When using the provided brake resistor, or the brake unit (FR-A860-
01080 or lower)
• When using the provided brake resistor or the brake unit, set Pr.30 = "0 (initial value), 10, 20, 100, 110, 120". Setting of
Pr.70 will become disabled.
At this time, the regenerative brake duty is as follows.
• FR-A860-00090 or lower ......................................... 2%
• Other than above ..................................................... 0%
NOTE
• The brake resistor is provided with the FR-A860-00090 or lower.
When using the brake resistor other than the provided brake resistor
(FR-A860-01080 or lower)
• Set Pr.30 = "1, 11, 21".
• Set Pr.70 as follows.
FR-A860-00170 or lower .................................................................................10%
FR-A860-00320 or higher ................................................................................6%
When using the converter unit (FR-CC2) (separated converter type)
• When using FR-CC2, set Pr.30="10" (initial value of separated converter type).
• Assign the following signal to a contact input terminal using any of Pr.178 to Pr.189 (Input terminal function selection).
(a) Inverter run enable signal (X10): FR-CC2 connection
To have coordinated protection with FR-CC2, shutoff the inverter output by the X10 signal.
Input the RDA signal of FR-CC2.
(b) FR-CC2 connection, instantaneous power failure detection signal (X11): FR-CC2 connection
During the operation using RS-485 communication, with the remote output and analog remote output functions
enabled, the X11 signal is used to store the status when the inverter is set to store the status before an
instantaneous power failure.
Input the IPF signal (instantaneous power failure detection signal) of the FR-CC2.
• For the terminal to be used for the X10 and X11 signal, set "10" (X10), "11" (X11) in Pr.178 to Pr.189 and assign the
function. (For separated converter types, the X10 signal is assigned to the terminal MRS in the initial setting.)
Logic reversing of inverter run enable signal (X10 signal, Pr.599)

(Initial value)
• Use Pr.599 X10 terminal input selection to select the X10 signal input
Motor coasts to stop
specification between normally open (NO contact) and normally closed
(NC contact). With the normally closed (NC contact) input specification,
the inverter output is shut off by turning OFF (opening) the X10 signal.
• Changing the inverter logic (NO/NC contact) with the Pr.599 setting is
required according to the logic of the inverter operation enable signal
