4-1 Location for installation
The NETC01-M2 has been designed and manufactured for use as a component to be installed inside equipment.
Install it in a well-ventilated location that provides easy access for inspection. The location must also satisfy the
following conditions:
•Inside an enclosure that is installed indoors (provide vent holes)
•Operating ambient temperature 0 to +40 °C (+32 to +104 °F) (non-freezing)
•Operating ambient humidity 85% or less (non-condensing)
•Area that is free of explosive atmosphere or toxic gas (such as sulfuric gas) or liquid
•Area not exposed to direct sun
•Area free of excessive amount of dust, iron particles or the like
•Area not subject to splashing water (rain, water droplets), oil (oil droplets) or other liquids
•Area free of excessive salt
•Area not subject to continuous vibration or excessive shocks
•Area free of excessive electromagnetic noise (from welders, power machinery, etc.)
•Area free of radioactive materials, magnetic elds or vacuum
4-2 Installation method
Install the NETC01-M2 to a 35 mm (1.38 in.) width DIN rail.
There must be a clearance of at least 50 mm (1.97 in.) in the horizontal
and vertical directions, between the NETC01-M2 and enclosure or
other equipment within the enclosure.
When installing two or more NETC01-M2 in parallel, it is possible to
install them closely in the horizontal direction. Provide a minimum
clearance of 50 mm (1.97 in.) in the vertical direction.
50 mm (1.97 in.)
or more
50 mm (1.97 in.)
or more
Be sure to install the NETC01-M2 vertically (vertical

Removing from DIN rail
Pull the DIN lever down until it locks using a slotted screwdriver, and lift the bottom of
the NETC01-M2 to remove it from the rail.
Use force of about 10 to 20 N (2.2 to 4.5 lb.) to pull the DIN lever to lock it. Excessive
force may damage the DIN lever.
4-3 Installing and wiring in compliance with EMC Directive
Eective measures must be taken against the EMI that the NETC01-M2 may give to adjacent control-system
equipment, as well as the EMS of the NETC01-M2 itself, in order to prevent a serious functional impediment in the
machinery. The use of the following installation and wiring methods will enable the NETC01-M2 to be compliant
with the EMC Directive. Refer to “CE Marking” on p.5 for the applicable standards.
Oriental Motor conducts EMC measurements on its NETC01-M2 in accordance with“Example of NETC01-M2
installation and wiring”on p.10. The user is responsible for ensuring the machine’s compliance with the EMC
Directive, based on the installation and wiring explained below.
Power supply
This network converter is a product of DC power supply input.
Use a DC power supply (switching power supply etc.) that conforms to the EMC Directive.
Noise lter
•Connect a noise lter in the DC power supply input to prevent the noise generated in the NETC01-M2 from
propagating externally through the power supply line.
•When using a power supply transformer, be sure to connect a noise lter to the AC input side of the power supply
transformer.
•For a noise lter, use HF2010A-UPF (SOSHIN ELECTRIC CO., LTD), FN2070-10-06 (Schaner EMC) or equivalent
product.
•Install the noise lter as close to the AC input terminal of DC power supply as possible. Use cable clamps and other
means to secure the AC input cables (AWG18: 0.75 mm2or more) and output cables (AWG18: 0.75 mm2or more)
rmly to the surface of the enclosure.
•Connect the ground terminal of the noise lter to the grounding point, using as thick and short a wire as possible.
•Do not place the AC input cable parallel with the noise lter output cable. Parallel placement will reduce noise lter
eectiveness if the enclosure’s internal noise is directly coupled to the power supply cable by means of stray
capacitance.
How to ground
The cable used to ground the NETC01-M2 and mains lter must be as thick and short as possible so that no
potential dierence is generated. Choose a large, thick and uniformly conductive surface for the grounding point.
Wiring the power supply cable and I/O signal cable
•Use a shielded cable of AWG22 (0.3 mm2) or more for the power supply cable of the NETC01-M2, and keep it as
short as possible.
•For the MECHATROLINK-II communication cable, use a dedicated cable with connector.
•To ground the power supply cable , use a metal cable clamp or
similar device that will maintain contact with the entire
circumference of the cable. Attach a cable clamp as close to the end
of the cable as possible, and connect it as shown in the gure.

Shielded cable

Installation

Notes about installation and wiring
•Connect the NETC01-M2 and other peripheral control equipment directly to the grounding point so as to
prevent a potential dierence from developing between grounds.
•When relays or electromagnetic switches are used together with the system, use noise lters and CR circuits to
suppress surges generated by them.
•Keep cables as short as possible without coiling and bundling extra lengths.
•Place the power cables such as the motor and power supply cables as far as 100 mm (3.94 in.) from the signal
cables. If the power cables and signal cables have to cross, cross them at a right angle. Place the AC input cable and
output cable of a noise lter separately from each other.

