A "bb" alarm in a Yaskawa drive signifies a Base Block condition. This indicates that the output power to the motor has been intentionally blocked. It's not necessarily a fault, but rather a state whe...

An Alarm 38 on a Danfoss VLT drive indicates an internal fault. This means there's a malfunction detected within the drive itself, preventing it from operating normally. Here's what you should know ab...

Cause : Ground Fault comes when a current path to earth ground has been detected at one or more of the drive output terminals. In Allen-Bradley drives, Fault Code 13 indicates a Ground Fault. This me...

Cause : HW OverCurrent comes when the drive output current has exceeded the hardware current limit. "HW OverCurrent" typically refers to a hardware overcurrent fault in drive. An Allen-Bradley fault c...

Cause : PU stop comes when the motor is stopped using STOP/RESET button under the mode other than the PU operation mode. (To enable STOP/RESET button under the mode other than the PU operation mode, s...

An NC (Normally Closed) contact is the opposite of an NO (Normally Open) contact. It's a type of switch or relay contact that remains closed (conducts electricity) in its un-energized state. This mean...

A Normally Open (NO) contact is a type of switch or relay contact that remains open (doesn't conduct electricity) in its un-energized state. This means when the switch isn't actively flipped or the PL...

NO and NC (Normally Open and Normally Closed) describe the resting state of a switch or relay contact, referring to whether it allows current to flow when not actively switched. They are crucial compo...

NO and NC stand for Normally Open and Normally Closed. They are terms used in various fields, especially common in: Electrical Engineering: They describe the default state of contacts in relays and s...

The key difference between NO (Normally Open) and NC (Normally Closed) lies in their default state when not energized: Normally Open (NO): Think of a light switch. In its normal state (off), the NO c...

NO and NC stand for Normally Open and Normally Closed, and they are terms used to describe the state of contacts in a Programmable Logic Controller (PLC) program or real-world electrical circuits like...

NO and NC stand for Normally Open and Normally Closed, and they are terms used to describe the state of contacts in a Programmable Logic Controller (PLC) program or physical input devices like switche...

A Delta drive CP30 error code indicates an internal communication error. This means there's an issue with communication within the drive itself, potentially between different internal components or th...
