Nakamura TW20, Fanuc 16TT, need parameter to lock/unlock turret manually

[aj]

Greetings everyone.

I have a Nakamura TW-20 (Fanuc 16TT) with a hydraulic leak out of the back of the turret. I'd like to put the machine in maintenance mode and manually lock and unlock the turret to see if the oil leak is related to the turret clamping pressure.

On our WT-150 and WT-250 machines (Fanuc 18i) I can change data parameter D145 to lock and unlock the turret using the Block Delete switch. I'd like to be able to do that on the TW machine.

I tried D145 on the TW but it didn't do anything.

Anyone know the param I need to change? Is it even possible to do what I'm trying in this machine?

Thanks in advance.

can you just manually cycle the hydraulic valve to unclamp the turret?

Heard from my tech friend at Method's. There's no provision for me to do what I'm trying to do. The TW20 has a "lift and turn" turret. No hydraulic pressure keeping it closed.

Thanks anyway guys.
