• P3-06, Speed Proportional Position Trim Lower Limit, Examples. For the following, assume E1-04 is set to 60 Hz and
P3-06 is set to 10.00%:
With Speed Proportional Position Trim disabled, a PI output of 10% adds 60 Hz * 10% = 6 Hz, regardless of the value
of follower reference after gear ratio.
With Speed Proportional Position Trim enabled, and follower reference after gear ratio of 30 Hz, a PI output of 10%
adds 60 Hz * 10% * (30 Hz / 60 Hz) = 3 Hz.
With Speed Proportional Position Trim enabled, for any follower reference below the P3-06 value multiplied by E1-04
(10% * 60 Hz = 6 Hz), the trim amount is limited to P3-06.
In this case, a PI output of 10% adds 60 Hz * 10% * 10% = 0.6 Hz.
