Features: The HES / HEM encoders are designed for installation in our HeiMotion series. They are connected to the connectors on the motor side. The pin assignment can be found in the separate catalogs for the motor series. The encoders in the HES/HEM series detect a magnetic field which is generated by a magnet at the end of the shaft Depending on the variant, the following interfaces are available: • SSI, BiSS C (BP3) with 4096 values per revolution • Incremental signals ABZ with 256 to 2048 PPR3 • Commutation signals UVW suitable for the motor • sin/cos output with 1 period per revolution and 1 Vpp Absolute encoders singleturn Absolute encoders multiturn, battery backed Incremental and/or commutation signals sin/cos 1 period / revolution differential, 1.0 Vpp (only with braid wire X2) SSI differential, gray coded, 12 bit ST BiSS differential, binary coded, SSI single ended, gray coded, 12 bit ST (only with connector X1) external battery required with built-in battery €)HekUve A Company of AliiedMotion
