Figure 17: Home on Sensor Scenarios
The illustrations show the position which is defined as Home Position, with the Home Done signal set. The function to be executed after
finding the home position is configurable via parameter 5.17.2.12 Function after Home Found, with the following selections:
Selection
Speed Stop
Position Stop
Home on Block
Home on Block enables homing without a sensor for machines that can run against an end mechanically blocking the movement.
Searching for the block is done with speed, ramps, and direction configured with parameters 5.17.2.6 Home Speed, 5.17.2.8 Home Ramp
Selection, and 5.17.2.4 Home Search Direction. The block is detected by using the home torque limit, set with parameter 5.17.2.9 Home
Torque Limit while the motor is at standstill. Adapt the home torque limit accordingly so it will not damage the machine. Actual Position
is set to the value of parameter 5.17.2.5 Home Position and the Home Done signal is set when a block is detected.
