Maintenance parameters

4)Output of maintenance timer value (maintenance 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.

Maintenance timer value (H1)

x 5s (Maintenance timer value 100%/5s)

40000h

 

 

 

 

 

Note that the output time range is 2 to 9s, and

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 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.

2)the start bit is output as high pulse shape for 3.5s

invalid cycle(20s) next cycle

5) 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.

•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
