ABX-EIPS-PRTS 1) Use 100 years to calculate a safety loop. 2) According to EN ISO 13849-1 table E.1 • The following temperature profile is used in safety value calculations: • 670 on/off cycles per year with ∆T = 71.66 °C • 1340 on/off cycles per year with ∆T = 61.66 °C • 30 on/off cycles per year with ∆T = 10.0 °C • 32 °C board temperature at 2.0% of time • 60 °C board temperature at 1.5% of time • 85 °C board temperature at 2.3% of time • The STO is a type A safety component as defined in IEC 61508-2. • Relevant failure modes: • The STO trips spuriously (safe failure) • The STO does not activate when requested A fault exclusion on the failure mode “short circuit on printed circuit board” has been made (EN 13849-2, table D.5). The analysis is based on an assumption that one failure occurs at one time. No accumulated failures have been analyzed. • STO reaction time (shortest detectable break): 1 ms • STO response time: 5 ms (typical), 10 ms (maximum) • Fault detection time: Channels in different states for longer than 200 ms • Fault reaction time: Fault detection time +10 ms • STO fault indication (parameter 31.22) delay: 90 3 3 02A6-4 e 80 2569 >90 3 3 03A3-4 e 80 2568 >90 3 3 04A0-4 e 80 2568 >90 3 3 05A6-4 e 80 2568 >90 3 3 07A2-4 e 80 2568 >90 3 3 09A4-4 e 80 2568 >90 3 3 12A6-4 e 80 2568 >90 3 3 17A0-4 e 80 2569 >90 3 3 25A0-4 e 80 2569 >90 3 3 3AXD10000299801.xls Type ACS380- 04xx IEC 61508 and IEC/EN 61800-5-2 IEC/EN 62061 IEC61511 PL rating CCF (%) MTTFd 1 (a) DC2 (%) SILCL SIL 132 Safe torque off function Abbreviations Declaration of conformity Declaration of conformity is available on the Internet.

Safety instructions WARNING! Obey the instructions in Safety instructions on page 13. If you ignore them, injury or death, or damage to the equipment can occur. 134 BTAC-02 pulse encoder interface module Hardware description Product overview The BTAC pulse encoder interface module (option +L535) adds a digital pulse encoder interface to the drive. Use a pulse encoder, if you need accurate speed or position (angle) feedback from the motor shaft. The BTAC module supplies power to the encoder. For more information, refer to Wiring – Encoder power supply interface on page 137. The BTAC module has the features of the BAPO-01 auxiliary power extension module. It provides back-up power to the drive. For more information, refer to BAPO01 auxiliary power extension module on page 157. Layout 1. BTAC module 2. Locking screw hole 3. X103 connector 4.
