Introduction of PR Operation ASDA Series Application Note after homing will be identical. Ignore Y Z Pulse PL Signal Figure 1.22 Homing Path when Taking Z Pulse as Reference 1.2.2.4 Reference to the Falling-Edge Signal on Home Sensor (P5-04.X=6: move forward to look for the falling edge signal of home sensor; P5-04.X=7: move backward to look for the falling edge signal of home sensor) This homing method is to take the falling edge signal of home sensor as reference. After home sensor has detected the signal, Z pulse can be also regarded as homing origin.
Limit Stop or Go back ORG ON -> OFF Go backward to look for Z Go forward to look for Z Ignore Z Figure 1.23 Taking the Falling-edge Signal of Home Sensor as Origin Signal See the example in Figure 1.24. The motor returns and looks for Z. When homing command is issued, the motor’s position is at S1 and the sensor board has not passed through the home sensor. At this stage, motor will operate at high speed first; as soon as it encounters the rising edge signal of ORG sensor, motor will then switch to low speed. When encountering the failing edge signal of ORG sensor, motor will keep operating at low speed to look for Z pulse; it then slows down and stops at position E upon finding Z signal.
