<1> Remove the jumper when installing a DC link choke. Models CIMR-L 2A0085 through 2A0415 and 4A0045 through 4A0260 come with a
built-in DC link choke.
<2> Set L8-55 to 0 to disable the protection function of the built-in braking transistor of the drive when using an optional regenerative converter
or dynamic braking option.
<3> Set up a thermal relay sequence to disconnect drive main power in the event of an overheat condition on the dynamic braking option.
<4> Self-cooling motors do not require the same wiring necessary for motors with separate cooling fans.
<5> Supplying power to the control circuit separately from the main circuit requires a 24 V power supply (option).
<6> For control modes that do not use a motor speed feedback signal, PG option card wiring is not necessary.
