5. FUNCTION AND DATA SETTINGS

Example 1: Step Input

10%

Step Signal

Flow rate value

after rate limiting

Flow rate value after

damping

➂

➀

➁

➃

63.2%

Input: 0 to 10%

Damping time constant: 3 sec.

Dead time: 3 sec.

Rate limit value: 1%

Dead time: 3 sec. (Sampling 80 ms × 18 times)

Shows 1% response cause of excessive signal beyond the rate limit. However, actual

output is under damping that described by a solid line.

Shows the flow rate signal (1%) of just after damping calculation ( 1 ) and rate limit

value.

This signal is recognized as a flow rate signal since it does not return to within the

rate limit value within the dead time.

The output signal follows the damping curve and tracks the step signal.

Example 2: Slurry Noise

Slurry Noise

Flow rate value after rate limiting and damping.

Flow rate value after

rate limiting

Dead time: 1 sec.

+1%

–1%

Input: 0 to 10%

Damping time constant: 1 sec.

Dead time : 1 sec.

Rate limit value: 1%

The left figure shows that the slurry

noise is not a flow rate signal.

The rate limit value can be set in parameter No. “n03”.

Setting Range: 0 to 10%

The dead time can be set in parameter No. “n04”.

Setting Range: 0 to 15 sec.
