Description
Description
- Unipolator is a multi-function pulse modulator incorporating signal distribution, interpolation, decimation and digital filtering.
- JTED-100 series generates high precision digital encoder/ trigger signals interpolated up to 1000 times to selectable 3 output channels for one input signal from the analog encoder and compensates position errors of each signal for high precision
position control
- JTED-500 series generates 2 selectable high precision encoder/ trigger signals whose position error is compensated for one digital input
Features
Simple to integrate with the existing devices
- Compact size : Easy to install on the existing devices due to small space requirement
- Easy integration : Simple to install between the encoder and controller
- Diverse pulse type conversion (A/B, Pulse/ Dir, CW/ CCW) : compatible with diverse devices
Free from synchronization of multiple encoders
- Generates up to 3 synchronized signals for 1 analog/ digital encoder signal
- High space efficiency and signal synchronization by use of a single encoder
Interpolation of analog encoder
- Can realize high resolution up to 20nm(x1000) using 20nm pitch standard encoder scale
Generation of real-time high precision signals based on patented algorithms
- Working on any user specified input/ output frequency ratio (5/3, 117/23, etc.)
- Signal compensation : puls with encoder position error compensated in real time.
Easy parameter setting/ management by use of GUI
Functions
- Signal distribution : Generates up to 3 synchronized digital encoder output signals in diverse form (A/B, Pulse/ Dir,CW/ CCW) from 1 analog/ digital input encoder signal
- Signal interpolation : Generates encoder pulse interpolated up to 1000 times
- Signal decimation : Generates high precision trigger signals with arbitrary input/ output ratio based on patented algorithm
- Signal compensation : Real time position error compensation based on patented algorithm
- Signal modulation : Processes diverse form of signals and mitigates vibration via digital pulse modulation
