Hello Sir,

Can you please help me to solve the encoder fault F31117 in CU250S2-PN, G120 drive. I am using Simotics M-1PH1 motor which has TTL encoder. Wiring is correct as per color code. I have connected encoder to D-Sub interface. Please suggest to rectify this problem.

Thanks,

Ram.

Hello,

which SMC and Encoder cable do you use?

Split from Fault no. F31117 even though encoder connection seems correct.

Can you please provide complete article number of PH motor connected & encoder connection wiring diagram details connected to CU250S2-PN CU?

Are you 100% sure the encoder signal is A & A- (like +5 & -5V), B & B-, and Z & Z-?

Have you put an oscilloscope on the encoder signal wires to verify they are both above and below 0V reference for each channel and that A & B channels are able to indicate direction, and that the Z channel fires only once per revolution?
