DC Bus Capacitor Unit HLC01.1

7.1

Application Instructions

DOK-INDRV*-ADDCOMP****-PR02-EN-P
Possible damage to the drive controller!
In operating cycles of more than 30 cycles per minute the
DC bus capacitors within the drive controller can be
overloaded when the mains supply voltage decreases.
CAUTION
Use DC bus capacitor units.
Using a DC bus capacitor unit you can increase the storable DC bus
energy. This makes sense
• for applications with short cycle times (> 30 cycles per minute). The
continuous power of braking resistor will be reduced and with it the lost
heat
• for applications, which need also in case of mains supply failure a
certain amount of energy (e.g. for return motions)
• to back the DC bus for drive systems with DC bus connections > 2 m
between the drive controllers
