1-1Types and MeaningsofGain

The word“gain”appearsfrequentlyinthistechnicalguide.The gainisone of the indis-

pensable parametersof the ServoSystem. If the gain adjustmentof the ServoSystemis

insufficient, the operation of the ServoSystemwill be unsatisfactory,inwhichcasethe

ServoSystemwill causemachinery vibration and an alarm will result. Asummaryof the

ServoSystemand all gainsused forthe ServoSystemloopsare described below.

1-1-1SummaryofServoSystem

The ServoSystemusesfeedback loops. In a feedback loop, the responsevalue isfed back afterthe

command sothat the difference between the response and command valueswill be as close aspos-

sibletozero.The ServoSystemconsistsof three feedback loops(i.e., position loop,speed loop,and

currentloop).Refertothe following block diagram.

Position Loop

·The position loop isused tolet the rotation angle of the motor reachthe desired position (i.e., the de-

sired rotation angle)thatwasexternallydesignated.

·The speed command isoutput fromthe position loop tothe speed loop.

·The position loop feedsback the position data(i.e., the information on rotation angle)of the encoderor

resolver.

Speed Loop

·The speed loop isused tolet the motor rotate at the speed designated bythe externalanalog speed

command orthe speed command thatisoutput fromthe position loop.

·The currentcommand isoutput fromthe speed loop tothe currentloop.

·The speed loop feedsback the speed data of the encoderor resolver.

CurrentLoop

·The currentloop providesthe motorwiththe currentdesignated bythe currentcommand thatisoutput

fromthe speed loop.

·The currentloop feedsback the motorcurrentvalue.

The gainisa parameterto adjust the responsespeed ofafeedback loop.

1-1-2Gain

The gainisanotherwordfor magnification.

The difference between the command and responsevaluesin a feedback loop ismultiplied bythe gain

and the resultisoutput fromthe feedback loop.The difference between the targetposition and present

position inthe position loop, forexample,isobtained asa position deviation ordeviation countervalue.

The value multiplied bythe position loop proportionalgainisoutputasaspeed command.

Inthe actualServoSystem, the targetposition isexpressed by command pulsesand the presentposi-

tion isexpressed byfeedback pulses,bothfromwhichthe position deviation pertime unitis calculated.

The deviation countertotalsall the per-time-unitposition deviationsto obtainthe position deviation of

the ServoSystem.

The higherthe gain ofanyfeedback loop is, the higherthe outputof the feedback loop is. In otherwords,

if the gainincreases, the outputpowertofixthe deviation will increase.The ServoSystemwith high

gainsisidealbecausethe gainsensure a high responsespeed and reduce errors. If the gainsaretoo

high,however, the ServoSystemwill causemachine vibration according tothe size and rigidityof the

machine system.The ServoSystem, therefore,requiresgain adjustmentaccording tothe machine sys-

tem.

NoteRigidityindicatesthe engagementstrength of the machine system.The backlash orspring por-

tion ofamachine system reducesthe rigidityof the machine system.
