Dancer feedback speed control details
64
• The line speed commanded by pulse train input is calibrated with
Pr.351 Line speed command bias
,
Pr.353 Line speed
command gain
,
Pr.354 Line speed command pulse input bias
, and
Pr.355 Line speed command pulse input gain
.
The calculation result is applied as the line speed command value (lower limit: 0 m/min, upper limit: 6553.4 m/min). When
Pr.353
= "9999", the calculation result is invalid (line speed command value: 0).
NOTE
• To input the line speed command by the pulse train input to the plug-in option or control terminal option under vector control,
setting of
Pr.862 Encoder option selection
is required. (Refer to
Line speed command analog input (Pr.361 = "3 to 6")
• The line speed can be commanded by analog input.
• The line speed commanded by analog input is calibrated with
Pr.350 Line speed command voltage/current bias
,
Pr.351
Line speed command bias
,
Pr.352 Line speed command voltage/current gain
, and
Pr.353 Line speed command
gain
. The calculation result is applied as the line speed command value (lower limit: 0 m/min, upper limit: 6553.4 m/min).
When
Pr.353
= "9999", the calculation result is invalid (line speed command value: 0).
• When the line speed is commanded by analog input, the input value can be filtered using
Pr.74 Input filter time constant
,
Pr.822 Speed setting filter 1
, and
Pr.832 Speed setting filter 2
.
NOTE
• The difference between the setting values of
Pr.350
and
Pr.352
can be set within 5%. (Even if the difference is 5% or less,
Er3 (calibration error) does not occur.)
• The
Pr.350
setting can be larger than the
Pr.352
setting. Also, the
Pr.351
setting can be larger than the
Pr.353
setting.
