Maintenance parameters
<Pulse operation>
The output pulse of the Y93 signal is shown below.
<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.
Y93 signal
1 cycle (20s)
5) End pulse
Output as low pulse
shape for 1 to 16.5s
4) Maintenance timer pulse
The maintenance timer value (H1) is
output as high output pulse shape for 2 to
9s (16000h to 72000h).
Next cycle
Output frequency
From acceleration to constant speed operation
2) Start pulse
Output as high pulse shape for 1s (fixed)
Time and output current set in H3 are
averaged
1) Data output mask time
When the speed has changed
to constant from
acceleration/deceleration,
Y93 signal is not output
for H4 time.
3) Output current average value pulse
The averaged current value is output as
low pulse shape for 0.5 to 9s (10 to 180%)
during start bit output.
