Just got myself a little 85 ht20 hitachi with a fanuc 10t control. I have noticed that the hyd pump cuts out when the machine is just sitting as an example I was loading tool offsets jogging the turret around and the pump cut out.
The control shows no alarms at all
The hyd pump can't be restarted by pressing the standby button or by hitting estop then resetting the estop and pressing the standby button.
The only way I can restart the hyd pump is to turn off the control and restarting it.
It is nearly like there is a broken wire to the pump or similiar.
Any ideas? I have only run a couple of small programs and it has not cut out mid program
