MANUAL TUNING
function block
The controllers of the DCS 500B drive can be tuned manually or
automatically. There is an automatic tunig function for the armature
and field current controller. The speed loop, the armature current,
the EMF and field current controller can be manually tuned. Both
tuning methods are initalized by a parameter.
Selection of the tuning The manual tuning can be done if LOCAL-mode is selected with the
panel or by external digital I/O.
The selection is made by means of parameter:
DRIVEMODE (1201)
4 = armature current controller
7 = first field exciter
8 = second field exciter
9 = speed loop (reference chain and speed controller)
10 = EMF controller
Selection replaces normal references to the controllers or the speed
loop with the manual tuning reference. E.g. in a case of the speed
loop the LOCAL SPEED REF is replaced with manual tuning refe-
rence.
Source of the manual tuning reference can be selected from four
different sources:
POT1 VALUE (1204) range: -32 768...32 767
POT2 VALUE (1205) range: -32 768...32 767
SQUAREWAVE (11206)
generator whose levels are set with POT1 and POT2 VALUE
and time interval with PERIOD btw.POT1/2 (1206)
TEST REF (11207) range: 0...65 535
The selection is made by the signal TEST REF SEL (11209).
0 = [ZERO] reference is zero
1 = [POT1] POT1 VALUE (1204)
2 = [POT2] POT2 VALUE (1205)
3 = [SQRW] SQUAREWAVE (11206)
4 = [TEST] TEST REF (11207)
During the manual tuning measurements can be made e.g. with
CMT/DCS500 tool or analog outputs.
