DC Tachometer Input
If Tachometer Feedback is used, Jumper J5 must be in the TFB position and an analog tach signal must
be connected to TB1, terminals 1 and 2. The IR COMP Trimpot must be set to minimum, fully CCW.
Connect the tachometer so that when the motor rotates in the desired forward direction the positive
tach voltage lead is connected to terminal 1 and the negative lead to terminal 2. See Figure 2-7.
Note: If the Tachometer leads are connected backwards, the motor will run at full speed and will not
respond to a speed reference signal. Verify position of Jumper J5 is in TFB and the tach signal
polarity is correct.
Startup and Adjustments
Motor Type
The BC200/BC201™ is a full wave regenerative, bi-directional control used to operate Permanent
Magnet, (PM), and Shunt Wound DC motors. Do not use the control in applications where specified
ratings would be exceeded.
Torque Requirements
When replacing an AC induction motor with a DC motor and speed control, consideration must be
given to the maximum torque requirements. The full load torque rating of the DC motor must be equal
to, or greater than, that of the AC motor.
Set Jumpers
The BC200/BC201 have selectable jumpers which must be set before the control can be used.
Refer to Figure 2-1 for jumper locations.
J1A, J1B - Input AC Line Voltage
Select proper input line voltage, 115VAC or 230VAC, by placing both jumpers (J1A and J1B) in the
correct corresponding position, 115 or 230. Factory set for 230VAC shown in Figure 2-8.
J2 - Armature Current
Select the J2 position (2.5, 5, 7.5, 10, 15) closest to the rated motor current. See Figure 2-8 and Table 2-5.
Note: The maximum output current is set to 150% of the J2 position, which may be readjusted using the
FWD CL and REV CL trimpots. On Model BC200, position 10A is factory setting.
