Core functionality
Dual axis servo control
Digital mode: Control GE Fanuc digital AC servo; Servo loop update: torque 250 μ s, speed 1ms, position 2ms
Simulation mode (firmware ≥ 1.40): Output ± 10V speed command, drive SL series or third-party analog servo, position loop 2ms update
Support standard positioning mode+Follower electronic tracking (electronic gear) mode, spindle connected to incremental encoder
Onboard DSP, independently executes motion contours without occupying PLC CPU resources; Block processing time<5ms
Flash non-volatile storage: 10 sets of motion programs+40 subroutines, motion programs stored locally in the module, PLC only performs interactive triggering
I/O resources
Each axis: origin, positive and negative overtravel inputs; 2-channel position latch trigger input
Follow the spindle: Orthogonal incremental encoder interface
Auxiliary 13 bit analog output, servo tunable monitoring
Panel RJ-11 RS-232 port (cable IC693CBL316): APM motion software download program, firmware upgrade Qualitrol
Automatic data exchange between PLC and DSM modules, without the need for users to write transmission logic
