Hello, we are controlling the motor as VME(MVME6100) and OMS maxv controller. we found an error information on EPICS IOC suddenly who used well before. 
The motor moves, but it moves only a little when the client sends more commands. (ex. 10mm needs to be sent commands for 10mm movements more than 10 times to send)
This problem seems to be a problem that the controller does not recognize the pulse as the log message below repeats indefinitely.

error message -> "filename="../devOmsCom.cc" line number=324 Overriding invalid acceleration."

This error message repeats indefinitely.I still get an error even though I set the accl value to 2. It keeps happening even if I don't move the motor.

Do you happen to know the solution? I also checked if there are multiple pv's running through Cainfo.
