1. Features
The brake choppers 6032, 6033 und 6034 are additional
components for frequency inverters with DC bus.
In generator mode, e.g. during deceleration of the drive, the
machine feeds back energy into the DC bus of the controller. If, as
a result, the DC bus voltage exceeds the maximum permissible
value, pulse inhibit will be set and "Overvoltage" will be displayed.
As soon as the voltage falls below this maximum permissible value,
the controller will be enabled again.
•
Enclosure IP00 for cabinet assembly
•
Assembly on DIN rails, alternatively assembly on module
resistors
•
Dissipation of brake energy in form of heat
•
Very short brake times possible
•
If not defined, the controller will not set pulse inhibit during
braking
