2.4 Connection of stand-alone option unit
The inverter accepts a variety of stand-alone option units as required.
Incorrect connection will cause inverter damage or accident. Connect and operate the option unit carefully in accordance with
the corresponding option unit manual.
2.4.1 Connection of a dedicated external brake resistor (MRS type, MYS type, FR-ABR)
(0.4K(SC) or more)
Install a dedicated brake resistor (MRS type, MYS type, FR-ABR) outside when the motor is made to run by the load, quick
deceleration is required, etc. Connect a dedicated brake resistor (MRS type, MYS type, FR-ABR) to terminal P/+ and PR.
(For the locations of terminal P/+ and PR, refer to the terminal block layout
(page 16) .)
Set parameters below.
∗1
Do not remove a jumper across terminal P/+ and P1 except when connecting a DC reactor. (Not available for single-phase 100V power input model.)
∗2
The shape of jumper differs according to capacities.
