Mitsubishi Electric FR-A800 Series Instruction Manual page 728

• Set Pr.70 = 0% (initial value).
• Set the brake unit FR-BU2, Pr.0 Brake mode selection = "2".
NOTE
• The stall prevention (overvoltage), oL, does not occur while Pr.30 = "1, 11, or 21".
 When using the power regeneration converter (MT-RC)
• Set "1 or 101" in Pr.30.
• Set Pr.70 = 0% (initial value).
 When using the high power factor converter (FR-HC2), multifunction
regeneration converter (FR-XC), power regeneration common converter
(FR-CV), or converter unit (FR-CC2)
• To use the FR-HC2 or FR-CV, set Pr.30 = "2 or 102". The Pr.70 setting is invalid.
• To use the FR-XC in common bus regeneration mode, set Pr.30 = "2 or 102".
• To use the FR-XC in power regeneration mode, set Pr.30 = "0 or 100".
• When using the FR-CC2, set Pr.30 = "10" (initial value of the separated converter type).
• Use any of Pr.178 to Pr.189 (Input terminal function assignment) to assign the following signals to the contact input
terminals.
(a) Inverter run enable (X10) signal: FR-HC2 connection, FR-XC connection, FR-CV connection, FR-CC2 connection
To ensure coordinated protection of the FR-HC2, FR-XC (common bus regeneration mode), FR-CV, or FR-CC2, use
the X10 signal to shut off the inverter output.
Input the RDY signal of the FR-HC2 (the RYB signal of the FR-XC, the RDYB signal of FR-CV, or the RDA signal of
FR-CC2).
(b) FR-HC2/FR-CC2 connection, instantaneous power failure detection (X11) signal: FR-HC2 connection, 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 FR-HC2/FR-CC2 connection, instantaneous power failure detection signal.
• For the terminal used for the X10 or X11 signal, set "10" (X10) or "11" (X11) in any of Pr.178 to Pr.189 and assign the
function. (For the separated converter type, the X10 signal is assigned to terminal MRS in the initial setting.)
NOTE
• For details of the high-duty brake resistor (FR-ABR), brake unit, high power factor converter (FR-HC2), multifunction
regeneration converter (FR-XC), or power regeneration common converter (FR-CV) connections, refer to
details on each option, refer to the Instruction Manual of each option.
• Setting Pr.30 = "2" will reset the inverter, and "Err" is displayed on the operation panel during the reset.
 Logic reversing of the Inverter run enable signal (X10 signal, Pr.599)
• Use Pr.599 X10 terminal input selection to select the X10 signal input 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 run
enable signal sent from the option unit.
