Axis - Homing configuration page

Configure the motion settings for the
Micro800
 controllers that support motion. Add an axis to create the axis configuration pages.
Use the
Axis<x> - Homing
 configuration page to do the following actions:
  • Configure the homing direction, velocity, acceleration, deceleration, and jerk for the axis.
  • Turn on the homing switch and set the active level.
  • Turn on the homing marker, select the available input variable, and set the active level.
Homing is a method of calibrating an axis to a known position. It involves moving the axis to a physically verifiable position, typically detected by external sensors and inputs. The system then designates a predefined position as the home position for the axis. The home position is the reference position for all absolute positioning movements, which is defined by
Home Switch Input
 and
Home Marker Input
 when turned on. The home position is set when the axis is started and is retained as long as the control system is operational.

Description
Homing direction
Specifies the direction in which the axis moves when returning to the home position.
Options are as follows:
  • Positive
     for clockwise
  • Negative
     for counterclockwise
The default setting is
Negative
.
Homing velocity
Specifies the homing velocity for the axis.
The value is in single precision floating format and is from 0.005 through 500.0 mm/s. The default value is 25.0 mm/s.
The value of
Homing velocity
 cannot be greater than the value of
Max velocity
 that is specified on the Axis
<x>
 - Dynamics configuration page.
Homing acceleration
Specifies how rapidly the velocity increases during the homing process.
The value is in single precision floating format and is from 0.005 through 50000.0 mm/s

The value of
Homing acceleration
 cannot be greater than the value of
Max acceleration
 that is specified on the Axis

 - Dynamics configuration page.
Homing deceleration
Specifies how rapidly the velocity increases during the homing process.
The value is in single precision floating format and is from 0.005 through 50000.0 mm/s

.
The value of
Homing deceleration
 cannot be greater than the value of
Max deceleration
 that is specified on the Axis
<x>
 - Dynamics configuration page.
Homing jerk
Specifies the rate at which acceleration changes.
The value is in single precision floating format and is from 0.0 through 50000.0 mm/s
3
. The default value is 0.0 mm/s

.
The value of
Homing jerk
 cannot be greater than the value of
Max jerk
 that is specified on the Axis
<x>
 - Dynamics configuration page.
Creep velocity
Specifies the creep velocity of the axis.
The value is in single precision floating format and is from 0.005 through 25.0 mm/s. The default value is 5.0 mm/sec.
The value of
Creep velocity
 cannot be greater than the value of
Max velocity
 that is specified on the Axis
<x>
 - Dynamics configuration page.
Home offset
Specifies the distance between the physical "home-sensor-on" position and the user-defined home position.
The value is in single precision floating format and is from –5368709 through 5368709 mm. The default value is 0.0 mm.
Home switch input
Turns on or turns off the home switch input settings. When turned on, the
Input
 and
Active level
 settings are available. It is turned on by default.
Input
 shows the input variable name for the home switch and the variable name is read-only.
Active level
 specifies the active level for the input signal from a hardware device, such as a switch. The active level is set as
High
 by default.
Home marker input
Turns on or turns off the home marker input settings. When turned on, the
Input
 and
Active level
 settings are available. It is turned off by default.
Input
 lists the available input variables for the home marker and supports up to16 inputs for selection even though the controller has more than 16 inputs available.
Active level
 specifies the active level for the input signal from a hardware device, such as a switch. The active level is set as
High
 by default.
