UNINTENDED MOTOR MOVEMENT: INVALID PARAMETERIZATION, OR INCORRECTLY CALCULATED COMMUTATION OF THE MOTOR |
|
oDo not use this function unless you are technically qualified and properly trained personnel, capable of accessing the consequences of its use. oEnsure that no one is in the area of operation during the startup. oEnsure that the parameters EncoderGearIn and EncoderGearOut correspond to the mechanical transmission between the motor and the encoder. oSet the EncoderDirection parameter to not inverted / 1 for the Schneider Electric servo motors with internal encoders. |

Failure to follow these instructions can result in death, serious injury, or equipment damage. |
The EncoderGearIn / EncoderGearOut parameters describe a gear factor between motor and encoder. This gear factor can be different from the gear factor between motor and load (parameter GearIn / GearOut).
The parameter EncoderGearIn indicates the number of teeth on the motor side.
NOTE: The parameter is supported as of version V01.36.xx.00.
NOTE: Modifications to the parameter are only applied during the Sercos phase up (communication phase 0 => communication phase 4).
This parameter has no effect for asynchronous motors in open-loop V / f mode (ControlMode = open-loop control / 1) or encoderless velocity control (ControlMode = Encoderless velocity control / 2).
Synchronous Motors with EncoderGearIn > 1
If EncoderGearIn > 1 is set, then the commutation of the motor that is saved in the motor nameplate is not evaluated. Saving the commutation into the motor nameplate with the object parameter MotorCommutationControl is not possible. The commutation has to be determined over again every time the drive is newly switched on or reset.
