Figure 18: Home Move Sequence
Rotary Application
This example uses an external sensor and the motor’s encoder marker pulse to establish a home reference position.
Figure 19: Home Sensor and Marker then Offset, Example
When the drive sees the rising edge of the Home Initiate function, it accelerates the motor to the Home Velocity. The motor continues at that
velocity until it first senses the Home Sensor input. The motor continues on at the home velocity until the marker is activated.
The rising edge of the motor’s encoder marker channel is used to establish the reference position.
After sensing the rising edge of the motor’s marker channel, the drive will continue moving and will decelerate to a stop at the specified offset
position.
