Introduction

This guide will explain how to remove radial movement of turret when clamping and unclamping.

    • This shows slight angular movement of the turret when it clamps and unclamps to move to the next station.

  1. Removing tools from the turret is not necessary for re-referencing the turret.
    • Removing tools from the turret is not necessary for re-referencing the turret.

    • Set Manufacture Password.

    • Index turret to Position 1.

    • Go to [Machine], On the MCP, press [JOG] and [REF POINT].

    • Read the angle reported for MQ1—this is your Q-axis.

    • The Q-axis represents the degree of rotation of the turret. At Position 1, the greater the Q-axis angle is from zero, the more radial movement there is when clamping and unclamping. Position 1 should be nearly or at zero.

  2. On the control, go to [Diagnostics] → [Version].
    • On the control, go to [Diagnostics][Version].

    • Locate the PLC User Program version.

    • If version starts with 05.XX.XX, it is New-PLC.

    • If version starts with 01.XX.XX, it is Old-PLC.

    • This determines which DB address to use in Step 4.

  3. Go to [Diagnostic] → [NC/PLC Variable]
    • Go to [Diagnostic][NC/PLC Variable]

    • In an empty row under Variable, enter the proper bit:

    • Old-PLC → DB34.DBX4.7

    • New-PLC → DB37.DBX4.7

    • Set the Format to [B].

    • On the MCP, press both [JOG] and [REF POINT].

    • Press [Change], enter 1, then press [Input][OK]

    • The bit will toggle back to 0 automatically.

  4. While still at Position 1, verify MQ1 now reads 0.0°.
    • While still at Position 1, verify MQ1 now reads 0.0°.

    • Jog the turret to several positions.

    • Confirm radial movement during clamping/unclamping is gone.

    • Power cycle the machine to complete the reset.
