In homing mode 8, the end of travel limit switch triggers an immediate stop and then full reversal at high speed until Z-index is encountered and zero position is set. At this point the motor decelerates and stops.

Operation 1

  1. Homing operation is started, accelerate from LSPD to HSPD.
  2. Immediate stop when the end of travel limit switch is encountered.
  3. Reverse direction accelerating from LSPD to HSPD and move until specified number of Z-Index pulses are counted (ZCNT).
  4. As the specified number of Z-index pulses is encountered, zero position is set and deceleration to LSPD begins.
  5. Homing operation is completed by deceleration and stop.
  6. ERC pulse is sent.

Note: When utilizing the end travel limits, the ERC command clears the end-of-travel limit flag in the direction of the home during the homing operation. Refer to ERC command for further details.

Homing mode 24, Homing mode 8 at low-speed

In homing mode 8, the end of travel limit switch triggers an immediate stop and then full reversal at high speed until Z-index is encountered and zero position is set. At this point the motor decelerates and stops.


Operation 1

  1. Homing operation is started, accelerate from LSPD to HSPD.
  2. Immediate stop when the end of travel limit switch is encountered.
  3. Reverse direction accelerating from LSPD to HSPD and move until specified number of Z-Index pulses are counted (ZCNT).
  4. As the specified number of Z-index pulses is encountered, zero position is set and deceleration to LSPD begins.
  5. Homing operation is completed by deceleration and stop.
  6. ERC pulse is sent.

More information on the homing modes can be found in Section 5.5.5.1.1 of the PCL6046 users manual.
