<Setting>

Perform setting according to the following steps.

1)Setting of maintenance parameter H4 "data output mask time"

The output current is unstable (transient state) right after the operation is changed from the acceleration/deceleration state to the constant speed operation. Set the time for not obtaining (mask) transient state data in H4.

2)Setting of maintenance parameter H3 "output current average time"

The average output current is calculated during Hi output of start bit (1s). Set the time taken to average the current during start bit output in H3.

3)Setting of maintenance parameter H5 "output reference current"

Set the reference (100%) for outputting the signal of the current average value. Obtain the time to output the signal from the following calculation.

Output current average value x 5s (Output current average value 100%/5s) Setting value of output reference current (H5)

Note that the output time range is 0.5s to 9s, and it is 0.5s when the output current average value is less than 10% of the setting value of output reference current (H5) and 9s when exceeds 180%. Example) when H5=10A and the average value of

output current is 15A

As 15A/10Ax5s=7.5, the current average value monitor signal is output as low pulse shape for 7.5s.
