2.1 Pre-Installation Instructions
Make sure that the input power of the inverter is off.
CAUTION
With input power on, do not install or remove the option unit. Otherwise, the inverter and
option unit may be damaged.
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 available 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. Check for loose plugging.

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.
Cable routing
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 terminal block.
CAUTION
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.
Micro signal contancts
Twin contancts
2. A transistor of the following specifications should be selected for the open collector signal: Electrical characteristics of the transistor used
• Ic ≥ 10mA
•Leakage current: 100µ
µA maximum
•VCE ≥ 30V
• If Ic ≥ 10mA, VCE (sat) voltage is 3V maximum
3. The control logic is the same as that of the inverter (factory-set to sink). When the logic of the inverter is
changed to source, the option logic also switches to source. For details on changing the control logic, refer to the
inverter instruction manual.

Description
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 maximum) relay contact or open collector signal.
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.)
Common terminal (sink)
Common terminal for digital and data read timing signals.
This terminal is the SD terminal of the inverter.
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 always

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

When the frequency is set with the digital input signal, the acceleration/deceleration time is the period
of time required to reach the "acceleration/deceleration reference frequency" set in Pr. 20. This is the
same as when using the analog signal input.
(2) There are the following restrictions on the digital input signal:
• When the signal is used to enter a BCD code, 0AH to 0FH entries are ignored during operation and
the previous inputs are used to continue operation.

invalid.

in Pr. 304.
When switching the inputs e.g. between volume input to perform manual operation and BCD code input
