Page 7: Safety Symbols
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
…among others. Up to three optional boards can be connected, maximum two of the same type. This manual focuses on the optional encoder board. The encoder board allows the SD750 to be connected to an encoder to measure the speed of the motor it controls. This card has two channels for the connection of this encoder, which will be essential to have for closed-loop controls. -
Page 10: Encoder Board Specifications
SD750 POWER ELECTRONICS Encoder board specifications • Device type: Encoder. • Outputs for powering each encoder, programmable from 5VDC to 24VDC. • Optical insulation between the encoder and the control board. • Inputs for Channel A, /A, Channel B, /B and Channel Z, /Z (zero pass detection). -
Page 11: Connection To The Drive
The encoder 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 integrating an encoder through its connection to the expansion card. -
Page 12: Connectors Description And Led Indicators
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 13 POWER ELECTRONICS SD750 TERMINAL DESCRIPTION Input voltage for Motor encoder +5VDC +24V Alimentación del encoder +24VDC Common terminal for input voltage of Motor encoder Channel Z (inverse polarity).
