Servo Motors Technology − short and to the point
Servo motors are motors with or without an integrated motor controller for industrial applications. They are typically used as slaves in a master-slave architecture and receive motion commands from the higher-level master system (e.g., PLC), usually via a fieldbus connection.

IDX Servo Motors
Alternative version without fieldbus (I/O version) Commands are given via the inputs and outputs. In this case, only current and speed control are supported (no position control). Optional brake The holding brake blocks the motor when disconnected from power. The brake is controlled by the integrated controller. – The drive length increases slightly – The holding brake is not suitable for deceleration – The brake influences the temperature range and the minimum permissible supply voltage – The electrical properties, performance data, dimensional drawings, and CAD data of the brake with drive are available online. Cable Only minimal work is needed for cabling the IDX drive, as only the power supply, command cabling, and, if necessary, the I/Os have to be connected. In the online shop, maxon offers a selection of suitable cables.
Drive selection maxon IDX drives are integrated systems that are not viewed and configured as separate motor-controller combinations. The supply current and supply voltage are not the currents and voltages that are present at the motor. For this reason, the data sheet does not specify motor charac- teristics, such as torque constant or speed constant. For specification in an application, the nominal torque, the maximum torque (short-term), the nominal speed, as well as the maximum drive speed have to be ref- erenced for the given supply voltage. The operating range diagrams can be useful for this. Detailed documentation can be download- ed at www.maxongroup.com.
The maxon IDX drives consist of a brush- less DC motor (EC-i technology), a mag- netic absolute encoder, and optionally an EPOS4 positioning controller. – IP65 protection; only the output shaft needs to be sealed by the customer. – Integrated temperature sensors on the winding and in the controller are evaluated directly in the drive and enable optimal utilization of the operating range. EPOS4 positioning controller The integrated EPOS4 enables different operating modes: Positioning, speed or current control. The drive can be commanded via EtherCAT or CANopen. The IDX drive is equipped with configurable digital and analog inputs and outputs. These are matched optimal- ly to the various functions and operating modes of the CiA-402 device profile. − Easy commissioning due to preconfig- ured motor, encoder, and brake param- eters, as well as auto-tuning function – EPOS Studio: Intuitive software for commissioning – Libraries for lean integration into a wide variety of master systems – Documentation and software available free of charge
