PLEASE quick help about brushless motors

[Heino Geerdens]

Hi all,

Its about 5am here I'm called for a intervention on a CNC bender. The problem I think are 2 brushless Servo motors that are broken
Type
Siemens
1FK6042-6AF71-1EH0
2.8A - 6200/min 228V

I don't have that specific type as a spare part, I do have one with similar specifications
Type
Siemens
1FK6042-6AF71-1EG0
2.8A - 6200/min 228V

Can anyone tell me if it would be safe to change them???

Thx

I searched Google with the last 4 digits dropped. Go to this page and check the specs.

The Configurator shows this difference:
G PLAIN SHAFT, TOLERANCE N W/O HOLDING BRAKE;
H PLAIN SHAFT, TOLERANCE N WITH HOLDING BRAKE;

That's the best I can do.
