5.3.4 Connection Information
F1 Line protection in accordance with VDE 0100, slow-blowing fuse of 2-3 times
the transformer's rated current or motor protection switch in systems with only
one axis.
Current-operated e.l.c.b.
The principles on which the power converter and the motor work lead to rela-
tively high leakage currents to earth, i.e. the drive may be incompatible with
current-operated e.l.c.b. systems. For configuration, take into account provisional
standard EN 50178:1994 Section 5.2.11.
T1 Autotransformer YNO or isolating transformer Yny0; inrush current limitation
device depending on the type and power of the transformer. For further details,
refer to Transformer Accessories
T2 Isolating transformer for additional feed of the auxiliary controller supply
BUG 2 and 3: isolating transformer 230/230, 160 VA, No. 1900 7153
BUG 20: isolating transformer 230/230, 250 VA, No. 1900 7176
With this option, error messages are retained even if K1 has dropped. The op-
tion is not necessary for operation. Use one transformer per basic unit.
K1 Mains contactor with auxiliary contact for controller enable
K2, R2 Starting current limitation prevents the B6 rectifier's permissible non-repetitive
peak current, I

Intermediate circuit connection to the BUS units via the supplied busbars.
With several servo units, arrange the BUG in the middle.
Wire the BUG 3 with 4 mm² wires.
DANGER
When using autotransformers, the intermediate circuit carries mains potential;
When using isolating transformers, ground L- (ZK-).

Drives that have a very high centrifugal mass or acceleration/braking drives are
run with external ballast. For more information, refer to the section entitled BUR
Resistor Unit.
