Connection Of Stand-Alone Option Unit; Connection Of A Dedicated External Brake Resistor (Mrs Type, Mys Type, Fr-Abr) (0.4K Or Higher) - Mitsubishi Electric FR-E700EX Instruction Manual

2.4

Connection of stand-alone option unit

The drive unit accepts a variety of stand-alone option units as required.
Incorrect connection will cause drive unit 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 or higher)
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 to terminal P/+ and PR.
(For the locations of terminal P/+ and PR, refer to the terminal block layout (page 15).)
Set parameters below.
