please help have had to do a memory clear on my T21i-D so now need to re enter my O9000 programs

I have changed PWE to 1 then turned off and back on again but when I try to change parameter 3202 bit 4 (NE9) from 1 to 0 I get a WRITE PROTECTED alarm

how do I get over this

I have changed PWE to 1 then turned off and back on again?

Put PWE to one and just leave it on, you must be in MDI to edit parameters. Some machines also need to be in Estop.

Put the emergency stop and then you try to change the parameters.

leave PWE on 1 and DO NOT power off. if you power off, the machine will re-set PWE to 0.
Set mode to MDI, Set PWE to 1, change the parameters then after you have finished, power the machine off then on.

1. MDI - Settings - PWE=1 (Alarm P/S100 flashes as warning that PWE is ON... you can ignore this).
2. System - PARAM - key in 3202, press [NO. SRH] - cursor over to bit 4 and set it = 1.
3. Go back to Settings and turn PWE = 0, then RESET to clear the alarm - no need to power off.

Re-enter O9000 programs.

After you've finished, repeat steps 1, 2 (set 3202 bit 4 = 0, and 3 - still no need to power off.
