Basic positioner (EPOS)
Overview
Position control means controlling the position of an axis. An "axis" is a machine or system
component that comprises the converter with active position control and the driven mechanical
system.
The basic positioner (EPOS) is a positioner integrated in the converter and calculates the
traversing profile for the time-optimized traversing of the axis to the target position for the
position controller. With the basic positioner (EPOS), the positioning tasks can be transferred
to the converter and thus relieve the higher-level control system.

Description of function
The following functions can be carried out by using the basic positioner:
• Limits
– Limiting the traversing range: specification of the possible traversing range through the
– Limiting the traversing profiles: restriction of the dynamic travel response through
• Monitoring
– Position/standstill monitoring: monitoring of the axis positioning motion and monitoring
– Following error monitoring: monitoring of the maximum deviation between the actual
