Set After Power on:
Find P-098 and change it to 1
Find the E-SEF, press and hold the confirmation key until it shows DONE. then the parameters has been saved successfully. After all parameters are set, power off and restart.
Common parameters:
P-036 is changed to 1 (reverse direction) 0 (positive direction) motor direction conversion parameter. The default is 1 reverse direction
P-029 (electronic gear ratio numerator) is 1 by default, the higher the value, the faster the speed
(The above parameters are general setting parameters. If you need to modify other parameters, please refer to the manual or contact the technical/sales personnel)
The following parameters are rigid adjustment parameters. No adjustment is needed if the equipment is OK
P-005 (Speed ring rigidity)
P-009 (Position ring rigidity)
P-006 (generally, the maximum setting is about 100)
P-019 (generally, the maximum setting is about 300)
The specific adjustment of rigid parameters depends on the transmission structure and load of the equipment. Contact the after-sales service personnel for specific questions.

1. [Absolute accuracy, derived from core encoder technology]
17 bit magnetic absolute encoder (131072 pulses/turn): This is the key to achieving ultra-fine engraving. The extremely high resolution means that every small rotation of the motor is precisely controlled, resulting in a silky smooth surface treatment effect and sharp detail expression.
Power off without returning to zero, ready to use upon startup: the greatest convenience upgrade! After the device is powered off or restarted, the system will automatically remember the current location without executing the origin search program. This not only saves a lot of time, but also completely avoids the collision risk that may occur during the zeroing process, protecting your tools and workpieces.
2. [Surge power, easy to handle heavy cutting]
Wide power range (400W/600W/750W/1KW): Whether your device is a small desktop engraving machine or a large CNC milling machine, you can find a matching power solution. The 1KW high-power model can easily gnaw on hard materials such as steel.
220V industrial voltage+20A high current driver: provides continuous and stable strong power output. Even at low speeds, it can output rated torque, ensuring that the speed does not decrease and the tool does not get stuck during heavy load cutting, doubling the machining efficiency.
3. [Closed loop operation, 100% prevention of step loss]
A true servo closed-loop system: fundamentally different from an open-loop stepper motor. The system monitors the motor status in real-time and compares it with commands. In case of unexpected resistance, it will instantly increase the torque output instead of "losing step". This means that the processing results are 100% consistent with the design drawings, eliminating the worry of waste.
4. [Ready to use out of the box, perfect compatibility]
Carefully matched motor driver set: We have completed the complex matching and parameter preset work for you. After receiving the product, you only need simple mechanical installation and wiring to quickly integrate it into your CNC system (compatible with mainstream control software such as Mach3, Mach4, LinuxCNC, etc.), greatly reducing the debugging threshold and time cost.
