<1> Remove the jumper when installing a DC link choke. Models 5A0041 to 5A0242 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. Leaving L8-55 enabled may cause a braking resistor fault (rF). Additionally, disable Stall
Prevention (L3-04 = 0) when using an optional regenerative converter, regenerative or braking units, or dynamic braking option.
Leaving If L3-04 enabled may prevent the drive from stopping within the specified deceleration time.
<3> Supplying power to the control circuit separately from the main circuit requires 24 V power supply (option).
