Operation mode "59 – Homing Done" can be linked to a digital output or a logic 
signal. 
Digital signal  Function
59 -  Homing Done 
Output signal if reference position is set (reference 
position defined
). This is done by homing or by tak-
ing over the current position as the reference posi-
tion. 
159 -  Inv. Homing Done 
Like operation mode 59, but with inverted output 
signal. 
Signal "614 – Homing Done" is available as an internal signal source for control func-
tions.
