Components of the MidiDrive D servo drives family ז left: BN 6742 servo amplifier of medium power(4 A, U > DC 560 V); MR 4208 motor (3.4 Nm at 3000 r.p.m.), frame size 63; right: servo amplifierBN 6731 (2 A, U > DC 320 V); MR 4608 motor (2.5 Nm at 6000 r.p.m.) > ESR drive packages consist of servo ampli- fiers, servo motors, position sensors, gearboxes and brakes. They are supplemented by power supply units, connectors, cables (ready- assembled on request) and software. All parts of the package are matched and have beentested as combinations. The delivery of thecomplete drive system from a single sourceguarantees smooth installation, reliable opera- tion and definite system responsibility on thepart of one single supplier.Our service offer includes individual drive sys-tem determination. With our long-standingexperience we support you at choosing the right servo drive for your application.

Data sheet 6730.250, V 2.0MidiDrive D3 mains power supply motor metal parts have the best possible electrical contactto each other. 24 V control logic supply voltage protective earth PE (additionally also via a studbolt)According to the application, the Combicon connec-tors can also be used to connect: Power supply unit The power supply unit is built-in. The power sectionis fed directly from the 230 V AC or the 400 V three- phase mains. A control logic supply voltage of 24 V is fed to the control section. The power supply unit contains a RFI-filter and a shunt regulator whose shunt resistor absorbs...

4MidiDrive DData sheet 6730.250, V 2.0 Command mode archived and restored using the SPP Windows PCsoftware.A signal processor controls current and speed andis responsible for the PWM control of the power circuit. With a cycle time of only 62.5 sec the control algorithms ensure high dynamics and con- trol quality. A 16-bit microcontroller controls the position with a cycle time of 1 msec.In the standard configuration, a resolver is used asposition sensor in the motor. If particularly accurate positioning is required, a high-resolution incremen- tal encoder at the motor or an external position...

Data sheet 6730.250, V 2.0MidiDrive D5 part programs part program variablesThe parameters that change dynamically (controland status information, setpoint and actual values) are transmitted cyclically via the Interbus, CAN-open or Profibus-DP process data channel. Up to 18 bytes (Interbus) or 16 bytes (Profibus-DP) are available each for process data input and output. With CANopen 5 PDOs are predefined each forprocess data input and output. The remaining pa-rameters are transmitted via the parameter chan-nels of Interbus (PCP), CANopen (SDO) or Profi- bus-DP. feedforward M functions (set outputs)...
