Hi,

Set P1800 = minimum 6kHz (for 400Hz operation)

What is P719 set to?

Look at r1050 and see if this is changing when you are using the UP & DOWN buttons on the BOP.

To prove the correct operation of the MOP using the UP & DOWN buttons:

Change P1080 = 90Hz and run the drive - see if you can change the speed.

If correct, then you only have a speed limitation somewhere.

When we know the answers here, we can go further

Regards,

Graeme

I forgot to ask: What is the setting in P1300, also, does P3900 still = 3, or does it set back to 0?

Hi, strange that the MOP output does not change.

When you set P700 = 1, then automatically, P1035 = 19.D and P1036 = 19.E

Can you check these and look at r1050 again when the drive is running, the output of the MOP MUST change when you alter the buttons on the BOP.

Graeme

Hi, I would have expected P719 = 11 (This is based on BOP control for ON/OFF and Setpoint from UP & DOWN buttons)

Okay, so now I'm lost.

r1050 = 5Hz, but before = 40Hz
