Data sheet RMCD01_0 Issue, th pril 015 RMC commutation and incremental encoder solution / complementary sinusoidal outputs The RMCUx is designed for use in motor feedback applications requiring both, B, Z incremental and U, V, W commutation signals. The RMCBC provides analogue complementary sinusoidal outputs. Robust non-contact Onxis TM 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. simple one time zero position programming then removes the need for careful adjustment of the encoder. Resolutions are available from 56 to 1,0 pulses per revolution (1,0 to,096 counts per revolution with evaluation). U,V,W commutation signals are simultaneously output with 1 to 8 pole pairs ( to 16 poles). Incremental resolution up to,096 cpr Simple installation and setup U, V, W commutation signals with up to 16 poles (± m output drive) Industry standard incremental outputs (RS) Operating speed to 30,000 rpm Compact - mm diameter body Non-contact, frictionless design Low inertia

Install the magnetic actuator Use glue to fix the magnetic actuator to the shaft (recommended LOCTITE 68 or LOCTITE 701). ctuator should protrodue by 7 mm.. Install the flange with the encoder module on the mounting surface Screw the flange to the mounting surface using screws (not provided). 3. Turn the power on Plug in the mating connector and turn on the power.. Zero the UVW signals Move the motor to the required zero UVW position. Short together the two zeroing pads. metal cover screws metal flange magnetic actuator mounting surface zeroing pads 5. 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. Zero function ll the outputs can be zeroed at any angle. The first rising edge in the U signal will be reset at this point of zeroing as well as the position of reference impulse for incremental outputs.
