When using the high power factor converter (FR-HC)
1) Set "2" in Pr. 30.
2) Use any of Pr. 180 to Pr. 186 to assign the following signals to the contact input terminals.
#
X10: FR-HC connection (inverter operation enable signal) (Note 1)
To make protective coordination with the high power factor converter (FR-HC), shut off the inverter
output using the inverter operation enable signal. Enter the RDY signal of the high power factor
converter.
#
X11: FR-HC connection (instantaneous power failure detection signal)
When the computer link inboard option (FR-A5NR) is used and the setting is made to hold the pre-
instantaneous power failure mode, use this signal to hold that mode. Enter the instantaneous power
failure detection signal of the high power factor converter.
* Set "10" and "11" in any of Pr. 180 to Pr. 186 to allocate the terminals used to input the X10 and X11
signals.
Note: 1. The X10 signal may be replaced by the MRS signal.
2. When terminal assignment is changed using Pr. 180 to Pr. 186, the other functions may be
affected. Check the functions of the corresponding terminals before making setting.
