Maintenance function
4) Output of maintenance timer value (additional parameter H1)
After the output current average value is output as low pulse shape, the
maintenance timer value is output as high pulse shape. The output time of the
maintenance timer value is obtained from the following calculation.
Refer to
(page 101).

Note that the output time range is 2 to 9s, and
it is 2s when the maintenance timer value (H1)
is less than 16000h and 9s when exceeds
72000h.
REMARKS
•
Mask of data output and sampling of output current are not performed during acceleration/
deceleration.
•
Set "93" in Pr. 64 and assign the current average value monitor signal (Y93) to the RUN
terminal. It can not be assigned to the ABC contact (Pr. 65)
•
When the speed is changed to acceleration/deceleration from constant speed during start
pulse output, the data is judged as invalid, the start pulse is output as high pulse shape for
3.5s, and the end pulse 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 pulse output is completed.
•
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.
(1) when the motor is in the acceleration/deceleration state on completion of the 1 cycle
signal output
(2) when the 1 cycle output is completed during restart operation with automatic restart after
instantaneous power failure (Pr. 57
≠
"---")
(3) when automatic restart operation was being performed with automatic restart after
instantaneous power failure selected (Pr. 57
≠
"---") on completion of the data output mask
