LXM28 servo amplifier from the Lexium 28 servo drive range. These servo drives offer predefined combinations of amplifiers and motors to meet motion control applications, optimize performance and offer very simple integration and commissioning in your system. They include numerous functions such as auto-tuning, position, speed and torque control as well as position sequence mode. Their compact dimensions enable easy installation even in tight control cabinets. The supply voltage of this servo controller is 200-240 VAC from three-phase networks. A nominal power of 100 W is provided at the output. The interfaces available are: PTI/PTO, analog 2 inputs (+-10 V) and 2 outputs (+- 8 V), digitally configurable 8 inputs and 6 outputs. The fieldbus connection and motion control from a PLCopen library are carried out via CANopen or CANmotion. The STO safety function is implemented up to PL d/SIL2. An internal braking resistor is available to absorb the braking energy. An external resistor can also be connected for frequent braking operations. An output enables the holding brake to be controlled. The associated BCH2 servo motors from the Lexium 28 series must be used for operation. Thanks to the Green Premium eco-label, you can obtain detailed information on material content, environmental impact and circular economy that supports your sustainability goals.
