Sinumerik Alarm 20055 Channel %1 master spindle not present in JOG mode
%1 = Channel number
The displayed axis is to be traversed as machine axis in JOG mode with revolutional feed, but no master spindle has been defined from which the actual speed could have been derived.
– Alarm display.
– Interface signals are set.
– Local alarm reaction.
Please inform the authorized personnel/service department. If the revolutional feed is also to be active in JOG mode, then a master spindle must be declared via the channel-spe- cific machine data 20090 SPIND_DEF_MASTER_SPIND. In this case you have to open a screen in the PARAMETER operating area with the soft keys “SETTINGDATA” and “JOG DATA” and preselect the G function G95 there. The JOG feedrate can then be entered in [mm/rev]. (If 0 mm/rev is set as JOG feed, the control takes the value assigned in the axis- specific MD 32050 JOG_REV_VELO or in the case of rapid traverse overlay 32040 JOG_REV_VELO_RAPID). The revolutional feed in JOG mode is deactivated by changing the G function from G95 to G94.
Clear alarm with the Delete key or NC START.
