Servo drive errors A04 & A07

[ktipteh]

I am working with servo drivers and  my Unitronics servo drivers are showing errors A04 and A07. I know that I might have an issue with unstable voltage supply, but however other servo drivers near it don't show these errors, only my Unitronics servo drivers get these errors at the same time. 

What could be the issue? Which parameter should I fix to avoid these errors?

A07 - error must be corrected via parameters (or vrong encoder type selected).

A04 - overload - this is a problem of incorrect connection of the motor or encoder wires or overloading of the motor during the start-up process. Incorrect parameters for the motor encoder are also possible.

Unfortunately, you did not specify the markings of the servo components ( drive and motor) and it is impossible to add something more specific
