    POWER ELECTRONICS SD750 SAFETY SYMBOLS Always follow safety instructions to prevent accidents and potential hazards from occurring. In this manual, safety messages are classified as follows: Identifies potentially hazardous situations where dangerous voltage may be present, which if not avoided, could result in minor personal injury, serious injury or death.

  • Page 8: Safety Instructions

    For maintenance operations, follow the instructions from the Maintenance Manual. Power Electronics accepts no responsibility for any damages resulting from incorrect use of equipment. CAUTION Read carefully the Hardware and Installation Manual, the Maintenance Manual and all documentation related to the drive to guarantee its safe use and avoid the risk of personal injuries and damages to the equipment.

  • Page 9: Introduction

    This manual focuses on the optional analogue input/output (I/O) expansion board. This board allows to increase the number of analog inputs and outputs compared to those of the SD750. This board allows the drive to increase its inputs and outputs as follows: •...

  • Page 10: Analog I/O Expansion Board Specifications

    When we state that the system operates correctly, it means that the communication between the expansion board, the network controller and the central SD750 microcontroller is correct. This does not mean, however, that the communication with the PLC is correct.

  • Page 11: Connection To The Drive

    The analog expansion board can be connected directly, through the connector on its back side, to any of the three expansion connectors of the SD750 drive central control board. Once connected, it allows the drive to be equipped with more analog input and output options and to display new parameter groups. Up to two cards of this type can be connected to each drive.

  • Page 12: Connectors Description

    It has four analog input connectors, two for each analog input (AI1, AI1+, AI2, AI2+). There are four output connectors, two for each analog output (A01, A01+, A02, A02+). On the back side, there is a sixteen-pin ID connector to connect to the SD750 central board. CONNECTION TO THE DRIVE...

  • Page 13: Connections Schema

    POWER ELECTRONICS SD750 Connections Schema The following figure shows a detailed distribution of the components of the optional input/output card. In the current printing the analog inputs 4 and 5 appear as AI1, AI2 and the analog outputs 3 and 4 appear as A01, AO2 as shown in the figure above.

  • Page 14: Commissioning

    Check that the communication with the SD750 is correct (by displaying group G23.2). See that the analog expansion board (A/B) status is activated (G23.2.5). Reference is made to a card A if only one card is connected and B if there is a second card.

  • Page 19 POWER ELECTRONICS SD750 Set on Screen Range Function m3/s m3/m Allows choosing different measure units for the analogue input 6 depending on the function of the m3/h sensor to be used. Changing this parameter implies that the minimum and maximum values of the sensor range will be affected by the corresponding conversion.
  • Page 20 SD750 POWER ELECTRONICS Set on Screen Range Function Allows adjusting a filtering to the analogue input 6 signal. By adjusting the value of this time constant, it is possible to eliminate possible instabilities in the signal caused by noise, wiring faults, G4.7.16 AI6 stabilizer...
  • Page 21 Note: The application of a low pass filter to any analogue signal produces a delay of approximately the value of the configured time constant. NOTICE Each input can be configured with multiple options, refer to the SD750 Drive Software & Programming Manual for more information on the functions of each input. COMMISSIONING...
  • Page 22 SD750 POWER ELECTRONICS Analog Outputs Sub-groups G8.2 to G8.7 of the SD750 drive are used to configure the analog outputs. When an expansion card is connected to the drive, new parameter subgroups for analog outputs are enabled in group G8.
