September 2012 L0106101 BLY17MDA Series 24V, 10A Brushless Controller/Motor User’s Guide 910 East Orangefair Lane, Anaheim, CA 92801 e-mail: [email protected](714) 992-6990 fax: (714) 992-0471 website: www.anaheimautomation.com ANAHEIM AUTOMATION
September 2012 L0106102 BLY17MDA Driver Features • Constant Velocity Mode Within 5% • 400 - 4000 RPM Speed Range • 0.5V to 5V External Voltage Speed Control • 2-Quadrant Operation • Short Circuit Protection • Maximum Current Limit Setting at 10.0 Amps Peak • Open Drain Speed Out • Run/Stop and Direction Inputs • TTL-CMOS Compatible Inputs • Compact Size • Screw Type Terminal Block General Description The BLY17MDA is a compact construction that implements a DC Brushless controller and a DC Brush- less motor in one streamline package. With the two parts combined into one casing, the need to wire up the motor has been eliminated. The DC Brushless controller operates off 24VDC. The high-speed DC Brushless motor can operate at 4000RPM, can generate up to 35.4oz-in of continuous torque, and deliver as much as 105W, with the BLY17MDA4 offering. Using hall sensor feedback, the DC Brushless controller operates in a constant velocity mode within 5%. The driver is protected against over current (cycle-by-cycle), hall sensor error and under voltage. An external potentiometer (10K) or external voltage (0.5-5VDC) can be used to control the speed. The direction of the motor can be preset by the direction control input. A brake function can be done by grounding the Run/Stop input. Fault Protection A cycle-by-cycle over current protection is provided when the motor current level exceeding the cur- rent limit of 10A peak is produced. When the over current protection is activated, the controller shuts off the outputs to the motor. Closed Loop (Constant Velocity Mode) The driver is set for Closed Loop operation. Closed Loop operation is used for applications where speed regulation is needed. Under closed loop operation, the speed is regulated despite changes to the load and the power supply voltage.

September 2012 L0106103 Specifi cations Direction Input: (TB1, Pin 1) TTL-CMOS Compatible Logic “0” = 0 - 0.8VDC Logic “1” = OPEN The Direction Input is pulled up through a 10k ohm resistor. Run/Stop Input: (TB1, Pin 2) TTL-CMOS Compatible Logic “0” = 0 - 0.8VDC, Motor Stopped Logic “1” = OPEN The Run/Stop Input is pulled up through a 10k ohm resistor. V Speed: (TB1, Pin 3) To control the speed of the motor with an external DC voltage, a voltage from 0.5VDC (min) - 5VDC (max) must be applied with reference to AGND (TB1, Pin 5). Control Inputs: PG Output (TB1, Pin 4): An open drain signal pulse out is available at a rate of 5 pulses for 1 revolution. The maximum rating for the open drain output is 30VDC/50mA. RPM = 15 * PG OUT (in Hz) Output Current Rating: 10.0 Amperes peak per phase maximum operating current (5.0 amperes average per phase maximum operation current) Power Requirements: (TB1, Pins 8 and 9) 18VDC (min) - 36VDC (max) Operating Temperature: Heat Sink: 0° - 70°C Motor Run/Stop The motor run/stop feature allows the stopping of a motor by shorting out the bottom drives of the three phases. A low at this input allows the motor to STOP, while a high (open) input allows the motor to RUN. A low signal will cause rapid deceleration. RPM 15 * PG Out (in Hz) Motor Direction The motor direction feature allows the changing of the rotation of the motor. This input should not be changed while motion is in progress. A high (open) input causes the motor to turn in the CW direction, while a low at this input causes the motor to turn in the CCW direction. Speed Output The PG OUT Terminal (TB1 - Pin 4) is used to determine the speed of the motor shaft. An open drain signal pulse out is shown at a rate of 15 pulses for 1 revolution.
September 2012 L0106104 Speed Adjust Setting An external voltage is used to control the speed of the motor. The 0.5 - 5VDC analog voltage can be tied on VSPD (TB1 - Pin 3) with respect to AGND (TB1 - Pin 5). A ramp up profi le at start up on VSPD (TB1 - Pin 3) would alleviate excessive current draw from the power supply. When the motor is rapidly accelerated from standstill, current drawn from the power supply can measure up to ten times the rated motor current. This startup current spike can shutdown power supplies by tripping the power supply’s current limit. A ramp down profi le from max operating speeds would alleviate any back EMF generated. When the motor is rapidly decelerated or stopped from high speed, the motor phase advances and this “returned energy” voltage appears on the drive’s power supply pins. Returned energy voltages seen at the input pins in excess of 50V will change the driver. The maximum ramp times are determined per application. Both the ramp up and ramp down speed profi les would need to be done with an external controller. The maximum voltage that can be place on VSPD is 10V. A voltage exceeding 10V will cause damage to the driver. If a voltage other than 0.5V to 5V is needed to control the speed of the motor, contact Anaheim Automation for custom tuning of the VSPD input. Note: Avoid changing the direction of rotation when the motor is already run- ning in any one direction. The following instructions must be followed to prevent permanent drive failure due to over-current conditions that exist in dynamic direction reversals of the motor: 1. Stop the motor by grounding the Run/Stop input 2. Wait for a least 500mS 3. Change the direction with the DIRECTION input 4. Run the motor by removing ground signal on the Run/Stop input Heating Considerations The temperature of the motor should never be allowed to rise above 70° Celsius. If necessary, mount the unit to an additional heat sink or air should be blown across the heat sink to maintain suitable temperatures.
