A
  • Cause

    Sensor does not detect chuck CLAMP/ UNCLAMP for specific time at model with sub spindle sensor

  • Solution

    Adjust sensor position and check for sensor operating status

A
  • Cause

A
  • Cause

    Exceeded point set at D1300 when S/R Base #1 is unclamped.

  • Solution

    Move Z AXIS toward ‘-‘direction in [JOG], [RPD] mode.

A
  • Cause

    Exceeded point set at D1304 when S/R Base #1 is unclamped

  • Solution

    Move Z AXIS toward ‘+‘direction in [JOG], [RPD] mode.

A
  • Cause

    M179 (S/R Base #1 Unclamp), M178 (S/R Base #1 Clamp) is not completed in 30 seconds.

  • Solution

    1. Z AXIS did not move to coupling position with S/R Base #1 after M Code command: position of S/R Base #1 is not correct. Do S/R Base #1 position reset. 2. Z AXIS connecting pin at S/R Base #1 won’t operate after Z AXIS TRAVERSE: Check hydraulic line at

A
  • Cause

    It is clamped without Clamp command during S/R Base #1 Unclamp in Mode besides [ZRN] Mode

  • Solution

    1. IF Pin is coupled with Z AXIS, check for Pin position limit S/W (X5.6, X5.7). 2. If Pin is not coupled with Z AXIS, check for hydraulic pressure. set S/R Base #1 position after alarm release for safety.

A
  • Cause

    M179 (S/R Base Unclamp) command is given when it is not allowed.

  • Solution

    Check for the following status. - zero position of X AXIS - all Spindle stop status - Door is closed when Door Interlock Key S/W is ON
