Eliminating Radial Movement in the Turret During Clamping and Unclamping

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

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.

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.

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.

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.
