Error description 280-089A
Error message
No safety clearance on the inside
Cause of error
No safety clearance on the inner side.
No safety clearance was programmed at the inner side of the grinding wheel. When the dresser approaches the grinding wheel, it moves toward the wheel edge up to a safety clearance. To ensure that the diamond does not touch the wheel at this position,
the safety clearance must be at least as large as half the dresser width.
Error correction
Define a safety clearance on the inner side.
