This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect this product until you have read through this instruction man-
ual and appended documents carefully and can use the equipment correctly. Do not use this product until you have
a full knowledge of the equipment, safety information and instructions.
In this instruction manual, the safety instruction levels are classified into "WARNING" and "CAUTION".
Assumes that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
Assumes that incorrect handling may cause hazardous conditions, resulting in
medium or slight injury, or may cause physical damage only.
Note that the CAUTION level may lead to a serious consequence according to conditions. Please follow the instruc-
tions of both levels because they are important to personnel safety.
SAFETY INSTRUCTIONS
!While power is on or when the inverter is running, do not open the front cover. You may get an electric shock.
!Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage termi-
nals and charging part and get an electric shock.
!If power is off, do not remove the front cover except for wiring or periodic inspection. You may access the
charged inverter circuits and get an electric shock.
!Before starting wiring or inspection, switch power off, wait for more than 10 minutes, and check for no residual
voltage with a tester or the like.

2.INSTALLATION
2.1 Pre-Installation Instructions
Make sure that the input power of the inverter is off.
2.2 Installation Procedure
(1) Securely insert the connector of the option unit far into the connector of the inverter. At this time, fit the
option fixing holes snugly. For the position of slot, refer to the next page.
Also be sure to fit the unit into the option fixing hook (For the FR-A500(L)/ FR-F500(L) series, it is avail-
able in Aug., 2000).
(2) Securely fix the option unit to the inverter on both sides with the accessory mounting screws. If the
screw holes do not match, the connector may not have been plugged snugly. Checkfor loose plugging.
With input power on, do not install or remove the option unit. Otherwise, the inverter and
option unit may be damaged.

INSTALLATION
CAUTION
1. Only one type of option per inverter may be used. When two or more options are mounted, pri-
ority is in order of slots 1, 2 and 3, the options having lower priority are inoperative.
2. When the inverter cannot recognize that the option is
mounted, it displays the option error. The errors shown
differ according to the mounting slots 1, 2, 3.

INSTALLATION
2.3 Wiring
Route the wires so that they do not take up a lot of space in the control circuit terminal block of the option unit.
During wiring, do not leave wire off-cuts in the inverter. They may cause a fault, failure or malfunction.
Use the space on the left side of the control circuit terminal unit to route the wires.
REMARKS
The wires with large gaze may not be connected to the terminal block. When connected in parallel, all wires may not
fit in the wiring space due to the increased number of wires. In such cases, perform wiring by using a junction termi-
nal block.
When installing the inverter front cover, the cables to the inverter's control circuit terminals
and option terminals should be routed properly in the wiring space to prevent them from
being caught between the inverter and its cover.

REMARKS
1. As the input signals are at low level, use two parallel micro signal contacts or a twin contact for relay contact
inputs to prevent a contact fault.
2. A transistor of the following specifications should be selected for the open collector signal: Electrical characteris-
tics of the transistor used

changed to source, the option logic also switches to source. For details on changing the control logic, refer to the
inverter instruction manual.

12-BIT DIGITAL INPUT
3.2 Terminals
Terminal Symbol Description
X0 to X11 Digital signal input terminals (frequency/speed setting signal terminals) Used to input a 3-digit BCD (999 maximum) (refer to page 6) or 12-bit binary (FFFH maxi-
mum) relay contact or open collector signal.
DY
Data read timing input signal
Used when a digital signal read timing signal is necessary.
Data is only read while the DY signal is on.
By switching the DY signal off, the X0 to X11 data before signal-off is retained. (Refer to page
12.)
SD Common terminal (sink) Common terminal for digital and data read timing signals.
This terminal is the SD terminal of the inverter.
PC
External transistor common terminal (source)
When connecting the transistor output (open collector output) of a programmable controller
(PC), etc., connect the external power common (+) to this terminal to prevent a fault occurring
due to leakage current. When you have selected the source logic, this terminal is used as a
common terminal. This terminal is the PC terminal of the inverter.

The set frequency data (set speed data) entered from the digital signal input terminals is imported
only when the DY signal is on. The set frequency data (set speed data) is not imported when the DY
signal is off. Therefore, if the input status of the X0-X11 signal changes, the set frequency data (set
speed data) before off of the DY signal is valid.

(4) Gain adjustment [Pr.301], [Pr.303]
The gain may be set in either of the following two ways:
!How to set the output frequency at the input signal of 999 (BCD code) or FFFH (binary)
(The factory setting is 60Hz (1500r/min. for the FR-V500 series) for this input signal. )
!How to set the BCD code or binary value as the output frequency (output speed) setting
When "9999" isset in Pr.301(BCD code) or Pr.303 (binary), thedigital input value is set(unchanged)
as the output frequency (output speed).
(For example, to set the output frequency to 120Hz at the BCD code input of "120")
CAUTION
The maximum output frequency (maximum operation speed) for operation with the digital input is
the "gain" value set in Pr.301 and Pr.303.
To set the maximum output frequency to 60Hz or more with the FR-A500(L)/F500(L) series and the
maximum operation speed to 1500r/min or more with the FR-V500 series, change the "gain" from
