CJ1W-CTL41-E

CJ1W-CTL41-E Get the right position The new CJ1W-CTL41-E counter unit provides easy connection of up to 4 incremental encoders or high-speed pulse-train inputs to any CJ1 PLC system. Encoder inputs Flexible Incremental encoders remain the most economical way to accurately Linear or circular counter modes can be selected for each channel acquire fast-changing position data in machine automation. individually. And besides processing A/B/Z or quadrature encoder These encoders provide speed, direction and position information signals, each channel can also be configured for up/down pulse through quadrature outputs consisting of phase-offset A- and counting, or pulse+direction signals. Reconfiguration of counter B-pulse signals. Optionally, there may be a Z-pulse or index signal properties, like ranges or comparison values or control hysteresis, to mark the encoder’s ‘zero’ position. can be made on-the-fly by issuing commands from the PLC program. For efficient commissioning and troubleshooting, the unit has With the addition of the CJ1W-CTL41-E 4-channel counter unit, an internal error log of 30 messages that can be accessed from Omron’s powerful CJ1 Programmable controller range now offers CX-Programmer, Omron's universal PLC programming software. a wide choice of functionality and performance levels to choose from, to always exactly meet your application’s needs; up to 24 of these Easy to connect units can be controlled by a single CJ1 CPU. To provide fast and easy connection of any incremental encoder to the new 4-channel counter unit, there is a new optional terminal block. Fast response This links to the CJ1W-CTL41-E by means of a standard 40-point cable, The A/B/Z counter inputs of the CTL41-E can process pulse signals available in several standard lengths. Conveniently grouped terminal up to 100 kHz, effectively allowing count frequencies up to 400,000 blocks allow full wiring of A/B/Z and power supply for 4 encoders, counts per second on all 4 channels simultaneously. The resulting at either 24V- or line-driver signal levels. Screwless technology will counter data is copied to the CPU each PLC scan cycle as four 32-bit reduce the time required for installation and maintenance, and values. By internally comparing the counter values with 8 preset assure that even thin-gauge encoder wires are reliably connected, values (or 4 ranges) per channel, the CTL41-E can also issue even under harsh vibration conditions. interrupts to the CPU for sub-millisecond response. Functionality CJ1 encoder input units CJ1M-CPU21/22/23 Servo positioning Compare + on/off control CJ1W-CT021 Compare + Interrupt CJ1W-CTL41-E Input only CJ1W-CTS21-E 2 CJ1W-CTS21-E: Number of axes per unit 4 2-channel SSI-encoder interface unit.
