3.6.3.1 Undervoltage error (E.UP)
In Pn.00 "automatic restart E.UP", the automatic restart for the undervoltage error is activated in the factory
setting.
A typical application for the automatic restart E.UP (Pn.00) is operation on a bad power grid where sporadic
voltage dips are to be expected. With this function, the application continues running as soon as the mains
voltage is sufficiently high again.
3.6.3.2 Overvoltage error (E.OP)
The error overvoltage usually occurs at deceleration in connection with an overcurrent error.
At automatic restart the blocking time modulation is at least 1 second.
3.6.3.3 Overcurrent error (E.OC)
The automatic restart after occurence of an overcurrent error is activated with Pn.02 "automatic restart E.OC".
It can be used at burst-like overloads.
The blocking time modulation will proceed as in overvoltage errors.
After 10 restart attempts, the inverter state must be unequal to the blocking time modulation or the overcurrent
error for at least one second, otherwise the restart is aborted.
3.6.3.4 Malfunction messages and pre-warnings
A malfunction response with automatic restart is selected in parameters Pn.03, Pn.05, Pn.08, Pn.09, Pn.10,
Pn.11, Pn.16, Pn.18 with the value 3 .
3.6.4 Special functions
In these parameters, many different functions for adapting the inverter behaviour to special applications are
pooled.
Pn.19: Operating mode
Value
Description
0: Master with commutation choke
For high power regenerative units can be parallel connected.
One device must be set to "master", the other set to "slave" (pn.19).
Single units are always master.
The coupling of the regenerative units is made by terminals
X2A.16/18, since this is a fast digital input.
1: Master with harmonic filter
2: Slave with commutation choke
3: Slave with harmonic filter
4: Selection of Master/Slave with
commutation choke via input I1, I2
or I3
Input selection for 4 and 5 in the parameters I1:di11/I2:di12/I3:-
di13 each Bit 1 or pn.31
5: Selection of Master/Slave with
harmonic filter via input I1, I2 or I3
The input query at 4 or 5 will once held by Power-on reset.
