ABB ACS 160 - Application Macro Positioning

ACS 160 User’s Manual 43
Application Macro Positioning
This macro is intended for simple positioning tasks. The default operation is appropriate for conveyor
systems where items are repetitively moved a certain distance in the same or opposite direction.
Distance is measured by calculating pulses from an encoder. When the distance has been travelled
i.e. desired position reached, the drive stops and waits for a new start. Simultaneously, the output
relay activates signalling that target position has been reached, refer to Figure 2.
Homing is an additional configurable feature selected with parameters. Homing means that the load
is driven at slow speed to known position (home position).
The value of parameter 9902 is 14 (
POSITIONING).
Connection example.
Note! After selecting the macro, turn power off and then on again.
• The encoder should be mounted on the axis of the motor.
• Use parameters 8207 - 8210 to adjust the target positions according to the application.
• Described default functionality is valid from ACS 160 SW version 1.0.0.F.
