7 DC Bus Capacitor Unit HLC01.1
DC Bus Capacitor Unit HLC01.1 7-1
CAUTION
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.
⇒ 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
