Drive is expecting a Jog Edge and is receiving a continuous signal

Open all jog buttons and remove all jog commands

10

A conflict exists between the Encoder PPR programming (Par 232 or 242) and the
encoder configuration for edge counts (Par 233, bits 4 & 5)

Verify encoder data and reprogram

11
