Limits
Edit the Limits parameters based on the table below.
Table 30 - Motor and Load Parameters
Parameter
Description and Values
User-defined Unit
Defines user unit scaling that matches your mechanical system values. These units
shall be carried forward into all command and monitor axis in user unit values
throughout programming, configuration, and monitoring functions.
Position
Select from any of the following options:
– mm
– cm
– inches
– revs
– custom unit (ASCII format of up to 7 characters long)
Time
Read only. Predefined in seconds.
Motor Revolution
Defines pulse per revolution and travel per revolution values.
Pulse per Revolution
(1)
(1) The parameter is set as REAL (float) value in Connected Components Workbench. To learn more about conversions and
rounding of REAL values, see
Real Data Resolution on page 187
Defines the number of pulses needed to obtain one revolution of the drive motor.
Range
: 0.0001…8388607
Default
: 200.0
Travel per Revolution
(1)
Travel per revolution defines the distance, either linear or rotational, that the load
moves per revolution of the motor.
Range
: 0.0001…8388607.
Default
:1.0 user unit.
Direction
Defines polarity, mode, and change of delay time values.
Polarity
Direction polarity determines whether the direction signal received by the
controller as a discrete input should be interpreted on the input as received by the
motion controller, (that is, the non-inverted case), or whether the signal should be
inverted prior to interpretation by the motion control logic.
Set as Inverted or Non-inverted (default).
Mode
Set as Bi-directional (default), Positive (clockwise), or Negative (counter-clockwise)
direction.
Change Delay Time
Configure from 0…100 ms.
Default value is 10 ms.
A red border on an input field indicates that an invalid value has been
entered. Scroll over the field to see tooltip message that will let you know
the valid value range for the parameter. Supply the valid value.
ATTENTION:
Modifying Motor Revolution parameters may cause axis
runaway.
