  • Page 90 SD750 POWER ELECTRONICS It is recommended to use double shielded twisted-pair cable for 24Vdc power supply and safety channels. The shield must be grounded as shown in the examples. When a PNP or NPN input is configured, the rest of digital inputs will have to be the same. This means, PNP and NPN inputs cannot coexist.

Ground cable screening must be connected only in one end. For further information about parameter configuration, consult the Software and Programming Manual.

  • Page 93: Sto - Safe Torque Off

    STO function is applied, the motor will freely stop by its own inertia. The STO function integrated as standard in the SD750 permits to achieve safety level SIL3 (PLe) for the safe stop function. SIL3 requires the use of an emergency pushbutton The maximum reaction time of STO function is less than 50ms.
  • Page 94 SD750 POWER ELECTRONICS Example 1- Emergency stop push button CAUTION According to EN 60204-1 automatic restart is not allowed after an emergency stop. For this reason, the machine control must prevent an automatic start after an emergency stop. For SIL 3 applications the safety function has to be tested regularly (approximately once per month) in order to detect certain failures.

This function is used to prevent an unexpected restart when a maintenance task is being carried out in a risk area. In this case, the relay’s safety inputs will be connected to a safety interlock switch placed in the door.

    Power Electronics provides a solution for driving ATEX motors such as “Ex nA”, “Ex d” and “Ex p” under the ATEX zone areas illustrated below. For different motor and ATEX zone combinations, consult Power Electronics.
  • Page 97 SD750 As shown in the figure above, the SD750 drive and the ATEX relay must be installed in a safe zone, outside the ATEX zone. This solution is valid for motors with "Ex d" or "Ex p" protection installed in zones 1 and 2, or motors with "EX nA"...

  • Page 98: Modbus Communication

    The purpose of the Serial Communication Bus of the SD750 drive is to integrate the drive itself into a network compatible with the Modbus communications protocol. This is possible using the physical communications ports RS485, Ethernet or USB port.

    Note: For the installation of the driver in the Host of the SD750 USB, it is only necessary to indicate the driver at the time of the installation. The USB device will be detected by the operating systems XP or later versions. In case of operating systems before W98 / Me, execute a search of new Hardware in the device administrator and complete the installation by indicating the drivers when the computer requires them.
