If you have a non-functioning Avi 37 drive, do not throw it away immediately. These units are surprisingly repairable. Here is a standard troubleshooting flowchart used by motion control technicians:
Step 1: Visual Inspection Open the chassis (disconnect power first!). Look for bulging electrolytic capacitors or burnt resistors. The most common failure in drives of this age is capacitor dry-out.
Step 2: LED Status Codes The Avi 37 has a multi-color status LED.
Step 3: Encoder Feedback Check If the motor oscillates or runs away, the encoder feedback loop may be broken. Check the shielded cable between the motor and the Avi 37 for continuity on the A+, A-, B+, B- lines. techno avi 37
Step 4: Tuning Potentiometers Some Avi 37 variants feature physical potentiometers for adjusting loop gain (proportional, integral, derivative). If a previous user mis-tuned these, the drive will behave erratically. Reset them to factory default (usually 50% rotation) as a starting point.
To understand the Techno Avi 37, we must first look at its parent company. Techno, Inc. (often referred to as Techno-Isel) was a prominent manufacturer of automation equipment, including gantry robots, CNC routers, pick-and-place machines, and servo motion control systems. While the company has since shifted its primary focus or rebranded in certain markets, its hardware remains in high demand on the secondary market.
The "Avi" designation typically refers to a series of AVI (Advanced Video Interface) or, more accurately in technical documentation, a servo drive or motor controller unit. The Techno Avi 37 is widely understood to be a specific servo amplifier or driver module designed to control AC or DC servo motors in precision automation tasks. If you have a non-functioning Avi 37 drive,
In the context of Techno’s product lineup, the number "37" generally denotes a specific current rating (e.g., 3.7 amps continuous) or a specific model variant within the Avi series. Unlike consumer electronics, industrial part numbers like this one are meticulously structured: "Techno" for the brand, "Avi" for the product family, and "37" for the performance class.
The Techno Avi 37 is designed as a corded hair clipper for home use, particularly popular for cutting men's hair and beards.
