Figure 2.114 Simple Closed Loop Speed Control Block Diagram
Enable Simple Closed Loop V/f Mode
1. Connect the encoder output pulse wiring to terminal RP.
2. Set
A1-02 = 0 [Control Method Selection = V/f Control] .
3. Set H6-01 = 3 .
4. Set H6-02 [Terminal RP Frequency Scaling] to the speed feedback (pulse train input signal) frequency at the time
when the frequency reference is 100%.
Make sure that
H6-04 [Terminal RP Function Bias] = 0% and H6-03 [Terminal RP Function Gain] = 100%.
5. Select the detection method for the direction of motor rotation.
When you use an MFDI, set H1-xx = 7E .
6. Set C5 parameters related to ASR gain and integral time to adjust responsiveness.
Note:
•
Set A1-02 = 0 and H6-01 = 3 to show C5 parameters .
•
You cannot use Closed Loop V/f Control mode with the Motor Switch function.
