L4 Reference Detection

L4 Reference Detection
The VS-616PS5 utilizes three different functions for detecting output speed:
• When speed agree is enabled at the multi-function contact outputs (H2-__ = "2" or
"13"), the contact closes whenever the output speed "agrees" with the speed refer-
ence, plus or minus the speed agree detection width.
• When desired speed agree is enabled at the multi-function contact outputs (H2-__ =
"3" or "14"), the contact closes whenever the output speed "agrees" with the speed
agree detection level, plus or minus the speed agree detection width.
• When speed detection is enabled at the multi-function contact outputs (H2-__ = "4",
"5", "15" or "16"), the contact closes whenever the output speed is less than or more
than the speed agree detection level, depending on which detection is selected.
Refer to section H2, Digital Outputs, for more detailed information on setting these
functions.
L4-01 Speed Agree Detection Level (without sign)
Setting Range:
Factory Default:
Sets the detection level for the desired speed agree 1 and speed detection 1 & 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 speed agree 1 and speed detec-
tion 1 & 2 functions.
L4-03 Speed Agree Detection Level (with sign)
Setting Range:
Factory Default:
Sets the detection level for the desired speed agree 2 and speed detection 3 & 4
functions. The set detection level is effective during either FWD or REV operation,
depending on the set detection level (positive value for FWD operation, negative
value for REV operation).
