Operation with encoder
During the operation with encoder the actual position value of the motor is supplied as real actual value to the position controller. This is adjusted during the configuration of the drive. The encoder input of the axis is linked with the encoder terminal and not with the position feedback of the stepping motor terminal.
An incremental encoder can be connected directly to the terminal KL2541. The terminal has to be parameterized in that way, that it insert the encoder signal into the output process image.

Also during the operation with encoder a stepping motor can loose steps or stops moving at dynamic overloading (loosing synchronism of the stepping motor). And also here the dimensioning and parameterization of the dynamic parameters of the motor has to be done with special care.But in contrast to the operation without encoder the use of position lag monitoring is possible. |
