Section 1 General Information General Information 1-1 Introduction Baldor Series BSC 7107 control is a general purpose brushless DC motor control. This control commutates power into standard 3-phase brushless (BLDC) motors. The control input line voltage is 120 V AC ± 10%.
1-2 General Information Limited W arranty Fo r a period of one (1) year from the date of original purchase, BALDOR will repair or replace without charge controls and accessories which our examination proves to be defective in material or workmanship.
General Information 1-3 Safety Notice This equipment contains voltages that may be as great as 1000 volts! Electrical shock can cause serious or fatal injury . Only qualified personnel should attempt the start-up procedure or troubleshoot this equipment.
1-4 General Information W ARNING: Be sure the system is properly grounded before applying power . Do not apply AC power before you ensure that all grounding instructions have been followed.
Section 2 Receiving & Installation Receiving & Installation 2-1 Receiving The control is thoroughly tested at the factory and carefully packaged for shipment. When you receive your control, there are several things you should do immediately . 1.

2-4 Receiving & Installation Sensor and Motor Connections Refer to Figure 2-2. Brushless DC motors have eleven (1 1) wires: three (3) motor phase power wires, three (3) hall sensor wires, two (2) wires for hall sensor power and sensor common, one (1) wire for motor ground and two (2) wires for motor thermal switch.
Receiving & Installation 2-5 Reverse Operation T erminal P4–REV is the forward/reverse control. Y ou can reverse motor direction by connecting P4–REV to P4–COM. Use a jumper wire, switch, relay , or an open collector NPN transistor . Caution: Before reversing directions, make sure the motor is stopped.
2-6 Receiving & Installation 1st Time Power Up Procedure (or after a motor is replaced) Caution: If full AC V oltage is applied and the motor connections are wrong, the control will be damaged. Apply 10% of the input voltage to test motor lead connections at the first time power up or after a motor is replaced.
Section 3 Adjustments Adjustments 3-1 Current Limit Adjustment The current limit adjustment is factory set at 10 AMPS and you should not have to increase this setting for the Series BSC 7107 control. Rotating the I Limit potentiometer on the upper board CCW decreases the current limit.
3-2 Adjustments Minimum Speed Adjustment 1. Set the Speed Pot to zero speed (fully CCW). 2. Set the MIN pot on the upper board (Figure 2-2) fully CCW . 3. Apply power to the control. 4. Slowly rotate the MIN CW until the motor begins to rotate. Then turn the pot CCW until the motor just stops.
