recently purchased this machine used and just getting it started up. The machine was running fine and during a cycle that was drilling a couple hundred holes (about 50 holes in) it alarmed out with a 5381 Invalid command in FSC mode, An attempt was made to issue the following commands: When the reference position for the master axis under flexible synchronization control has not been established, G28 command for the master axis.

The program had completely ran a couple times and then on the third cycle after about 50 holes in it gave this alarm and stopped. It now will not run any programs and immediately gives this alarm no matter which program you call up. Currently stuck and any help would be greatly appreciated.
