Unidrive SP Regen Installation Guide 143
Issue Number: 2 www.controltechniques.com
The motorised pot modes are given in the following table.
When this bit is set to 0 the motorised pot output is limited to positive values only (i.e. 0 to 100.0%). Setting it to 1 allows negative outputs
(i.e. ±100.0 %).
This parameter defines the time taken for the motorised pot function to ramp from 0 to 100.0%. Twice this time will be taken to adjust the output from
-100.0 % to +100.0 %.
This parameter can be used to restrict the output of the motorised pot to operate over a reduced range so that it can be used as a trim, for example.
