2.1 servo driver
2.1.1 General
JAND_P28/DB44 series universal servo driver is a high-performance AC servo unit developed by JMC. This
series of servo driver adopts advanced DSP chip for motor control, large-scale programmable gate array (FPGA) and
IPM power module, which has the characteristics of small size, high integration, stable performance and reliable
protection. It has rich digital and analog I/O interfaces, can be used with a variety of host computer devices, and
supports MODBUS communication protocol to facilitate networking. Through the optimized PID control algorithm,
the position, speed, torque accuracy of the full digital control, with high precision, fast response and other
advantages. Supports 17-bit and 23-bit high-precision absolute encoder motors to meet different customer
performance requirements. Widely used in CNC machine tools, printing and packaging machinery, textile
machinery, robots, automated production lines and other automation fields.
2.1.2 Main Features
1. Using DSP+FPGA dual-chip platform and optimized current loop design, the driver has the characteristics of
high dynamic response, very short setting time, stable operation and small vibration when stopping.
2. With automatic gain adjustment module, users can choose the rigidity level according to their needs.
3. Built-in FIR filter and multi-notch filter can automatically identify and suppress mechanical vibration.
4. Built-in disturbance torque observer makes the actuator have strong anti-external disturbance ability.
5. With a variety of control modes to choose from, position control, speed control, torque control, can switch
various control modes.
6. The position pulse input frequency is up to 1MHz, and supports multiple position command modes such as
pulse + direction, orthogonal pulse, and double pulse.
7. With RS485 interface, support MODBUS communication, with multi-turn absolute encoder with memory
function, it can be flexibly applied to manipulator and other industries.
8. There are programmable 5-way INPUT and 4-way OUTPUT ports, users can customize the input and output
through parameter settings, and the application is flexible.
