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:
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
: 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 . bc138.rar
: The BC138 includes both AC line and armature fusing to prevent damage during catastrophic electrical failures.
: This feature allows you to cycle the AC power rapidly without damaging the control or the motor. For detailed wiring diagrams and resistor selection charts,
The drive comes factory-calibrated, but you can use the internal trimpots to customize performance: : Set the minimum and maximum motor speeds.
: 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. Output Rating : 0–90 VDC armature voltage
The documentation for typically contains the instruction manual and setup files for the Baldor BC138 DC Motor Control . This device is a high-performance SCR drive used to control the speed of fractional horsepower permanent magnet (PM) DC motors. 1. Getting Started
