UNINTENDED MOTOR MOVEMENT: THROUGH AN INVALID PARAMETERIZATION, THE COMMUTATION OF THE MOTOR IS CALCULATED INCORRECTLY |
|
oThis function may only be used by technically qualified personnel, who knows the system design and who can assess the consequences. oEnsure that no one is in the hazard area during the startup. oThe parameters EncoderGearOut and EncoderGearIn have to fit to the mechanical existing transmission between the motor and the encoder. oSet the parameter to not inverted / 1 for the Schneider-Electric servo motors of the series SH3, BSH, or BMH. |

Failure to follow these instructions can result in 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 EncoderGearOut 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).
Synchronous Motors with EncoderGearOut > 1
If EncoderGearOut > 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.
