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....

Single-axis servo amplifiers, compact design For single-axis applications a compact enclosure with built-in power supply and integrated RFI-filter is available. The 19" servo amplifier plug-in module is fitted into this compact enclosure. The TrioDrive servo amplifier in compact design formed this way can be mounted onto the mounting plate of a control cabinet or into the machine rack. pact amplifier contains the shunt regulator with a shunt resistor which takes up the energy fed back from the motor during braking. Alternatively, an external shunt resistor can be connected. Of the variety of...

transformer. For connection to other mains voltages special transformers are available. For low power single-phase mains connection is possible. The standard mains transformers are designed for TrioDrive servo amplifiers in compact design and 19" design. The required power is calculated according to the load factors of the servo amplifiers. Only one servo amplifier in compact design or only one 19" power supply may be connected to one mains transformer winding. 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...

Customer module The set-up elements and the components for the application-specific controller settings are located on the plug-in customer module. When an amplifier is replaced, the customer module can be transferred to the new amplifier. By this the controller settings are kept and readjustment is not necessary (except offset). Monitoring and protective circuits Built-in monitoring and protective circuits protect servo amplifier and motor against damage even in extreme situations and switch off the drive in case of a fault. The circuits monitor: C amplifier output for short circuit and earth...

(incremental encoder pulses per revolution) can be selected: C 128, 256, 512, 1024, C 50, 100, 200, 250, 500, 1000, C 60, 90, 180, 360, 720, 900 Other pulse numbers are also available on request. The pulses are generated by 5 volts line drivers (RS 422 compatible; G1 and G3 options). A version with 24 volts pulse output is also available (G2 and G4 options). With the G3 and G4 options the index pulse can be shifted in 256 steps within one motor revolution. If the control circuit of the TrioDrive servo amplifier is fed by an external 24 V power supply (E1 option, details see section “Mains connection...
