where dust is excessive.
(6) Do not install in areas with an excessive amount of salt and/or metal chips.
(7) Do not install in areas where flammable and/or corrosive gases are present.
(8) Avoid areas where splashing water, oil or chemicals are likely to occur.
(9) Avoid areas where vibration and shocks are excessive.
- Installation cautions
(1) Secure tightly with two pieces of M4 screws.
(2) Install as far from high voltage lines and power lines as possible in order to minimize noise influences.
(3) Allow 85mm or more space at the converter's front side for plugging in and unplugging the connector.
5-2. ABSOCODER Sensor Installation Conditions and Precautions
(1) Do not subject the sensor to excessive
shocks and unbalanced loads.
(2) If connected to a shaft, a coupling format
should be used.
For the installation conditions and precautions for ABSOCODER sensor, refer to “ABSOCODER HANDLING
PRECAUTION” (NSP-Z2022). This manual is available upon request.

6. WIRING
6-1. Connection between Converter and ABSOCODER Sensor
The cable connector is connected to the sensor connector
of the converter. The ABSOCODER sensor is equipped with
a 2-meter interconnecting sensor cable. If a longer length is
required, dedicated extension sensor cable must be used.
-Wiring Precautions
(1) The sensor cable should be clamped as shown
in the right figure to prevent excessive tension from
being applied to the cable connectors.
(2) The sensor cable should be located at least 300mm
away from power lines and other lines which generate
a high level of electrical noise.
(3) If the cable is moved under the state of bending
like a horseshoe, a robotic cable should be used.
The bend radius should never be less than 75 mm.
6-2. Power Supply Connection
The power supply should be connected as described below:
(1) Power Supply
- The rush current is 10A (rush time of 20ms), so
select the power supply after due consideration.
Choose the capacity of the power supply over
double of power consumption of converter.
- Use a power supply of 24VDC, and 8A or less.
- The input power supply should be isolated from
the commercial power supply.
- The power cable should be as thick as possible
to minimize voltage drops.
- Twist the power cable for preventing noises.
- Use the M3 size crimp lug terminals with
insulating sleeves in order to prevent short
circuit caused by loose screws. (Torque: 0.6N-m).
- Connect the power supply via a 4A (max.) over-current protection circuit.
(2) Ground
- The unit should be securely grounded (ground resistance of 100ohm or less) to prevent electrical shocks.
- The power cable should be as thick as possible.
