1 Brief description
BA8230 1
1.1 General 8230 frequency inverter are processor-controlled pulse inverters with a field-orientated
control concept for continuous low-loss speed adjustment of AC motors.
The power stack consists of a diode rectifier in a 3-phase bridge circuit on the mains
side and an IGBT inverter on the motor side.
The basic inverter models are designed for standard applications. Through suitable
options (eg. bus couplers, encoder interface) the units can be integrated into
automation systems and can also fulfil highly dynamic requirements.
Operation of all units is identical throughout the entire type range. Easy familiarisation
and operation as well as maximum flexibility were the prime objectives during
development.
The inverters are operated and parameters adjusted by means of a control unit
(BDE).
Connection to automation systems is possible through conventional bus systems (see
field bus coupler options).
With a mains voltage range from 380 to 480 V build-in units cover the power range
from 144 kVA to 330 kVA.
In conjunction with standard asynchronous motors the drive capacities provided are
therefore as follows:
- At unit rated current
110 kW to 200 kW, 400 V
- At unit 1.5 x rated current
132 kW to 250 kW, 400 V
Note:
This operating manual applies to the following units:
8230 frequency inverter
Software version:
V2.0
Important!
8230 frequency inverter are designed as standard for operating on earthed networks.
