Package includes: 1 x 100PPR trailer hand wheel MPG. 1 x 4-axis CNC offline motion controller DDCSV3.1 1 x 4GB USB Flash Drive 1 x USB extension cable. User manual will be sent by email. Controller Specification: Adopts the ARM + FPGA design framework. ARM Controls The human-computer interface and code analysis as well as the FPGA provide the underlying algorithms and generate the control pulse. The internal operating system is based on Linux. Can be used for CNC machines. Lathes, cutters, pick & place and mills etc. and work as a standalone system without a computer. Ensures high precision, accuracy and reliability. Support the operation of quick indication of the running position. Support for recovery after a power failure. Data is automatically saved. Supports NPN type switches only The main control equipment is a 24V power supply. The current capacity must not be below 0.5A. Supports the USB flash drive to read the G code, and the size of the G code file is not required. Mode: 3 kinds of testing modes: fixed position of tool sensor, floating position of tool sensor, rectangular block sensor Improved the software, added many parameters, optimal design and algorithm Handwheel specification: CNC system and position control of various mechanical devices.
