In a master slave configuration of Simoreg DC Master 6RA70 DC Drive, the master drive is tripping at F048 with a fault value 2
F048 = Fault in measuring channel for digital speed sensing using pulse encoder
fault value 2 = Pulse encoder defective:
I have checked the following parameters but not able to solve the problem.
· EMC-related interference on a pulse encoder signal (terminals 28 to 31)
· Pulse encoder defective
· Interruption in an encoder cable
· Short circuit between an encoder cable and the supply voltage or another encoder cable
· P110 or P111 is incorrectly set (resulting in incorrectly calculation of EMF)
Encoder is also working.
Please suggest a suitable solution.
