Got a fanuc control on a colchester 4000 with the following errors due to cable disconnection.

Parameter 21 reads 00000011
Parameter 22 reads 00000000

I have cleared the 310 and 320 by changing parameter 21 to 00000000 and parameter 22 to 00000011. The machine now goes into overtravel error on the Z axis with loads of travel still available. Can any one help Thanks

Usually push Cancel & P button while powering up, this should cancel the software OT's.
