position definitions during the product life
exceeds the maximum allowed (applies
only to systems with absolute feedback).
This is an unrecoverable fault, the drive
must be sent back to the factory.
E02
Velocity Exceeds Position Rollover /2
The velocity command or feedback exceeds
half the machine cycle length per
millisecond (applies only when the
machine cycle position rollover is enabled).
Increase machine cycle size or reduce
velocity profile. This error only applies to
firmware versions prior to 1.10.
