SYSMAC CJ-series CJ1M CPU Units (with Built-in I/O) CJ1M-CPU2@ CSM_CJ1M-CPU2_DS_E_2_1 Compact, Applications-oriented Controllers with Built-in Pulse I/O for High Potential * The compact, high-potential SYSMAC CJ1M PLCs provide built-in pulse I/O for high-precision performance * Pulse I/O for two axes to achieve higher machine precision. CJ1M-CPU21 Features Two 100-kHz Pulse Outputs * Use special instructions to easily implement various types of positioning, such as positioning with trapezoidal acceleration/deceleration, positioning with different acceleration/deceleration rates, and triangular control. * Combine positioning instructions to handle many different applications, such as interrupt feeding and target position changes during positioning. * Pulse startup is as fast as 46 s and is 70 s even for trapezoidal acceleration/deceleration. Two Pulse Inputs * Two high-speed counters and four interrupt inputs are also built in. The high-speed counters operate at up to 100 kHz for single-phase and 50 kHz for differential-phase operation. These inputs enable controlling with high-speed response.
