Siemens 17900 - Block motion synchronous action: axis is not a machine axis

At this point, the block context calls for a machine axis. This is the case with: - G74 (reference point approach) - G75 (fixed point approach) If a geometry or additional axis identifier is used, then it must also be allowed as machine axis identifier (MD10000 $MN_AXCONF_MACHAX_NAME_TAB) Control reaction: NC Start disable in this channel. Interface signals are set. Alarm display. NC Stop on alarm.

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.

Common Causes

  • At this point, the block context calls for a machine axis.
  • This is the case with: - G74 (reference point approach) - G75 (fixed point approach) If a geometry or additional axis identifier is used, then it must also be allowed as machine axis identifier (MD10000 $MN_AXCONF_MACHAX_NAME_TAB)

Troubleshooting Steps

  1. 1Use machine axis identifier when programming.
  2. 2Clear alarm with the RESET key. Restart part program Continuation: Alarms
