altivar28 drive

Hello
this drive runs fine till yesterday and stopped
It displays "ready", the potentiometer is fine; the I/O contact and the 24v circuit are also ok
When the contact is "ON" the display remain "ready" and the motor don't start
I've turned the drive to it's default parameters and entered the motor's one; but the default persist
I've verified the hardware side for jumper but there are no jumpers
I'm really stuck
Please can someone help me
Best regards

Couldd it possibly be in keypad or "local" control, thus ignoring the terminal strip signals? Try starting it from the keypad. If it starts, the control is in the wrong place.
