IC693ACC323B Gas turbine module

With the introduction of EN 62061 and EN ISO 13849–1 as successor to the EN 945–1 standard, several things have changed regarding the assessment of suitable safety technology. Not only is the structure of a safety–related circuit taken into consideration, as was previously the case according to EN 954–1, but beyond this, the performance of the safety technology is also assessed along with the reliability; and if necessary, the software and many other related issues.The Safe Torque Off (STO) function is a safety function to avoid unexpected starting. This function prevents the unexpected starting of a motor, connected to the drive control unit, from standstill. When the Safe Torque Off function is activated, the motor shaft cannot generate a torque.

High–voltage test in the system

 It is permissible to perform a high–voltage test on SIMODRIVE 611 drive converters. The components are designed/dimensioned in compliance with DIN EN 50178. The following secondary conditions/limitations must be carefully observed when the system is subject to a high–voltage test: 1. Power–down the unit. 2. Withdraw the overvoltage module in order to prevent the voltage limiting responding. 3. Disconnect the line filter so that the test voltage does not dip. 4. Connect M600 to PE through resistor 100 kΩ (the grounding clip in the NE modules is open). In the factory, the units are subject to a high–voltage test at 2.25 kVDC phase–PE. The NE modules are shipped with the grounding clip open. 5. The maximum permissible voltage for a high–voltage system test is 1.8 kVDC phase–PE. If these points are not carefully observed, then the modules can be damaged (preliminary damage)

This safety function should only be activated

 after the drive has come to a standstill, otherwise it loses its braking capability. The standstill of the drive as well as the activation of the Safe Torque Off function must be realized and secured using an external machine control. If the drive is at a standstill and the Safe Torque Off function is active, additional brakes may be required for dangers due to the fact that the drive shaft is subject to an external torque. For SIMODRIVE 611, the Safe Torque Off function is a ”Device to shut down and avoid unexpected starting” according to EN 60204–1 Section 5.4. This behavior corresponds to stop Category 0, according to EN 60204–1:2006. There is no electrical isolation from the line supply with the Safe Torque Off function. As a consequence, this function does not represent a protective device against electric shock. Safety function SS1 – safe stop (time controlled) Initiates that the motor decelerates, and after an application–specific delay, initiates the STO function.
