L4 Reference Detection - YASKAWA VS-616G5 Series Programming Manual

L4 Reference Detection
The VS-616G5 utilizes three different functions for detecting output frequency:
· When frequency agree is enabled at the multi-function contact outputs (H2-__ = "2" or "13"), the
contact closes whenever the output frequency "agrees" with the frequency reference, plus or minus
the speed agree detection width.
· When desired frequency agree is enabled at the multi-function contact outputs (H2-__ = "3" or
"14"), the contact closes whenever the output frequency "agrees" with the speed agree detection
level, plus or minus the speed agree detection width.
· When frequency detection is enabled at the multi-function contact outputs (H2-__ = "4", "5", "15"
or "16"), the contact closes whenever the output frequency is less than or more than the speed agree
detection level, depending on which detection is selected.
Refer to section H2, Digital Outputs on page 88, for more detailed information on setting these func-
tions.
L4-01 Speed Agree Detection Level (without sign)
Setting Range:
Factory Default:
Sets the detection level for the desired frequency agree 1 and frequency detection 1 and 2 functions.
The set detection level is effective during both FWD and REV operation.
L4-02 Speed Agree Detection Width
Setting Range:
Factory Default:
Sets the detection width for frequency and desired frequency agree 1 and frequency detection 1 and 2 func-
tions.
L4-03 Speed Agree Detection Level (with sign)
Setting Range:
Factory Default:
Sets the detection level for the desired frequency agree 2 and frequency detection 3 and 4 functions.
The set detection level is effective during either FWD or REV operation, depending on the set detec-
tion level (positive value for FWD operation, negative value for REV operation).
L4-04 Speed Agree Detection Width
Setting Range:
Factory Default:
Sets the detection width for frequency and desired frequency agree 2 and frequency detection 3 and 4 func-
tions.
