When the built-in brake resistor, the brake unit (BU, FR-BU) is used
Set "0 (initial value), 10 or 20" in Pr. 30. The Pr. 70 setting is made invalid.
At this time, the regenerative brake duty is as follows. (The built-in brake resistor is provided for
the 00250 or less.)
●
FR-A 740-00023 to 00250 .........2 %
●
Other than the above .................0 % (without built-in brake resistor)
When using the high-duty brake resistor (FR-ABR) (00620 or less)
Set "1, 11 or 21" in Pr. 30. Set Pr. 70 as follows.
●
00250 or less .............................10 %
●
00310 or more ...........................6 %
When using a brake unit (MT-BU5) and power regeneration converter (MT-RC)
Set "1, 11 or 21" 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 regenerationcom-
mon 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 RS-485 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) in any of Pr.178 to Pr. 189.
