2.5.6 Homing
This function can be used to perform homing. The drive moves in a preselected mode and
calculates the zero position (home) automatically on the basis of a home mark before declaring
this value to the drive control. All position data refers to this home position.
Homing is generally
performed once following mains connection.
The following can be used as home mark signals:
• Zero pulse (signal edge from encoder system for position actual value, one per
motor revolution)
• Touch probe (signal edge at corresponding touch-probe input of PLC)
• A preliminary stop position can be set via a homing switch. In this case, home will be the
next zero position of the actual value encoder on the motor or the next touch probe
(depending on the selected mode).
