selected reference source. The drive will ramp to the reference level
provided by the HIM at the rate specified in Accel Time 1 (140), Accel
Time 2 (141), Decel Time 1 (142) and Decel Time 2 (143). Be aware that
an abrupt speed change may occur depending upon the new reference
level and the rate specified in these parameters. Failure to observe this
precaution could result in bodily injury.
