SAFETY PRECAUTIONS
Read the FT1A Series Pro/Lite User’s Manual to make sure of correct operation before starting installation, wiring, operation, maintenance, and
inspection of the SmartAxis.
All SmartAxis modules are manufactured under IDEC’s rigorous quality control system, but users must add a backup or failsafe provision to the
control system when using the SmartAxis in applications where heavy damage or personal injury may be caused in case the SmartAxis should
fail.
In this user’s manual, safety precautions are categorized in order of importance to Warning and Caution:
The SmartAxis is not designed for use in medical equipment, nuclear power, railways, aviation, passenger vehicle equipment, or similar
applications requiring a high degree of reliability and safety. The SmartAxis cannot be used for such applications.
When using the SmartAxis in applications not described above that require a high degree of reliability in terms of functionality and precision,
appropriate measures such as failsafe mechanisms and redundant mechanisms must be taken for the system containing the SmartAxis.
Emergency stop and interlocking circuits must be configured outside the SmartAxis.
If relays or transistors in the SmartAxis output circuits should fail, outputs may remain at on or off state. For output signals which may cause
serious accidents, configure monitor circuits outside the SmartAxis.
The SmartAxis self-diagnostic function may detect internal circuit or program errors, stop programs, and turn outputs off. Configure circuits so
that the system containing the SmartAxis is not jeopardized when outputs turn off.
Turn off power to the SmartAxis before installation, removal, wiring, maintenance, and inspection of the SmartAxis. Failure to turn power off
may cause electrical shocks or fire hazard.
Special expertise is required to install, wire, program, and operate the SmartAxis. People without such expertise must not use the SmartAxis.
Install the SmartAxis according to the instructions described in FT1A series Pro/Lite user's manual. Improper installation will result in falling,
failure, or malfunction of the SmartAxis.
The SmartAxis is designed for installation in a cabinet. Do not install the SmartAxis outside a cabinet.
Install the SmartAxis in environments described in FT1A series Pro/Lite user's manual. If the SmartAxis is used in places where the SmartAxis is
subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive vibrations, and excessive shocks, then electrical shocks,
fire hazard, or malfunction will result.
The environment for using the SmartAxis is “Pollution degree 2.” Use the SmartAxis in environments of pollution degree 2 (according to IEC
60664-1).
Prevent the SmartAxis from falling while moving or transporting the SmartAxis, otherwise damage or malfunction of the SmartAxis will result.
Wiring must use lead sizes that are appropriate for the applied voltage and current. Terminal screws must be tightened with the prescribed
tightening torque.
Prevent metal fragments and pieces of wire from dropping inside the SmartAxis housing. Put a cover on the SmartAxis modules during
installation and wiring. Ingress of such fragments and chips may cause fire hazard, damage, or malfunction.
Use a power supply of the rated value. Use of a wrong power supply may cause fire hazard.
Use an IEC 60127-approved fuse on the power line outside the SmartAxis. This is required when equipment containing the SmartAxis is destined
for Europe.
Use an IEC 60127-approved fuse on the output circuit. This is required when equipment containing the SmartAxis is destined for Europe.
Use an EU-approved circuit breaker. This is required when equipment containing the SmartAxis is destined for Europe.
Make sure of safety before starting and stopping the SmartAxis or when operating the SmartAxis to force outputs on or off. Incorrect operation
on the SmartAxis may cause machine damage or accidents.
Do not connect the ground wire directly to the SmartAxis. Connect a protective ground to the cabinet containing the SmartAxis using an M4 or
larger screw. This is required when equipment containing the SmartAxis is destined for Europe.
Do not disassemble, repair, or modify the SmartAxis modules.
The SmartAxis contains electronic parts and batteries. When disposing of the SmartAxis, do so in accordance with
national and local regulations.
Warning notices are used to emphasize that improper operation may cause severe personal injury or death.

Create Ladder Program
This section describes the procedure for creating a simple ladder program in WindLDR.
Note: See “INSTRUCTIONS REFERENCE” on page 4-1 for details on basic and advanced instructions.
Sample User Program
Create a simple program using WindLDR. The sample program performs the following operation:
When only input I0 is turned on, output Q0 is turned on.
When only input I1 is turned on, output Q1 is turned on.
When both inputs I0 and I1 are turned on, output Q2 flashes in 1-sec increments.
Note: One collection of a group of instructions that control output or advanced instructions is called a rung. WindLDR manages programs in rung
units. Function descriptions can be configured as rung comments for individual rungs.
Start WindLDR
From the Start menu of Windows, select Programs > Automation Organizer > WindLDR > WindLDR.
WindLDR starts and a blank ladder editing screen appears with menus and tool bars shown on top of the screen.
Rung No. Input I0 Input I1 Output Operation
1ON OFF Output Q0 is turned ON.
2OFF ON Output Q1 is turned ON.
3ON ON Output Q2 flashes in 1-sec increments.

6. Enter I1 in the Tag Name field, and click OK.
A NC contact of input I1 is programmed in the second column of the first ladder line.
At the end of the first ladder line, program the OUT instruction by inserting a NO coil of output Q0.
7. From the WindLDR menu bar, select Home > Basic > OUT (Output).
8. Move the mouse pointer to the third column of the first ladder line where you want to insert an output coil, and click the left
mouse button.
Note: Another method to insert an instruction (either basic or advanced) is to type the instruction symbol, OUT, where you want to insert the
instruction.
The Output dialog box appears.
9. Enter Q0 in the Tag Name field, and click OK.
A NO output coil of output Q0 is programmed in the right-most column of the first ladder line. This completes programming for
rung 1.
Continue programming for rungs 2 and 3 by repeating similar procedures.
A new rung is inserted by pressing the Enter key while the cursor is on the preceding rung. A new rung can also be inserted by
selecting Home > Append > Append a Rung.

3: DEVICE ADDRESSES
Introduction
This chapter describes device addresses available for the SmartAxis to program basic and advanced instructions. Special internal
relays and special data registers are also described.
The SmartAxis is programmed using devices such as inputs, outputs, remote inputs, remote outputs, internal relays, timers,
counters, shift registers, and data registers.
Inputs (I) are relays to receive input signals through the input terminals.
Remote inputs (I) are relays to receive input signals from external devices connected to the remote I/O slaves.
Outputs (Q) are relays to send the processed results of the user program to the output terminals.
Remote outputs (O) are relays to send output signals to external devices connected to the remote I/O slaves.
Internal relays (M) are relays used in the CPU and cannot be outputted to the output terminals.
Special internal relays (M) are internal relays dedicated to specific functions.
Timers (T) are relays used in the user program, available in 1-sec, 100-ms, 10-ms, and 1-ms timers.
Counters (C) are relays used in the user program, available in adding counters and reversible counters.
Shift registers (R) are registers to shift the data bits according to pulse inputs.
Data registers (D) are registers used to store numerical data.
Special data registers (D) are dedicated to special functions.
Device Addresses
Available I/O numbers depend on the type of the SmartAxis CPU module.
Notes:
The least significant digit of input, output, internal relay, and special internal relay device address is an octal number (0 through 7). Upper
digits are decimal numbers.
Out of data registers D0 through D1999, D1000 through D1999 cannot be designated as "keep" types. Retained in STOPRUN, but zeroed
out when the power is turned on.
