Command, function and parameter description
Section 6-3
Description:
The SCOPE_POS parameter contains the current Table position at which the
SCOPE command is currently storing its first parameter.
Note This parameter is read-only.

6-3-172 SELECT
Type:
Program Command
Syntax:
SELECT
“program_name“
Description:
The SELECT command specifies the current program for editing, running, list-
ing, etc. SELECT makes a new program if the name entered does not exist.
The program name can also be specified without quotes.
When a program is selected, the commands COMPILE, DEL, EDIT, LIST,
NEW, RUN, STEPLINE, STOP and TROFF will apply to the currently selected
program unless a program is specified in the command line. When another
program is selected, the previously selected program will be compiled. The
selected program cannot be changed when a program is running.
Precautions:
This command is implemented for an offline (VT100) terminal. Motion Perfect
automatically selects programs when you click on their entry in the list in the
control panel.

6-3-173 SERVO
Type:
Axis Parameter
Description:
The SERVO parameter determines whether the base axis runs under servo
control (SERVO=ON) or open loop (SERVO=OFF). In closed loop, the motion
control algorithm will output a speed reference signal determined by the con-
trol gain settings and the following error. The position of the Servomotor is
determined using the motion control commands.
In open loop, the speed reference signal is completely determined by the
S_REF axis parameter.

AXIS, FE_LIMIT, S_REF, S_REF_OUT, WDOG
Example:
SERVO AXIS(0) = ON
’Axis 0 is under servo control
SERVO AXIS(1) = OFF
’Axis 1 is run open loop
6-3-174 SERVO_PERIOD
Type:
System Parameter
Description:
The SERVO_PERIOD parameter sets the servo cycle period of the MC Unit.
The timing of the execution of the program tasks and the refreshing of the
control data and I/O of the Unit are all depending on this setting. The parame-
ter is defined in microseconds. The MC Unit can be set in either 0.5 ms or
1.0 ms servo cycle.
!Caution
When the parameter has been set, a power down or software reset (using
DRV_RESET) must be performed for the complete system. Not doing so may
result in undefined behaviour.
