There are four hall-less commutation options available:
Optimum search 1 | Commutate the motor using a minimum motion algorithm the first time the drive is enabled following power-up. |
Stepper open loop search 1 | Commutate the motor by forcing the motor's electrical angle the first time the drive is enabled following power-up. The motor will move up to one electrical cycle. |
Optimum search 2 | Commutate the motor using a minimum motion algorithm every time the drive is enabled. |
Stepper open loop search 2 | Commutate the motor by forcing the motor's electrical angle every time the drive is enabled. The motor will move up to one electrical cycle. |
Prior to firmware version 2.00, when using hall-less commutation, the P Drive will generate an AL-31 alarm if none of the hall inputs are connected. To prevent this from happening, place a jumper between pin 5 (hall phase U) and pin 7 (digital ground) on the drive's feedback port.
