MOTOROLA MVME147-024A output card

Connect up the unit according to the wiring diagram in Chapter IV.4.5. The unit is supplied from the auxiliary voltage (terminals +25V, XGND) which is also available in the servo amplifier. Internally, this is electrically connected to the analog ground (AGND). There is an internal fuse for the positive pole. Both poles are decoupled via HF chokes. If you want to use the pulse encoder signals in the control system, then the driver circuitry on the option board must be provided with a 5V supply (see Chapter IV.4.5). The analog speed controller is normalized for 1024 pulses / turn. You can use the soldered link LB1 to set the speed controller to a final limit speed of 3000 rev/min (LB1 open) or 6000 rev/min (LB1 closed).

Important notes

Close all the hardware limit switches in the higher-level control and combine the signals in an AND function. Join the servo amplifier inputs PSTOP and NSTOP together (see Chapter IV.4.5). Connect the output of the AND function to the joined inputs PSTOP/NSTOP. In order to be able to amplify away from an activated limit switch, the controller must produce a speed setpoint value with the correct polarity sign for traversing away from the activated limit switch and then 24V must be applied to the bridged limit switch. In the event of an overload of the servo amplifier, the effective current limit within the servo drive (I2 t) remains active.
