Question:
Can 935x brake choppers be operated in a DC-bus connection with 9400 drive controllers?
Answer:
Yes, a combination 935x with the following devices is possible:
9400 Multi Drives:
all
Supply modules:
all
9400 SingelDrive:
E94ASxE0324 15 kW
E94ASxE0474 22 kW
E94ASxE0594 30 kW
E94ASxE0864 45 kW
E94ASxE1044 55 kW
The 935x brake modules are not allowed to be combined with the following SingleDrive devices.
9400 Single Drives:
E94ASxE0024 0.37 kW
E94ASxE0034 0.75 kW
E94ASxE0044 1.5 kW
E94ASxE0074 3.0 kW
E94ASxE0134 5.5 kW
E94ASxE0174 7.5 kW
E94ASxE0244 11 kW
E94ASxE1454 75 kW
E94ASxE1724 90 kW
E94ASxE2024 105 kW
E94ASxE2454 130 kW
E94ASxE2924 150 kW
E94ASxE3664 190 kW
E94ASxE4604 240 kW
E94ASxE5724 300 kW
E94ASxE6354 335 kW
E94ASxE6954 370 kW
E94BSxE1454 75 kW
E94BSxE1724 90 kW
E94BSxE2024 105 kW
E94BSxE2454 130 kW
E94BSxE2924 150 kW
E94BSxE3664 190 kW
E94BSxE4604 240 kW
Note:
If one of the mentioned 9400 Single Drives is integrated in the DC-bus connection, it is
not allowed to connect any 935x brake module to the CD-bus connection.
The mentioned devices contain current-compensated chokes in the DC-bus, which are able to trigger a 935x brake chopper to start a sympathetic oscillation, so that it can change over to a continuous chopper operation.
The following technical combinations are possible:
__________________________________________________________________________________
935x brake chopper | 9400 supplier _ | 9400 device size 1-3 and 8-10 | 9400 device size 6-7 X _ | __ X | ___ O | X ___
O __ | __X | ___X | X ___
- Several brake choppers of one type are allowed to be integrated in the DC-bus connection.
X = brake chopper in the DC-bus
O = no brake chopper in the DC-bus
For synchronisation please consider:
935x brake choppers with 9400 supplier are to be synchronised.
935x brake choppers with 9400 axes, device size 6-7 cannot be synchronised.
