connection Operation without V
DC link
connection:
• Only approved for PWM frequency 4 kHz or 8 kHz.
The increased power requirement causes an additional load on the inverter. Take
this aspect into account during project planning of the drive. Failure to comply with
this aspect may cause the inverter to shut down due to overload.

NOTES
Operation with V
DClink
connection
(Connection of inverter terminal 8 to HF...-503 terminal V5 or HF...-403 terminal 7):
• Only approved for PWM frequency 12 kHz or 16 kHz. Take into account that in-
creased losses (= power reduction) occur in the inverter when operating the inverter
with 12 or 16 kHz.
• Optimized grounded filter effect.
• Higher filter effect in the low-frequency range (
≤
150 kHz).
• Set PMW fix = ON; the inverter must not be able to reduce the PWM frequency
automatically
• Strictly observe the following for HF...-403: V
DC link
connection only permitted if
V
mains
≤
AC 400 V, not with V
mains
= AC 500 V.
• The V
DClink
connection increases the inverter load. The DC link connection increas-
es the required inverter output current in relation to the rated output current of the
inverter as shown in the following table.
