How to scale the PID actual (feedback) signal 0…10 bar / 4…20 mA
PID feedback is connected to AI1 and 4016 ACT1 INPUT is set to AI1.
1. Set 9902 APPLICATION MACRO to 6 (PID CONTROL). Check scaling: 1301
MINIMUM AI1 as default 20% and 1302 MAXIMUM AI1 as default 100%. Check
that 1106 REF2 SELECT is set to 19 (PID1OUT).
2. Set 3408 SIGNAL2 PARAM to 130 (PID1 FBK).
3. Set 3409 SIGNAL2 MIN to 0.
4. Set 3410 SIGNAL2 MAX to 10.
5. Set 3411 OUTPUT2 DSP FORM to 9 (DIRECT).
6. Set 3412 OUTPUT2 UNIT to 0 (NO UNIT).
7. Set 4006 UNITS to 0 (NO UNIT).
8. Set 4007 UNIT SCALE to 1.
9. Set 4008 0% VALUE to 0.
10.
Set 4009 100% VALUE to 10.
How to scale the PID setpoint signal
1. Set 4010 SET POINT SEL to 19 (INTERNAL).
2. Set 4011 INTERNAL SETPNT to 5.0 ("bar" is not displayed on the drive control
panel) as an example.
