Parameter
When the brake unit (BU, FR-BU) is used
Set "0" (initial value), "10, 20, 100" or "120" in Pr. 30. The Pr. 70 setting is made invalid.
When using a brake unit (MT-BU5) and power regeneration converter (MT-RC)
(01800 or more)
Set "1, 11, 21, 101" or "121" in Pr. 30.
Set "10%" in Pr. 70 when using a brake unit (MT-BU5).
Set "0%" in Pr. 70 when using a power regeneration converter (MT-RC).
When using the high power factor converter (FR-HC, MT-HC) or power regeneration
common converter (FR-CV)
Set "2" in Pr. 30. The Pr. 70 setting is made invalid.
Use any of Pr. 178 to Pr. 189 "Input terminal function assignment" to assign the following signals
to the contact input terminals.
● X10 signal: FR-HC, MT-HC connection, FR-CV connection (inverter operation enable signal)
To make protective coordination with the FR-HC, MT-HC or FR-CV, use the inverter operation
enable signal to shut off the inverter output. Input the RDY signal of the FR-HC, MT-HC
(RDYB signal of the FR-CV).
● X11 signal: FR-HC, MT-HC connection (instantaneous power failure detection signal)
When the setting has been made to hold the mode at occurrence of an instantaneous power
failure for RS485 communication operation, use this signal to hold the mode. Input the Y1
or Y2 signal (instantaneous power failure detection signal) of the FR-HC, MT-HC.
For the terminal used for X10 or X11 signal input, assign its function by setting "10" (X10) or "11"
(X11) to any of Pr. 178 to Pr. 189.
NOTES The MRS signal can also be used instead of the X10 signal.
Refer to section 3.7 for the connection of the brake unit, high power factor converter
(FR-HC, MT-HC) and power regeneration common converter (FR-CV)
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection)
may affect the other functions. Please make setting after confirming the function of each ter-
minal.
When Pr. 30 = "2", "Err" is displayed on the operation panel as the inverter is reset by the
setting.
