Parker EME Compax3 device description192-120114 N5 C3I22T11 June 2008 813.10.4. Application example for ”safe standstill”In this chapter you can read about:Safe standstill with bus option ............................................................................................81The application example described here corresponds to Stop Category 1 as defi-ned by EN60204-1.A Stop Category 0 in accordance with EN 60204-1 can be implemented, for exam-ple by setting the delay time on the Emergency power-off switch to 0. The Com-pax3 drive will then be turned off immediately in 2 channels and will not be able togenerate any more torque. Please take into consideration that the motor will notbrake and a coasting down of the motor may result in hazards. If this is the case, a”Safe Standstill” in the stop category 0 is not permitted.3.10.4.1 Safe standstill with bus optionIn this chapter you can read about:Note: .................................................................................................................................. 81Layout: ............................................................................................................................... 81Circuit example .................................................................................................................. 82Description......................................................................................................................... 85Note:If the "safe standstill" function of Compax3 is required or used for amachine or system, the errors: "Motor_Stalled" and "Tracking"is not to be switched off (see page 152, see page 137).Layout: 2 Compax3 devices (the circuit example is also valid for one or multiple devices,if it is adapted accordingly) 1 Emergency Power-off module (BH5928.47 manufactured by Dold)With adjustable delayed deactivation of the Compax3 enable input.The time must be set so that all axes are at a standstill before the Compax3 con-trollers are deactivated. 1 safety door monitor (BD5985N made by Dold)Note: With safety door monitor BD5985N, the safety door must be opened andclosed again every time after turning on the 24 V power supply so that the Emer-gency power-off module can be acknowledged and reset.
