16. (G) Control Parameters
16.8 Regenerative brake selection
• Relationship between
Pr.17
and the Inverter run enable signal of each option unit
NOTE
• When
Pr.30
= "0 or 2" and the X10 signal is not assigned to an input terminal, the MRS signal can be used as the X10 signal.
The logic of the signal depends on that of the MRS signal (normally open input when
Pr.17
= "0 or 1", and normally closed
input when
Pr.17
= "2 to 5").
• The MRS signal is valid regardless of whether it is input through the external terminal or via network (except for the FR-E800-
SCE), but when the MRS signal is used as the Inverter run enable (X10) signal, input the signal through the external terminal.
• When the terminal assignment is changed with
Pr.178 to Pr.184 (Input terminal function selection)
, wiring may be mistaken
due to different terminal name and signal contents, or may affect other functions. Set parameters after confirming the function
of each terminal.
Regenerative brake duty warning output and the warning signal (RBP
signal)
• When the regenerative brake duty reaches 85% of the
Pr.70
setting, "RB" is indicated on the operation panel and the
Regenerative brake prealarm signal (RBP) signal is output. When it reaches 100% of the
Pr.70
setting, it will become
regenerative overvoltage (E.OV[]).
• The inverter output is not shut off with the warning signal.
• For the terminal to be used for the RBP signal output, set "7" (positive logic) or "107" (negative logic) to one of
Pr.190 to
Pr.196 (Output terminal function selection)
, and assign the function.
100%: Regeneration overvoltage protection operation value
NOTE
• When
Pr.30
= "0" (initial value), "RB" is not indicated.
• Changing the terminal assignment using
Pr.190 to Pr.196 (Output terminal function selection)
may affect the other
functions. Set parameters after confirming the function of each terminal.
Connection of a brake resistor other than the FR-ABR, MRS type, and
MYS type
A brake resistor can be used with the FR-E820-0030(0.4K) or higher, FR-E840-0016(0.4K) or higher, FR-E860-0017(0.75K)
or higher, and FR-E820S-0030(0.4K) or higher.
