Code 16017: Channel %1 Axis %2 Identifier %3, LIFTFAST ignores this axis, current axis not capable of retraction

Issue Description & Safety Warning

The Siemens SINUMERIK 840D CNC has triggered a critical Channel %1 Axis %2 Identifier %3, LIFTFAST ignores this axis, current axis not capable of retraction alarm. Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.

Official Troubleshooting Steps

Parameters: %1 = Channel %2 = Axis, spindle %3 = Identifier Definitions: LIFTFAST cannot be applied to the axis. Alarm can be suppressed via MD11415 $MN_SUPPRESS_ALARM_MASK_2 bit 11. Identifiier (parameter 3) is bit-coded and di splays some possible causes for the alarm: 0x01Axis is in another channel 0x02Axis is in spindle mode (e.g. SPOS) 0x04Axis is PLC axis 0x08Axis is o scillating axis 0x10Axis is neutral axis 0x20Axis is coupled slave axis 0x40Axis is in static synchronized action Overview of reactions of co mmon programming to LIFTFAST: Axis | Synact | Reaction to LIFTFAST ----------------------------------------Path | | STOP + LIFTFAST POS | | STOP + LIFTFAST POS | non-modal | STOP + LIFTFAST POS | modal | STOP + LIFTFAST POS | stati. | RUN + SHOWALARM 16017 POSA | | STOP + LIFTFAST MOV | non-modal | STOP + LIFTFAST MOV | modal | STOP + LIFTFAST MOV | stati. | RUN + SHOWALARM 16017 PLC | | RUN + SHOWALARM 16017 Oscill. | | RUN + SHOWALARM 16017 SPOS | | STOP + SHOWALARM 16017 SPOS | non-modal | STOP + SHOWALARM 16017 SPOS | modal | STOP + SHOWALRAM 16017 SPOS | stati. | RUN + SHOWALARM 16017 SPOSA | | STOP + SHOWALARM 16017 Reaction: Alarm display. Remedy: Remove axis from POLFMLIN or POLFMASK. Alarm can be suppressed via MD11415 $MN_SUPPRESS_ALARM_MASK_2 bit 11. At the time of LIFTFAST, an axis for LIFTFAST is programmed, but the status of the axis does not allow LIFTFAST (e.g. oscillating ax is or spindle), or the axis is not in the channel. LIFTFAST should only be applied to those axes that are capable of retracting at that time; POLFMASK or POLFMLIN should be adapted accordingly. Program Continuation: Clear alarm with the Delete key or NC START. Diagnostics Manual (DAsl), 03/2009
