Digital AC Servo Drives with Direct Mains Connection 3 × 400 V AC C Motors up to 17 Nm / 4.2 kW Integrated Positioning Control (Option) Components of the MidiDrive D servo drives family: BN 6742 servo amplifier of medium power (4 A), MR 4208 motor (3.4 Nm at 3000 r.p.m.), MR 4608 motor (3.5 Nm at 6000 r.p.m.) Products, Consultation, Service ESR drive packages consist of servo amplifiers, optionally with fieldbus interface and positioning control, and servo motors with or without gearboxes, completely with position sensors and, if required, brakes. They are supplemented by software and accessories. All parts of the packages are matching and have been tested as combinations. This delivery from a single source guarantees trouble-free commissioning, reliable operation, and a definite system responsibility on the part of only one supplier. Our services include an individual drive system configuration. With many years of experience, we will be pleased to assist you at choosing the appropriate servo drive for your application.

tions with particularly high requirements to the positioning accuracy, a high-resolution incremental encoder, a Sincos (Hiperface) encoder, or an EnDat encoder can be installed, optionally. For protection against overheating, the motors are equipped with a temperature sensor which is evaluated in the servo amplifier. The connection of motor and position sensor is done via connectors (higher powers via terminal box). Detailed information on the motors can be found in separate data sheets and in the internet on www.esr-pollmeier.de. Motor accessories C Brakes – Permanent magnet brake, designed...

SUB-D connectors are provided at the front panel for the connection of: C motor position sensor (resolver as standard, optionally high-resolution incremental encoder, Sincos (Hiperface) encoder, or EnDat encoder) C input or output encoder signals (option) Input encoder signals is provided for axis coupling (synchronization, electronic gearing, flying shear), external position sensor, or pilot frequency; output encoder signals for incremental encoder emulation C COM1 (RS 232C, optionally RS 485) for connecting a personal computer C analog signals (2 setpoint inputs, 2 monitoring outputs) Connectors...

shear) C a communication interface – serial interface COM1 (RS 232C, optionally RS 485), or – fieldbus interface (optional) The behavior of the drive in the different axis operating modes can be adapted to the application via machine data. Thus, e. g. acceleration and deceleration ramps can be set independent of each other (with trapezoidal or sin²(t) ramps, if required); any gear ratio with a high value range can be selected for electronic gearing. Program mode The program mode is available as an option. For that, a positioning control is integrated into the device running a part program which...

Serial interface All parameters of the drive can be transmitted via the serial interface. For that, the DRIVECOM profile 22 parameters are used there, as well. Therefore, users working only with the serial interface at the beginning can make use of the knowledge acquired there in case of a future application of a fieldbus. Sercos interface This interface is in preparation. If required, please contact ESR. Commissioning and Software The MidiDrive D servo amplifier is delivered ready for operation. For commissioning, a PC can be connected via serial interface COM1 or the optional fieldbus interface....

Drive Packages (Selection), Important Technical Specifications, and Order Numbers In addition to the motors listed below, a lot of other motors are available. Detailed information can be found in separate data sheets and in the internet on www.esr-pollmeier.de. Flange Dimension (mm) Order Number Motor Shaft Order Power Number (kW) Amplifier The rated torques refer to the stated speed. At lower speeds, the torques are higher. We recommend to choose the best combination for your application together with us. We will be pleased to calculate and configure the drive system in cooperation with the...
