Direct homing

Overview
With the "Direct homing" function, you traverse the drive to a defined home position without
using a higher-level control system. The drive itself controls and monitors the homing cycle.
Requirements
• Startdrive is in online mode.
• The "Basic positioner" function module is activated.
• The drive control panel is called and the master control is activated (see Chapter "Using the
control panel (Page 244)").
Procedure
To traverse the drive via the "Direct homing" function, proceed as follows:
1. Select the "Basic positioner" entry in the "Operating mode" drop-down list.
2. Select the "Direct homing" entry in the "Mode" drop-down list.
3. Click "1" in the "Switch on" field to switch on the motor.
The "Home position coordinates" entry is displayed.
4. Under "Home position coordinate", enter a value in LU/min and press the ENTER key. The
length unit is an internal length unit of the drive.
Note
You can also parameterize the home position coordinates directly at the homing settings of
the basic positioner.
5. Click the "Set" button to activate the home position coordinate directly.
Drive status
The status of the various parameters are displayed as LEDs at "Drive status".
Actual values
The values currently active in the drive are displayed at "Actual values" (actual values and current
values in the drive). In addition to the default parameter values, additional r-parameters are
available for free selection in two drop-down lists.
