Related Functions: FU2-33 [Rated Current of Motor] FU2-33: the DC current is limited by this parameter.

Note: The DC injection braking function does not function when either FU1-12 or FU1-13 is set to “0”.

Note: FU1-12 [Starting DC Injection Braking Voltage] is also used as the DC Injection Braking Voltage for the multifunction input when the multifunction input is set to “DC braking”.
