GH series motion controllers are designed for high-speed and high-accuracy motion control. GH-800 motion controller can control 8 servomotors, applicable to the fields with higher requirements for speed and accuracy, such as medical treatment equipment, semiconductor manufacturing and high-accuracy test equipment.
Adopt high-performance 32-bit floating point DSP (120 MELOPS), FPGA and FLASH technology.
Control 8 servo axes simultaneously
Programmable servo period with an updating rate of 5 ?C 10kHz.
Motion ways: point-to-point motion, linear interpolation, circular interpolation, velocity control, electronic gear and intellectual home point searching.
Motion modes include the programmable asymmetrical T-curve and S-curve modes.
For all the motion modes, the motion parameters can be modified on the fly.
The auxiliary encoder on board can realize dual close loop feedback control.
All the position registers and parameter registers are all of 32 bits.
Control strategy: PID (Proportional-Integral-Derivative) + VFF (Velocity Feed Forward) + AFF (Acceleration Feed Forward) with low pass filter, band with pass filter and bias compensation.
Cascade PID filter with the derivative gain filter and integral limit, as well as the dual position close loop feedback function (optional).
Process the external events in synchronization. Provide uncommitted high-speed digital I/Os, which can be used in capturing position, comparing position, and generating pulse signal.
The motion monitoring system can get the target velocity, motion completion, and reference velocity and reference position information.
Automatic home point searching function
Automatic stopping function.
User defined coordinate system for ease of programming.
On-board 512KB SRAM and 1MB FLASH are used to store user program and data.
