Hybrid Servo HMC6®

With the HMC solution (Hybrid Motor Cable), HEIDENHAIN has integrated the encoder cable into the power cable. Thus, only a single cable is now needed between the motor and the electrical cabinet. The HMC 6 single-cable solution was specifically designed for the HEIDENHAIN EnDat22 interface. With purely serial data transmission, cable lengths of up to 100 m can be realized. However, with HMC 6 all other encoders equipped with a purely serial RS-485 interface (e.g., SSI) can be connected as well. A wide range of encoders can therefore be used without the need for introducing a new interface. The HMC solution combines the wires for the encoder, motor, and brake into a single cable, which is connected to the motor via a special connector. For connection to the frequency inverter, the cable is split into power connections, brake connections, and an encoder connector.
