Commutation and incremental encoder solutions

The OnAxisTM commutation magnetic rotary encoder range is designed for use in motor feedback applications requiring both A, B, Z incremental and U, V, W signals.Robust non-contact OnAxisTM 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 one time zero position programming then removes the need for careful adjustment of the encoder.

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).

● Simple installation and setup ● U, V, W commutation signals

(RS422) ● Up to 16 poles ● Industry standard

incremental outputs (RS422) ● Operating speed to

30,000 rpm ● Non-contact, frictionless

design ● Low inertia

The zero pads can be shorted to set the zero position of the encoder. If the zeroing is successful, the LED flashes red.

zero pads

The output angle position data can be zeroed at any angle with resolution of 0.0879°. The relative output position is the difference between absolute position and data in the zero register. The value in the zero register can be changed by writing a desired value with the TWI interface or with using a “Zero” input pin. With low to high transition of a signal on “Zero” pin the current absolute value is stored into the zero register. When zeroing the relative position, the chip must not be in power-save mode as the EEPROM is not accessible in this state.

1. Install the magnetic actuatorUse glue to fix the magnetic actuator to the shaft (recommended LOCTITE 648). Actuator should protrodue by 7 mm.

2. Install the flange with the encoder module on the mounting surfaceScrew the flange to the mounting surface using 2 screws (not provided).

3. Set the zero position of the encoder (see below for details) 4. Cover the encoder with the metal cover

Place the metal cover over the encoder and gently press it in position. Be sure to align the opening with the connector.5. Plug in the mating connector
