The EL2522 incremental encoder simulation terminal (pulse train) outputs a frequency-modulable 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. The pulse sequence and pulse number can be specified directly via the process data in the frequency. Alternatively, the integrated path 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 EtherCAT Terminal can control three output channels in the ABC encoder simulation.

Special features:

• Pulse train (frequency output), RS422
• Different operating modes
• Frequency modulation
• Pulse direction setting
• Incremental encoder simulation (1x ABC, 2x AB)
• Integrated path control
• Synchronized operation through distributed clocks XFC technology possible
