Attention! During manual homing, do not reset the homing control signal (pa-
rameter
Start Homing (manual) 1235). The control signal must be
present until the "Homing Done" is signaled. Otherwise, homing is
stopped. Without successful homing, no positioning operation can be
started, i.e. error message "F1570 No Homing Done" will be displayed
if you try to start a positioning operation.
4.2.3 Homing mode
Via parameter Homing Mode 1130, you can define which signal will set the refer-
ence position, the direction in which the search for the point of reference is to be
started, as well as the condition for reversing the direction for the reference position.
Possible signals for setting the reference position:
− Negative hardware limit switch (anticlockwise)
− Negative hardware limit switch (clockwise)
− Home switch
− Zero pulse of an encoder
For the homing mode suitable for the relevant application, refer to chapter "List of
Homing Modes".
