1. 4 Axis PLC Controller 500KHz off-line

RMHV2.1 is the 4 axis and 4 axes motion controller which has been researched and developed by RATTM MOTOR CNC for four years. The control period of each position is only 4 milliseconds, with a high control precision. The highest uniaxial output pulse is 500KHz and the pulse width can be adjusted. It supports the common stepper motor and servo motor.

RMHV2.1 numerical control system adopts the ARM+FPGA design framework. The ARM can finish the part of human-computer interface and code analysis and the FPGA can finish the part of underlying algorithm and control pulse generate, with the reasonable design, reliable control and easy operation.

The panel layout structure of RMHV2.1 is rational. The CNC MOTION SYSTEM Controller can be finished only by 17 keys and it supports the FANUC with high universality to be compatible with G code set.

This manual introduces the operation method of the RMHV2.1,the machine tool and the operation procedure of the machine tool. By lots of graphical representation and examples, the uses can quickly learn to use the RMHV2.1CNC system.
