Products, consulting and service ESR drive packages consist of servo amplifiers, servo motors, position sensors, gear boxes and brakes. They are supplemented by power supply units (if not already built-in in the amplifier), connectors and cables (ready-assembled on request). All parts of the package are matched and have been tested as combinations. The delivery of the complete drive system from a single source guarantees smooth installation, reliable operation and definite system responsibility on the part of one single supplier. Our service offer includes individual drive system determination....

Fig. 2: Multi-axis servo amplifiers in 19" design; mounting dimensions (mm) The standard mains transformers are designed for MidiDrive servo amplifiers in compact design and 19" design. The required power is calculated according to the load factors of the servo amplifiers. Several servo amplifiers in compact design and several power supplies in 19" design can be connected to one mains transformer if permissible by the load factors of the servo amplifiers. In 19" design, a RFI-filter for compliance with EMC limits in accordance with EN 55011, classes A and B, has to be switched behind the secondary...

tween mains transformer and power supply in case of the devices in 19" design. The operating instructions explain the installation in detail. All MidiDrive servo amplifiers comply with the high immunity requirements in accordance with EN 50082 part 1 and 2. Interfaces of the servo amplifiers All connections can be plugged in at the front of the servo amplifiers in compact and 19" design. This allows a specially easy, clear, and low cost wiring. The trim potentiometers and the LEDs are also located at the front panel. The following connectors are located at the front panel: C motor and operating...

C add-on module C encoder module C function module See the servo amplifier type code on page 16 for an overview of the available modules. Auxiliary units can be used for more complex applications, e. g. C auxiliary unit for axis synchronization (only for 19" design) The following sections describe the modules and the auxiliary unit in detail. Polarity modules P1, P2 The levels of the switched inputs and outputs can be adapted to different controller types using the polarity module. There are two possibilities for the signal polarity of the servo amplifier’s switched inputs and outputs: C switch...

one complete revolution because of inertia. This allows easy positioning solutions. In many cases the holding control loop can render a holding brake unnecessary, which is often used to hold the motor. A brake is only necessary where safety aspects require its use. Function module F2 “Field weakening mode” With the “Field weakening mode” module the attainable speed of the motor can be increased by some 10% beyond the rated speed at reduced torque. The increase of the speed is achieved by a phase shift of the motor current at higher speed. Auxiliary unit for axis synchronization For synchronizing...
