: Fine-tune the motor's speed regulation under varying loads.
: The BC138 includes both AC line and armature fusing to prevent damage during catastrophic electrical failures. bc138.rar
: Limits the maximum current to protect the motor from failure or demagnetization. 4. Safety Features : Fine-tune the motor's speed regulation under varying loads
: 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) Installation Steps The drive comes factory-calibrated
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
The drive comes factory-calibrated, but you can use the internal trimpots to customize performance: : Set the minimum and maximum motor speeds.
: Use the barrier terminal block for connections. Secure the AC line inputs and the motor armature leads (A+ and A-) according to the BC138 Installation & Operating Manual .
