Encoder 1 speed filtered value is not showing in ACS880
Hi,
Q1. I wanted to measure speed of motor by an incremental encoder(HTL with 1024 ppr) connected to motor shaft directly through FEN-31 in a crane application. I configured parameter group (90, 91, 92) according to given procedure in ACS880 Crane application manual. There is no fault in drive. Status LED of FEN-31 is healthy. But There are no value in Encoder 1 speed (Par-90.10), Encoder 1 speed filtered (Par-01.04). Please help me informing how to configure Encoder to get speed feedback and use it to over speed protection. First time I am working with encoder and ACS880.
Q2. When I provide start command to start forward, motor starts in reverse for a moment with a jerk and then starts in forward direction. In reverse direction also same thing happens. This is severe when drive is operated remotely with DI than locally. Normal ID run done successfully. Speed proportional gain (Par-25.02) & Speed Integration time (Par-25.03) have been adjusted but problem still persists. Please assist me to solve.

Hi
to give you a answer to the both question, could you post the parameter file of your drive?
I don't have the crane application FW, but if it's an analysis of how the encoder was set up, maybe I can help you.

For Q1
First, please check your setting is
Par 90.41=Encoder 1
Par 91.10 = FEN-31
Par 91.2= FEN-31
Par 91.11=FEN-31
par 7.52=FEN-31
Par 92.1=HTL
Then, See Par 1.4 for Encoder 1 speed filtered
Hope this help
