11.4.3 Migraon of Lenze Inverter Drives 8200/8400
The behaviour of the Lenze Inverter Drives 8200/8400 in case of automac DC braking is dif-
ferent: In case of these inverters, aer the auto DCB hold me has elapsed, the motor is dee-
nergised (by means of pulse inhibit) unl the setpoint exceeds the auto DCB operang thresh-
old. In order to make a migraon to the i500 inverter series easier, the seng 0x2B84:006
(P704.06) = "1" serves to acvate the same behaviour in the i500.
The following example illustrates the behaviour of the funcon if 0x2B84:006 (P704.06) = "1".

①
If the setpoint falls below the operang threshold set in 0x2B84:003 (P704.03), the DC braking gets acve for the hold me set in
0x2B84:002 (P704.02).
②
Aer the hold me has elapsed, the power secon is switched o.
③
If the setpoint exceeds the operang threshold again, the power secon is switched on again. The motor is accelerated to the setpoint
again.
