Electric Shock Prevention
Incorrect handling may cause hazardous conditions, resulting in death or severe injury.
Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material
damage.
Warning
While the inverter power is ON, do not open the front cover or the wiring cover. Do not run the inverter with the front cover or the wiring cover removed. Otherwise
you may access the exposed high voltage terminals or the charging part of the circuitry and get an electric shock.
Do not remove the inverter front cover even if the power supply is disconnected. The only exception for this would be when performing wiring and periodic
inspection. You may accidentally touch the charged inverter circuits and get an electric shock.
Before wiring or inspection, LED indication of the inverter unit operation panel must be switched OFF. Any person who is involved in wiring or inspection shall wait
for at least 10 minutes after the power supply has been switched OFF and check that there is no residual voltage using a tester or the like. For some time after the
power-OFF, a high voltage remains in the smoothing capacitor, and it is dangerous.
Any person who is involved in wiring or inspection of this equipment shall be fully competent to do the work.
The plug-in option must be installed before wiring. Otherwise you may get an electric shock or be injured.
Do not touch the plug-in option or handle the cables with wet hands. Otherwise you may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric shock.
Injury Prevention
Caution
The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise a burst, damage, etc. may occur.
The cables must be connected to the correct terminals. Otherwise a burst, damage, etc. may occur.
The polarity (+ and -) must be correct. Otherwise a burst or damage may occur.

• If 0 to 5 V (0 to 10 V) is input at the inverter terminal 1 from the external potentiometer with the FR-A8AX installed, the
inverter operates at the frequency obtained by adding the FR-A8AX BCD code input and the compensation input from
terminal 1 only when "2, 3, 12, 13" is set in Pr.304.
For example, when switching the inputs to perform manual operation with potentiometer input or automatic operation

Torque command may be input in either of the following two ways:
Set the torque commands at 0 and
H7FFF (H7FF) signal inputs
Set the torque command value when the input
signal is "0" in Pr.447 and the torque command
value when the input signal is "H7FFF (H7FF) in
Pr.448.
The figure on the right shows the case when the
torque command value is set using input signal
H7FFF (H7FF) when the torque command value is
150% (initial value of Pr.448). When the most
significant bit of input signal is positive, a negative
torque command value (-150%) is also set at the
same time.
Use the digital input value as the
torque command
When "9999" is set in Pr.448, the input signal is considered as a torque command value.
For example, the torque command value when the input signal is H190 is 400%, as shown below.
Even if a value higher than H190 is input, the torque command value is clamped at 400%.

4.3Precautions
• Acceleration/deceleration time
When the frequency is set with the digital input signal, the acceleration/deceleration time is the period of time required to
reach Pr.20 Acceleration/deceleration reference frequency.
• The following restrictions are applied on the digital input signal:
When one of H0A to H0F is input to each digit while BCD code input is set, the operation is performed with the inputs
previous to H0A to H0F. H0A to H0F inputs are ignored.
If binary input is changed to BCD code input while H0A to H0F are being input, the set frequency becomes 0 Hz.
• The priorities of the frequency setting are as follows:
JOG > Stop-on contact (RT, RL) > Multi-speed command (RH, RM, RL) > PID (X14) > AU (terminal 4) > Pulse train input >
Digital command by the FR-A8AX > terminal 2
When digital input is valid, terminal 2 is invalid.
