Hello, first time poster.
I am fairly capable of program a plc but I have trouble to get a servo drive working correctly.
I use an Allen Bradley Kinetix 3 with a Micrologic 1500. The signal is PTO.
The drive runs somewhat, but only in low frequencies (200-300Hz) and very stuttery. If I crank up the Hz, the drive won't turn anymore. It accelerates, stops and starts moving again for deceleration.
The drive is capable of up to 3MHz. The PLC has an output up to 20000Hz what gives a ratio of 1:150 master to follower.

Has anyone a tip where to look?
