Activate automatic DC−injection braking (auto DCB)
1. Select the hold time >0.00 s under C0106:
– The automatic DC−injection braking (auto DCB) is active for the set time.
– Afterwards, the controller sets pulse inhibit (keypad display: ).
2. Select the condition for activating the automatic DC−injection braking under C0196:
– C0196=0: auto DCB active if the output frequency is lower than the operating threshold
(C0050<C0019)
– C0196=1: auto DCB is active if the output frequency is lower than the operating threshold
(C0050<C0019) and the setpoint is lower than the operating threshold (setpoint<C0019)
3. Set the operating threshold under C0019.
) Note!
If DC−injection braking is operated too long with high brake current or brake voltage,
the connected motor can be overheated!
Setting tips
Use C0019 to set a dead band in the setpoint. If DC−injection braking is not to be active here,
set C0106 = 0.00 s.
C0019 can be referred to a process variable.
7.5.5 AC motor braking
) Note!
This function cannot be used with a 8200 motec!
