error 403, 444 and HCAL

Dear all,
I have a CNC punch machine: Murata Weideman Magnum 5000 with Fanuc control series 0
I am in a trouble follow as:
When i press "Zero Set", after X,Y,T axis go home then C axis go home so on the screen, the error immediately occur: 403 Servo (VRDY OFF) and 444: C servo dection ERR.
In the DGN 723 for 4th axis (= C axis) bit 4 =1 is mean: HCAL alarm.
I checked cable, driver, reaplce motor so seemingly every thing is okay.

And i want to know the reason why when power on, with C axis, i can rorate it by hand while i can't do it with X,Y,T . Is there a parameter or signal effect "Servo ON" of C axis?

Thanks for your reading.
