Precautions

• Acceleration/deceleration time
When the digital input signal is set as the frequency, the acceleration/deceleration time is the period of time required to reach
Pr.20 Acceleration/deceleration reference frequency, in the same way when the analog input signal is set.
• 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
Note that terminal 2 is invalid when the digital input is enabled.
