About the B90H1015
Reliance Electric manufactures B90H1015, an enclosed motor that is part of the HR2000 drive series. The horsepower is 1, the continuous torque rating is 31.5 in-lbs, the base speed is 2000 rpm, and the inertia is 0.012 lb. in s^2. The associated chassis controller is 3RA2001. The flange mounting is an FF200 IEC flange. This motor is enclosed in a TENV enclosure.
The microprocessor uses the motor encoder to determine rotor position of B90H1015, which then converts the quadrature current/torque reference (ITR) to two motor line current reference. If a continuous pulse input is received by the controller, a constant speed will be maintained on the motor. The motor will decelerate to a stop if the contact is opened. Troubleshooting the motor may, as a last resort, involve disassembling and reassembling the motor. Follow all manual instructions carefully in order to avoid bodily injury and/or electrical damage. It is critical that the encoder is appropriately aligned when the motor is reassembled.
If the controller indicates an SFB (Speed Feedback) fault, possible causes include a miswired encoder (if the CPU LED is also illuminated), a motor-mounted encoder failure, and/or excessive motor rotational speed. An OC (Overcurrent) fault may be caused by a short in a power device, such as the motor, the output transistor, or the D-C bus components. A PL (Phase Loss) fault may be caused by an input phase loss. In a Phase Loss fault, there is a motor lead or motor ground present.
