Configuring the Position Outer Loop
The position outer control loop includes:
• Position gain profiler
• Position PI input
• Position PI output
• Type 3 position regulator
þ
To select the position outer loop:
▲
Set OCL SELECT (P.817) to POSITION .
Refer to figure A.16 in Appendix A of the software manual (D2-3444) as you configure
the position outer loop.
11.1 The Position Gain Profiler
The position gain profiler block uses equations that are based on the dynamic physical
properties of the connected load to maximize system response and stability.
Gain profiling should not be used when a type 3 position loop (no speed loop) is
selected (
OCL TYPE 3 POSN REG EN (P.814) is set to ENABLED ; see section 11.4).
The position gain profiler block has six inputs. SPEED CROSS OVER (P.133) is calculated
by the speed loop gain profiler block (see section 3.5). The remaining five inputs are
user-configurable.
Variable Diameter Applications
þ
To configure the gain profiler block inputs for variable diameter
applications:
▲
Set POS PROFILER ENABLE (P.253) to ENABLE .
