CHAPTER 6 - DETAILED PARAMETER DESCRIPTION
Notesabout the functions of the relayoutputs:
1)
When the definition in the function name is true, the
digital output will be activated, i.e., the relay coil is
energized.
2)
When the option 'Not used' has been programmed,
the relayoutput(s) will be disabled, i.e., the coil is not
energized.
3)
CFW-08 Plus has 2 relay outputs (1 NO and 1 NC
contact). It is possible to emulate a reversal contact
relay by setting P277 = P279.
Definitions of the symbols used in the functions:
-
Fs
= P005 - Motor Output Frequency
-
Fe
= FrequencyReference (ramp input frequency)
-
Fx
= P288 - Fx Frequency
-
Is
= P003 - Motor Output Current
-
Ix
= P290 - Ix Current
