Data sheet UVWD01_01 Issue 1,26th June 2017 RLSCommutation and incremental magnetic encoder solutions Commutation and incremental encoders for motor applications OnAxis™ commutation magnetic rotary encoder range is designed for use in motor feedback applications requiring both A, B, Z incremental and U, V, W commutation signals. Robust non-contact OnAxis sensor technology provides ultimate long term reliability and with simple installation costs of ownership are minimal. Installation is simplified with a range of magnetic actuators and mounting options for the encoder. A simple zero position programming then removes the need for careful alignment of the encoder to starting position of the rotor. Resolutions are available from 64 to 2,048 pulses per revolution (256 to 8,192 counts per revolution with *4 evaluation). U,V,W commutation signals are simultaneously output with 1 to 8 pole pairs (2 to 16 poles). Commutation encoders are available in different design variants and sizes, from 20 mm diameter encoder module RMB20 to 44 mm diameter encoder module on a metal flange RMF44 or as RMC22 and RMC35 on a metal flange with a removable metal cap to allow easy installation and zeroing. The functionality of all the above mentioned encoders is based on the AM4096 magnetic encoder IC which provides reliable operation in tough environments. More on the funcitonalities of AM4096 magnetic encoder IC can be found in AM4096 data sheet. • Robust non-contact OnAxis encoders • Resolutions from 256 to 8192 counts per revolution • U, V, W commutation signals • Encoder module sizes from 20 mm diameter to 44 mm diameter • Operations in tough environments • CE compliant, including RoHS see Declaration of conformity A REIMISHAW.B associate company

WARNING! ESD protection Encoder modules are ESD sensitive - handle with care. Do not touch electronic circuit or sensor area without proper ESD protection or outside of ESD controlled environment.

Incremental outputs There are three signals for the incremental output: A, B and Z. Signals A and B are quadrature signals, shifted by 90°, and signal Z is a reference mark. The reference mark signal is produced once per revolution. The width of the Z pulse is 1/4 of the quadrature signal period and it is synchronized with the A and B signals. The position of the reference mark is at zero. The chart below shows the timing diagram of A, B and Z signals with clockwise (CW) rotation of the magnet and positive counting direction. B leads A for CW rotation. Timing diagram - Incremental Complementary...
