官方故障排除步驟

Message value: Drive object: All objects Reaction: NONE Acknowledge: NONE Cause: The bandwidth referred to the time slice clock cyc le of the function generator has either been set too low or too high. Depending on the time slice clock cycle, the bandwidth is defined as follows: Bandwidth_max = 1 / (2 * time slice clock cycle) Bandwidth_min = Bandwidth_max / 100000 Example: Assumption: p4830 = 125 µs --> Bandwidth_max = 1 / (2 * 125 µs) = 4000 Hz --> Bandwidth_min = 4000 Hz / 100000 = 0.04 Hz Note: p4823: Function generator bandwidth p4830: Function generator time slice clock cycle See also: p4823 (Function generator bandwidth), p4830 (Function generator time slice cycle) SINAMICS-Alarms Diagnostics Manual (DAsl), 03/2009 Remedy: Check the value for the bandwidth and adapt accordingly. Note: The alarm is reset as follows: - remove the cause of this alarm. - restart the function generator.
