    Safety Instructions Only a qualified electrician who has appropriate knowledge on functional/machine/process safety is allowed to install, start up and maintain the safety circuit. WARNING! This safety function does not disconnect the voltage of the main and auxiliary circuits from the drive. You must not work on the electrical parts of the drive or the motor before you have also disconnected the drive system from the electric supply and ensured by measuring that there is no dangerous voltage present.
  • Page 5: Introduction To The Manual

    Introduction to the manual Contents of this chapter This chapter describes the manual in short and gives some general information for the reader. The chapter also contains a quick reference for implementing a safety system. Applicability The manual applies only to DCS880-A cabinet drives and to DCS800-A cabinet drives with plus code +S880 (exchange of DCS800 with DCS880 drives modules) which have the option: Emergency stop, stop category 1 with STO, with safety relays (option +Q964).

    +Q964 Detailed timing chart +Q964 Fault reaction function Definition: A safety function requires a ‘fault reaction function’ that attempts to initiate a safe state if the safety function's diagnostics detect a fault within the hardware/software that performs the safety function. The fault reaction function of the emergency stop safety relay [A61] trips if it detects a failure (short circuit between signals, open circuits, redundancy fault when the emergency stop button is pushed) in the safety circuit.

    Parameter settings This table lists the drive parameters settings for the +Q964 option. For more information, see the firmware manual. Name Value Description 10.24 RO1 source P.31.98b11 Selects a drive signal to be connected to relay output RO1. In this case, the RO1 is energized if the Drive is in STO state and no STO related fault is active.
  • Page 13: Hardware Settings

    Hardware settings Set the time delay of the emergency stop safety relay [A61] according to the application needs on the safety relay. Instructions: 1. Push and hold the Select button when "CUS" appears on the display to start with the custom settings.
  • Page 14: Wiring

    Wiring At least one emergency stop button and one reset button need to be installed at a suitable place near the machine. There must be double contacts in the emergency stop button and double wiring (two- channel connection) between the button and the emergency stop safety relay [A61]. The safety relay detects cross faults and faults across one contact from the emergency stop button.
  • Page 15: Q964 Start-Up And Acceptance Test

    +Q964 Start-up and acceptance test You need the Drive composer PC tool or a control panel to perform the start-up and acceptance test. Initial status: Make sure that the drive is ready for use, that is, you have done the tasks of the drive start-up procedure.
  • Page 16: Use Of The Safety Function

    Use of the safety function Activating 6. Push the emergency stop button [S61]. The emergency stop activates and the button locks in “ON” (open) position. Resetting 1. Turn the emergency stop button [S61] until it releases. 2. Push the emergency stop reset button [S62]. The emergency stop indication lamp [P62] goes out, the emergency stop deactivates.
