6.2 Information on operation
Please observe the following for controller operation:
Stop!
l
Cyclic connection and disconnection of the supply voltage at L1, L2, L3 or +U
DC
,-U
G
mgiht
overload the internal input current limit:
– Allow at least 3 minutes between disconnection and reconnection.
l
During mains switching (L1,L2,L3) it is not important whether further controllers are supplied
via the DC bus.
6.2.1 Switching on the motor side
l
Switching on the motor side of the inverter is permissible for emergency switch-off.
l
Please note:
– Switching while a controller is enabled may cause the fault indication ”0Cx”
(short-circuit/earth fault in operating case x).
– For long motor cables and operation of controllers with smaller output power, leakage
currents through interfering cable capacitances may cause the fault indication ”OCx”.
– Switching equipment on the motor side must be dimensioned for DC voltages
(V
DC
max = 800 V).
