Installing and Operating the SP200 AC Drive
Step 2. Set P-29 (Process Operation) = 2 to select PI control as the process
operation.
Step 3. Set P-20 (Main Speed Reference) = 4 to select P-29 (Process Operation)
as the main speed reference.
Step 4. Set P-26 (Process Proportional Gain) and P-27 (Process Integral Gain) to
nonzero values that are chosen to match the dynamics of the process being
controlled and also the desired response.
