NOTE
• Masking of the data output and sampling of the output current are not performed during acceleration/deceleration.
• If constant speed changes to acceleration or deceleration during start pulse output, it is judged as invalid data, and HIGH
output in 3.5 seconds intervals is performed for the start pulse and LOW output in 16.5 seconds intervals is performed for the
end signal. After the start pulse output is completed, minimum 1-cycle signal output is performed even if acceleration/
deceleration is performed.
Start pulse
Output as high pulse shape for 3.5 s
• If the output current value (inverter output current monitor) is 0 A at the completion of the 1-cycle signal output, no signal is
output until the next constant-speed state.
• Under the following conditions, the Y93 signal is output with LOW output in 20 seconds intervals (no data output).

• Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