STEP 4 Set the parameters of CRD-KD
Set the parameters of the CRD-KD using any of the MEXE02, OPX-2A, RS-485 communication or MECHATROLINK-II
communication.
1. Set the “START input mode (1C00h)” parameter of the CRD-KD to “0: RS-485 communication.”
(Initial setting: I/O)
2. Set the position (travel amount: 1001h) and operating speed (1101h) to the operation data No.1 of the CRK-KD.
3. Set the “Data No. input mode (1C0Dh)” parameter of the CRD-KD to“0: RS-485 communication.”
(Initial setting: I/O)
4. Set the “STOP contact conguration (1C03h)”parameter of the CRD-KD to “0: Normally open.”
(Initial setting: Normally closed)
•Operation data or parameters set via RS-485 communication or MECHATROLINK-II communication
will be written to the RAM of the CRD-KD. The data stored in the RAM will be erased when turning
o the power supply of the CRD-KD. When saving the data to the non-volatile memory, execute
the "Batch NV memory write" command of the maintenance command.
•The operation data or parameters set by the MEXE02 or OPX-2A will be saved to the non-volatile
memory of the CRD-KD.
•The non-volatile memory can be rewritten approx. 100,000 times.
STEP 5 Execute positioning operation
Control the I/O signal of the CRD-KD using the I/O command (DATA_RWA: 50h) of MECHATROLINK-II communication.
1. Select the data No.1 by turning the M0 of the address number 0 to ON.
2. Execute positioning operation by turning the START of the address number 0 to ON.
STEP 6 Were you able to operate the motor properly?
How did it go? Were you able to operate the motor properly? If the motor does not function, check the following
points:
•Is any alarm present in the NETC01-M2 or CRD-KD?
•Are the address number, transmission rate and termination resistor set correctly?
•Are the“Connection” parameters of the NETC01-M2 set correctly?
•Is the C-ERR LED lit? (RS-485 communication error)
•Is the ERR LED lit? (MECHATROLINK-II communication error)
•Is the operation data set correctly?
•Is the motor for the CRD-KD excited? Or is the excitation setting correct?
•Are the CRD-KD parameters set correctly?
•Is the STOP input of the CRD-KD I/O turned ON?

Be sure to turn o the NETC01-M2 power before setting the switches. If the switches are set while
the power is still on, the new switch settings will not become eective until the NETC01-M2 power
is cycled.
7-1 Transmission rate of RS-485 communication
Set the transmission rate using the transmission rate setting switch (SW1).
Factory setting 7 (625 kbps)
•For the SW1, always set to "7." If the switch is set to the dial of "8" or higher, the communication
switch setting error alarm will be generated when turning on the power. And do not set the switch
to the dial of "0" to "6" because they cannot be used. (An alarm will not be generated.)
•For the transmission rate of the RS-485 communication compatible product, set to 625 kbps.
7-2 Operation mode
Set the remote I/O occupied size and number of transmission bytes for the RS-485 communication compatible
product connecting to a NETC01-M2. Set the remote I/O occupied size using the operation mode setting switch
SW2-No.1, and set the number of transmission bytes using the SW2-No.2 and No.3.
If the operation mode is changed, cycle the power.
Factory setting No.1: OFF (Remote I/O occupied size: 16 bit mode)
No.2: OFF, No.3: ON (Number of transmission bytes: 32 bytes)
SW2 Description Factory setting
No.1
Sets the remote I/O occupied size.
OFF: 16 bit mode (Up to 8 units can be connected)
ON: 8 bit mode (Up to 16 units can be connected)
OFF
No.2
No.3
Set the number of transmission bytes.
No.2=OFF, No.3=OFF: 17 bytes
No.2=OFF, No.3=ON: 32 bytes
No.2: OFF
No.3: ON
The SW2-No.4 is not used.

7-3 Station address
Set the station address using the two MECHATROLINK-II station address setting switches (STATION No.×1 and ×10).
When connecting two or more MECHATROLINK-II compatible products, do not set duplicate station address.
Set the tens place with the “STATION No.×10” switch and the ones place with the“STATION No.×1” switch.
Setting range 60h to 7Fh
Factory setting 61h (×10: 6, ×1: 1)
00h to 5Fh and 80h to FFh cannot be used.

This chapter explains the MECHATROLINK-II communication format that the NETC01-M2 supports.
8-1 Data format
The outline of the data format for MECHATROLINK-II communication is shown below. The NETC01-M2 is compatible
with the cyclic communication mode.
The cyclic communication mode of MECHATROLINK-II communication species that the header elds are 1 byte to
4 bytes and the data elds are 5 bytes and later.

8-2 Phase
The communication phases of MECHATROLINK-II communication are classied as follows.
Phase Description
0This is a state at power-on. When turning on the power for the master station and slave station,
operation switches to phase 1.
1 This is a state waiting for the connection establishment between the master station and slave station.
2Asynchronous communication between the master station and slave station is enabled. Only
asynchronous command can be used.
3Synchronous communication between the master station and slave station is enabled. Both
asynchronous command and synchronous command can be used.
4This is a state that the communication between the master station and slave station is stopped and the
connection is disconnected.
5 This is a state turning o the power for the master station and slave station.
