4 Quick-start guide
4.4.2 Configuration of the display unit
By adapting the display units, physical variables such as the position, speed and
acceleration can be displayed in the MetronixServoCommander
®
program as required by
your specific application. If you use a linear axis, for example, you can select translatory
display units so that the position will be indicated in mm, the speed in mm/s and the
acceleration in mm/s².
As the configuration of the display units is highly complex, only the basic principles will be
discussed in this section. You can find a detailed description in section 7.3 Display units
on page 126.
The field Display mode offers a range of default settings to choose from. The mode
Standard values covers a wide range of applications.
4.4.2.1 Rotatory operation
The following is possible for rotatory systems:
l Position values in revolutions, degree or radian
l Speed values in revolutions/s or degrees/s or rad/s
l Acceleration values in revolutions/s² or degrees/s² or rad/s²
In rotatory mode, you can enter a gear ratio if you want to adjust your application to the unit
at the output. To do so, tick the checkbox with gear.
4.4.2.2 Translatory operation
The following is possible for translatory systems:
l Position values in units of length: m, mm or µm
l Speed values in m/s, mm/s or µm/s
l Acceleration values in m/s², mm/s² or µm/s²
In translatory mode, you need to define the unit of length corresponding to one motor
revolution. Enter this value into the field Feed constant.
4.4.2.3 Other setting options
The area Display units enables the selection of various units (for rotatory or translatory
operation). You can define whether you want torque values to be displayed in A or Nm. For
the latter, tick the checkbox Torque in Nm. A prerequisite is a correct conversion constant
(AàNm) (button Factor).
In addition, the number of decimals for the position, speed and acceleration values can be
modified.
The selection of display units (including a transmission and feed constant) only affect the
indication of the values in the MetronixServoCommander
®
program.
The settings inside the servo drive will not be changed.
