any one can help to basic commisssionning parameter for 6ra80

SAYCOOO

Hello
thanks alot
the original problem was that the drive indicate alarm ( F42) which means tacho fault .
so i check the following:
• Open circuit in tachometer or pulse encoder cable.
• Tachometer of pulse encoder cable incorrectly connected.
• Pulse encoder supply has failed.
• Polarity for actual speed value (P743) is incorrectly set.
• Armature circuit data (P110 und P111) are incorrectly set (execute current controller optimization run).
• Tachometer or pulse encoder defective
• Pulse encoder supply voltage is incorrectly set (P140)
• The field polarity is not reversed by the external hardware when the field is reversed.

All privious ok and also i changed the encoder by new one but the same alarm displayed.

so that i changed the speed feed back from pulse encoder to emf controller.


if you please to fix the problem .
thanks
