Siemens 10870 - Block facing axis for constant velocity not defined

Constant cutting speed was selected although no transverse axis was applied as reference axis for constant cutting speed or assigned through SCC[AX]. Constant cutting speed can be activated as follows: - Basic position G96, G961 or G962 of G group 29 during booting - Programming of G96, G961 or G962 A reference axis for G96, G961 or G962 can be applied as a transverse axis in MD20100 $MC_DIAMETER_AX_DEF or defined through the instruction SCC[AX] Control reaction: Correction block is reorganized. Local alarm reaction. Interface signals are set. Alarm display.

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

  • Constant cutting speed was selected although no transverse axis was applied as reference axis for constant cutting speed or assigned through SCC[AX].
  • Constant cutting speed can be activated as follows: - Basic position G96, G961 or G962 of G group 29 during booting - Programming of G96, G961 or G962 A reference axis for G96, G961 or G962 can be applied as a transverse axis in MD20100 $MC_DIAMETER_AX_DEF or defined through the instruction SCC[AX]

Troubleshooting Steps

  1. 1Please inform the authorized personnel/service department.
  2. 2Check MD20100 $MC_DIAMETER_AX_DEF.
  3. 3Before programming G96, G961 or G962 a transverse axis must be defined as a reference axis for constant cutting speed via MD20100 $MC_DIAMETER_AX_DEF or SCC[AX].
  4. 4Clear alarm with NC START or RESET key and continue the program
