4.0 Conditions that would merit re-tuning the drive
Hardware additions made to the drive, such as an output reactor or a
dv/dt filter.
Physical changes to the process, such as the motor being changed
(even if the it is an identical motor, bearing changes and coupling
changes can have an influence on performance), gearbox changes,
length of motor cables changed.
Process changes, such as motor loading, and speed range changes to
name a few. Note that since the type of change described is wide-
ranging manual tuning may be a better alternative. Review the
parameters effected for P115=5.
Software changes, P068, P095, P097, P100(this includes any changes
in P101 through P109), P339, P340, P357.
Exceptions:
• If the carrier frequency of P340 is adjusted in multiples that re-
tuning is not required (ie: 2.5 kHz to 5.0 kHz)
• If P100 is changed from a value of 4 to 5.
Repair or Maintenance, such as replacing either the motor or the CUVC
logic card.
Exceptions:
• If tuning parameters P103, P116, P120, P223, P235, P236,
P240 and P471 had been recorded prior to the CUVC card
being replaced.
