Section 2: Functions
Run At Given Set Point:
This command causes the motor to start spinning at the set point
speed. The set point value is in RPM. When the Set Point speed is too high for the motor or the
controller to reach or if the load is too much for the motor to handle, the motor will run at the
maximum speed possible. The motor will also run at the given set point with RUN/STOP input.
Note: If the motor is started Digitally, it has to be stopped digitally. And if it is started with the
RUN/STOP input, it has to be stopped through the RUN/STOP input.
Hard Brake:
This command causes the motor to come to an immediate stop. If the motor is
moving fast, it will experience a jerk motion.
Coast:
This command causes the motor to stop with a constant deceleration and therefore motor
will not experience a jerk-like motion.
Go Clockwise:
This command changes the direction of the motor to clockwise.
Go Counter-clockwise:
This command changes the direction of the motor to counterclockwise.
Analog Input
: One can start the motor in Analog mode via the BMC100 software of Analog
Run/Stop Input. To set the speed Analog Voltage Input will read a voltage between 0 and
+5VDC and based on the ”upper and lower” limits of the function, a set point speed will be
calculated for the motor to go to between the two limits. For example, if the lower limit is set to
0 RPM and the upper limit is set to 5000 RPM, and the analog input is set at +2.0VDC, then the
motor will go to set point of 2000 RPM. Changing the lower limit to 1000 and the voltage to
+3.2VDC, the motor will go to set point of 3560 RPM.
See examples below for calculations of the analog inputs.
(Upper-Lower) * (Voltage/5) = X
Lower + X = Frequency
Speed(rpm) = Lower Limit + ((Upper Limit - Lower Limit) * (Analog Voltage/5))
Example1: If Analog Voltage = 2V
Speed = 0 + (5000 - 0) * (2 / 5) = 2000 RPM
Example2: If Analog Voltage = 3.2V
(5000 - 1000) * (3.2 / 5) = 2560
1000 + 2560 = 3560 RPM

/Stop Input:
Grounding this input will cause the motor to turn on in either Mode and
making it High will stop the motor using either Coast or Hard Brake depending on which
command was used last. If Coast was used last, it will Coast.
Set Address:
This command sets the address of the Controller.
