3. P gain of speed controller
The total P gain results from the following parameters.
SCG
(_SCON)
Parameter for P gain of speed controller
SCGFA
(_SCON)
For scaling and fine adjustment of SCG (0 - 999%,
factory setting 100%)
SCJ
(_SCON)
Moment of inertia of installation
MOJNM
(_MOT)
Moment of inertia of motor. This is set to suit the motor
by loading the motor specification from the S
MART
C
ARD
SCG is factory set on the assumption that the moment of inertia of the installation = 0. The
moment of inertia of the installation should be set using the parameter SCJ.
This results in proportional matching of the resulting controller gain. Using parameter SCGFA
it is possible to fine tune the gain on-line. The gain of the controller is calculated as follows:
SCG SCJ MOJNM
MOJNM
SCGFA

.
If the moment of inertia of the installation is not known, the function of the Servocontroller
should be used for setting speed control, as described in
Section 8.3.1.
Permissible maximum values for SCG, SCGFA and SCJ are each calculated such that the
total controller gain is in the permitted area of 0 - 10
8
.
4. Reset time of speed controller SCTLG (_SCON)
The lag time should be calculated in advance for the basic setting of the Servocontroller and
does not normally need to be changed again.
