· Powerful internal position mode can plan multi-path continuous operation to achieve rich motion control functions; support up to 32 sets of data planning, each set of data can set the number of pulses, angles, the speed of the internal position mode, acceleration, deceleration, and emergency deceleration according to requirements.

· Automatically test the mechanical characteristics of the load inertia, set the optimal gain, and shorten the system commissioning time.

· Analysis of mechanical resonance frequency, equipped with two sets of notch filters, which can adjust the frequency (50 ~ 5000Hz) and notch depth, effectively overcome low frequency resonance and the vibration of the mechanical end, and can set the vibration frequency (1 ~ 100Hz) and vibration damping.

· The friction torque compensation function can reduce the effect of static friction during mechanical commutation and improve the command following performance of low speed operation.

· Supported by commissioning software which can perform mechanical characteristic analysis, parameter setting, monitoring and other functions. The operation is intuitive and simple.
