Function:
These parameters can be read out via the serial communi-
cation port and the LCP display. See also parameters
009-012 Display readout.
Description of choice:
Parameter 515 Resulting reference %:
Gives the resulting reference as a percentage in the range
from minimum reference, Ref
Ref . See also Dealing with references.
MAX
Parameter 516 Resulting reference [unit]:
Gives the resulting reference in Hz in open loop (parameter
100). In a closed loop, the reference unit is selected in
parameter 416 Process units.
Parameter 517 Feedback [unit]:
Gives the resulting feedback value with the unit/scaling
selected in parameter 414 Minimum feedback, parameter
415 Maximum feedback and parameter 416 Process units.
See chapter 4.3.1 Handling of References for more details.
Parameter 518 Frequency [Hz]:
Gives the output frequency from the adjustable frequency
drive.
Parameter 519 Frequency x scaling [-]:
