Hi All,
I'm having a PHNC alarm (2091)
when i go to phnc screen it gives me the following:

(1/2)
--Message : top dead center sensor alarm
--details : no TDC signal came up despite the ram is in that position
--solution : check the TDC sensor, then press the reset button

(2/2)
--message : 09 servo alarm
--detail : the servo tolerance is over the limit, while the punch is idling
--solution : check hydraulic unit, servo valve and servo amplifier

I also reinitialized the PHNC but still got the alarm, so if you can help me on this I will appreciate it a lot and thank you very much.
this is my email address:
