TH270 servo driver

Technical parameters

• DSP (digital signal processor) chip, greatly speeding up the data acquisition and processing speed, the motor running performance is good
• Application of large-scale gate array circuit, the product has a high reliability
• Reduced drive size with the latest power device IPM
• Monitoring function allows display of 24 parameter states, including motor speed, feedback pulse, command pulse, input and output port level and motor current
• RS485 communication function
• With pulse position and analog speed two kinds of input control mode, the system configuration is more flexible
• The magnification of the position command pulse can be set (electronic gear input)
• The magnification of the position output pulse can be set (electronic gear output)
• Position / speed two control modes
• Simple and compact design
• Power range: 400W-3.2KW
• Wide speed ratio, constant torque: The speed ratio is 1: 5000
• High-speed, high-precision: the maximum speed of up to 3000 r / min, rotation positioning accuracy of 1/10000 rpm
