: Adjust how quickly the motor reaches full speed or slows down.
Before operating the drive, ensure you have the correct input voltage and motor compatibility. : 115 VAC, 50/60 Hz. Output Rating : 0–90 VDC armature voltage. Horsepower Range : 1/100 to 1/3 HP. 2. Installation Steps bc138.rar
: You must install a Plug-in Horsepower Resistor® . This component automatically sets the drive’s IR compensation and current limit (CL) to match your specific motor’s horsepower. 3. Fine-Tuning (Trimpot Adjustments) : Adjust how quickly the motor reaches full
: This feature allows you to cycle the AC power rapidly without damaging the control or the motor. Output Rating : 0–90 VDC armature voltage
: Install the drive in a well-ventilated area using its NEMA-1/IP20 metal enclosure. You can reorient the front cover to allow for top or bottom wiring.
For detailed wiring diagrams and resistor selection charts, you should refer to the full BC138 - BC139 DC Control Manual . If you'd like, I can help you:
: Limits the maximum current to protect the motor from failure or demagnetization. 4. Safety Features
