CS1W-MC421/-MC221
Motion control units
High-precision, motion controller with multitasking G-language programming
• High-speed control of up to 4 axes with one unit and
up to 76 axes with one PLC (19 units x 4 axes)
(assumes that power supply unit capacity is not
exceeded).
• Winding operations easily controlled at high-speed
using traverse positioning control.
• High-speed response to commands from CPU unit
(8 ms for 2 axes, 13 ms for 4 axes).
• Encoder response of 2 Mpps possible with 4x
frequency multiplication for applications with highspeed, high-precision servo motors.
• D interrupt code outputs to CPU unit at end of
positioning or at specified positions (D code output
time: 3.3 ms max.).
• CX-motion Windows-based support software
define user mnemonics to use in place of G codes
to simplify MC program development and analysis.
• Servo trace function from CX-motion to trace error
counter changes or motor speeds.
• Automatic loading function
MC programs and positioning data can be automatically downloaded from computer memory when
required by the MC unit.
Motion controllers
Function
The motion controller provides closed-loop motion control via an alog outputs for up to 4 axes, and supports the G language for
advanced, high-speed, high-precision position control. Multi-tasking allows you to run the axes independently for a wider range of
application.
