Useful functions
NOTES
Mask of data output and sampling of output current are not performed during acceleration/
deceleration.
When the speed is changed to acceleration/deceleration from constant speed during start bit
output, the data is judged as invalid, the start bit is output as high pulse shape for 3.5s, and
the end signal is output as low pulse shape for 16.5s. The signal is output for at least 1 cycle
even when acceleration/deceleration state continues after the start bit output is completed.
Output frequency
When the output current value (inverter output current monitor) is 0A on completion of the 1
cycle signal output, the signal is not output until the speed becomes constant next time.
The current average value monitor signal (Y93) is output as low pulse shape for 20s (without
data output) under the following condition:
When the motor is in the acceleration/deceleration state on completion of the 1 cycle
signal output.
When 1-cycle signal output was ended during restart operation with the setting of
automatic restart after instantaneous power failure (Pr. 57 ≠ 9999).
When automatic restart operation was being performed with automatic restart after
instantaneous power failure selected (Pr. 57 ≠ 9999) on completion of the data output
mask.
When terminal assignment is changed using Pr. 190 to Pr. 192 "Output terminal function
selection", the other functions may be affected. Please make setting after confirming the
function of each terminal.
