Parameters
Parameter A055 and A058 define the duration of DC injection braking. The value is set within the
range from 0,1 to 60 seconds.
Parameter A056
defines wheter the DC brake is active depending on time or depending on a
contact.
Parameter A059 defines the carrier frequency during DC braking. With high carrier frequency the
maximum possible braking torque is reduced.
DC brake always active (A051=01):
If the DC brake is active (A051 = 01) this function is active at each Start and/or Stop.
After the Start-command the DC brake is active during the time set with parameter A058.
After the Stop-command the inverter runs down along the set deceleration ramp and starts with DC
braking at the frequency set with parameter A052.
