1.4.15 High power factor converter connection (X10, X11)
(common)
Used with the inverter in accordance with the Japanese
harmonic suppression guidelines issued by the Agency for
Natural Resources and Energy of Japanese Ministry of
Economy, Trade and Industry (formerly Ministry of
International Trade and Industry), the high power factor
converter (FR-HC, MT-HC) is an optional high power factor
converter unit designed to suppress harmonics to the input
power supply.
When connecting the high power factor converter, perform
wiring securely as shown in figure (1) and (2). Incorrect
connection will damage the high power factor converter
and inverter.
After making sure that the wiring is correct, set [
Pr.30
Regenerative function selection = 2] for , or set
[ Pr.30 Regenerative function selection =0 or 2] in
. (Refer to page 340)
Having a power regeneration function, the high power
factor converter returns power in the regeneration mode.
For the 7.5K or less, the brake circuit built-in the
inverter is not activated.
Undervoltage and instantaneous power failure are
detected by the high power factor converter. When the
protective function of the high power factor converter is
activated, the inverter operation enable signal shuts off the
inverter output. The undervoltage and instantaneous power
failure protective functions of the inverter itself are invalid.
When you need automatic restart after instantaneous
power failure, choose automatic restart after instantaneous
power failure in the inverter and also set the parameter to
activate automatic restart after instantaneous power failure
in the high power factor converter. The inverter restarts in
accordance with the automatic restart after instantaneous
(1) Connection with the FR-HC (55K or less)
*1 Always keep terminals R/L1, S/L2, T/L3 open. Incorrect
connection will damage the inverter. (In ,
E.OPT (Option fault) will occur. (Refer to page 97))
*2 Do not insert an MCCB between terminals P/+ and N/-
(between P and P/+, between N and N/-). Opposite
polarity of terminals N/-, P/+ will damage the inverter.
*3 Use [ Pr. 178 to Pr. 189 Input terminal function selection ] to
assign terminals used for X10 and X11 signal.
For , X11 signal is unavailable. (Refer to
page 37)
Terminal MRS can be used when not using inverter
operation enable signal (X10).
For communication where the start command is sent only
once, for example RS-485 communication operation, use
the X11 signal when making setting to hold the mode at
occurrence of an instantaneous power failure. (Refer to
page 331)
*4 For , remove jumpers between terminal R/
L1 and R/L11 as well as between S/L2 and S1/S21, and
connect the power supply for the control circuit to
terminals R1/L11 and S1/L21.
For , connection is unnecessary because
do not have terminal R1/L11 and S1/L21.
*5 The voltage phases of terminals R, S, T and terminals
R4, S4, T4 must be matched.
*6 Use sink logic (factory setting) when the FR-HC is
connected. The FR-HC cannot be connected when
source logic is selected.
