Alarm / Warning
Abnormal condition reported by the drive that may allow continued operation for a limited or indefinite time.
The Explain card
- Plain English
- An alarm on a drive is a condition that is abnormal and has not yet stopped anything. The drive keeps running and flags it, and it may become a fault if the condition continues.
- Example
- A drive reports a heat sink temperature warning at 85 degrees. It keeps running, and if the sink reaches 95 the warning becomes an overtemperature fault.
- Why it matters
- Warnings are the drive's early notice, and a plant that only watches for faults misses them. Bring the warning bit to the HMI and the overtemperature that stops production in August becomes a fan replacement in June.
- Hook
- The drive clearing its throat before it shouts.
