Hi
Any ideas on this fault.
Machine starts up. Machine can be calibrated, runs backward ok, if tried to run forward Machine shuts down. If no no forward motion attempted Machine clamps and cuts ok. Any attempt to move backgauge forward, Machine shuts down
Here's hoping

Hi Sir:

Try to test the limit switch under the table, for loose wires, bad contacts, or faulty L. Switch,

2) contactor reverse, faulty, bad contacts, or loose wires, or lack of power lines: l1+l2+l3.

3) Brake, and clucht dirty, or bad adjusted, dirty, adjust, and look fo the belt. Test the motor of backagauge , if voltage is o,k

Blessing.

Hi, before calibrating it worked fine forward and backward, no problem. When it displays 50 cm, the forward gear is blocked

Review, as I did explain limit switch, under table.

Sounds like a bad contactor. Check k70, k80, k90, k100. One of them is probably welded shut.
