Good afternoon! I have two irc5 robots(IRB360) with the pick master 3 add-on, and during my work shift, I get the error 50174 “WObj not connected…” 2-4 times. Can you tell me what the problem might be?
Hi，try modify Max External Pos Adjustment ,Start ramp, Stop ramp
That error means the conveyor-tracked WObj lost its connection during execution. Happens intermittently so it is almost always one of these:
Encoder dropout — check shielding on the encoder cable first. Delta robot drives generate a lot of electrical noise and even a brief signal glitch kills tracking sync.
Object past the pick window — PickMaster queued the pick, but by execution time the object moved out of the reachable zone. WObj goes invalid mid-motion.
Real tip: pull the full event log and look at what happens a few seconds before each 50174. There is almost always a preceding fault that gives the actual root cause.
Also worth checking: Max pos error in the PickMaster 3 conveyor config, not just the ramps. If that threshold is too tight it will disconnect the WObj on any minor conveyor speed variation.
