Dear All
I work on commissioning a CNC milling machine having SINUMERIK 802C controller & GSK driver.
When I turn on the spindle automatically with M03 command the spindle starts running and then “Wait: for spindle ” message appeares on the HMI screen.
I thought that I should find an acknowledge signal from the spindle to the controller which says the spindle has reached to the desired speed; however I couldn’t find any signals on the input channel of PLC.
Can anybody kindly help me to find the cause and remedy of this problem?
Thanks,
