Siemens 61603 - Block : Recess type incorrectly defined
Alarm 61603 is triggered by CYCLE93 (groove/recess cycle) when the groove geometry parameters are geometrically incompatible. The radii or chamfer dimensions at the groove base exceed or conflict with the groove width, or a face groove has been programmed parallel to the longitudinal axis where only peripheral grooves are permitted.

Siemens 61603 - Block : Recess type incorrectly defined
Block: Recess type incorrectly defined
Radii/chamfers at the groove base do not match the groove width. Face groove on a contour element running parallel to the longitudinal axis is not possible
Root Cause Summary
Alarm 61603 is triggered by CYCLE93 (groove/recess cycle) when the groove geometry parameters are geometrically incompatible. The radii or chamfer dimensions at the groove base exceed or conflict with the groove width, or a face groove has been programmed parallel to the longitudinal axis where only peripheral grooves are permitted.
Safety
- Only qualified personnel should diagnose and clear control alarms; follow the machine builder's safety procedures and lockout/tagout where hardware work is required.
Causes and Fixes
- 1
Access CYCLE93 call in NC program and verify groove width parameter WG is correctly specified. Cross-reference SINUMERIK documentation VARI. 2-558 for valid range.
- 2
Check corner radius RV and chamfer CHF parameters. Ensure RV and CHF values are each less than WG/2. Recalculate based on actual tool geometry and groove geometry.
RV and CHF cannot be combined in the same groove definition; select one only.
- 3
Re-simulate cycle using Siemens ShopMill or SINUMERIK Operate simulation to verify tool path before uploading to machine.
- 4
Upload corrected NC program and execute CYCLE93 step-by-step using single-block mode (MDI or JOG) to monitor alarm resolution.
