All rights reservedSINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition36951 $MA_SAFE_VELO_SWITCH_DELAYMD number Delay time, speed changeoverDefault value: 0.1 Min. input limit: 0 Max. input limit: 60Change becomes effective after: Power ON Protection level: 7/2 Units: sData type: DOUBLESignificance: A timer with this value is started when changing from a high to a lower safely-reducedspeed - or when a safe operating stop is selected when the safely-reduced speed functionis active.The parameterized value must be selected as low as possible.While the timer is running, the speed continues to be monitored against the last selectedspeed limit value. During this period, the axis/spindle can be braked, for example, from thePLC user program, without the monitoring function signaling an error and initiating a stopresponse.corresponds with...Special cases, errors,... 1. The timer is immediately interrupted as soon as a higher or identical SG limit (i.e. tothat which was previously active) is selected.2. The timer is immediately interrupted if “non-safe operation” (SGE “de-select SBH/SG=1) is selected.3. The timer is re-triggered (restarted) if, while the timer is running, a changeover is madeto a lower SG limit than was previously active or to SBH.36952 $MA_SAFE_STOP_SWITCH_TIME_CMD number Transition time, STOP C to safe operating stopDefault value: 0.1 Min. input limit: 0 Max. input limit: 10Change becomes effective after: Power ON Protection level: 7/2 Units: sData type: DOUBLESignificance: This machine data defines the time period between the initiation of a STOP C and theactivation of a safe operating stop.The parameterized value must be selected as low as possible.After the time has expired, the drive is monitored for a safe operating stop. If theaxis/spindle was still not able to be stopped, STOP B/A is initiated.corresponds with...36953 $MA_SAFE_STOP_SWITCH_TIME_DMD number Transition time, STOP D to safe operating stopDefault value: 0.1 Min. input limit: 0 Max. input limit: 60Change becomes effective after: Power ON Protection level: /2 Units: sData type: DOUBLESignificance: This machine data defines the time period between the initiation of a STOP D and theactivation of a safe operating stop.The parameterized value must be selected as low as possible.After the time has expired, the drive is monitored for a safe operating stop.
