1 Overview
1.1 Features
WISE (Chinese name as "维智", “维”is one character in Chinese company name “维宏”, and “智”is for
intelligence and wisdom. Besides, pronunciation of “维智”sounds like that of English word “wise”) series
servo driver is another expansion in motion control industry chain of Weihong Company. It boasts such
functions as real-time auto-gain tuning, adaptive mechanical resonance suppression, friction torque
compensation, external disturbance observer, gain switching and time register, to name but a few.
Thanks to its precise positioning, quick response and ease of use, it has been proven to be an excellent
and reliable solution provider when it is used together with Weihong CNC system. Chain-like product
combination can effectively reduce components number and type for machine tool builders and facilitate
daily maintenance for machines.
1.1.1 Outstanding Positioning Precision and Low-speed
Smoothness
It supports encoder with high resolution, reducing variation of torque, improving positioning precision of
motor and enhancing smoothness of low-speed motion.
Fig. 1-1 When there is stiffness difference, WISE servo driver can keep motor un-oscillated via gain switching function.
1.1.2 Ease of Use
It features auto calculation of inertia ratio, real-time auto-gain tuning and auto suppression to mechanical
resonance.

1.1.3 Powerful Support Software
WISE servo driver can be used with the setup support software, “iMotion”, which is user-friendly in HMI,
and features functions such as real-time I/O monitoring and auto capture and analysis of waves.
Fig. 1-3 Example of iMotion
With the “iMotion”, you can execute the followings.
Parameters Management
Editing, transmission, receipt, import, export and initialization of parameters can be realized, which is
very convenient for operators.
Real-time Monitoring
Monitoring of I/O, existing alarms and history alarms, as well as system running status.

Real-time/Triggered Sampling
Main data waves in running will be captured with Real-time/Triggered Sampling function, for debugging
and analysis.
Debugging
Rapidly adjust the servo driver stiffness, automatic calculation of inertia ratio.
Mechanical Analysis
Through FFT algorithm, quickly analyze and find the mechanical resonance point, and automatically
setup notch filter to suppress vibration.
Trial Run
With versatile Trial Run interfaces, various application situations in real practices can be simulated.
