EL2522 | Incremental encoder simulation terminal (pulse train)
The EL2522 incremental encoder simulation terminal (pulse train) outputs a signal that is modulated via the frequency signal on two channels with four outputs. The signal can be used to control motor drivers or other signal receivers, which are controlled by single cycles. As with the EL2521, the pulse sequence and pulse number can be directly specified via the process data in the frequency. Alternatively, the integrated travel distance control can be used. For each channel the operating mode (frequency modulation, pulse/direction specification and incremental encoder simulation) can be selected. In addition, the EL2522 can control three output channels in the ABC encoder simulation.
