Motor driver with integrated controller D30/5/4QF-E2 - 1

D30/5/4QF-E2 User Manual The D30/5/4QF-E2 is a small 4-quadrant digital controller for the control of brushless Boreasa blower up to 150 W. It can work with BLDC motors with or without Hall sensors. This well-priced and miniaturized OEM module seamlessly integrates into many applications. Features: • Set value input through PWM or external analogue voltage (0 ... +3.3 V) • • Parameters can be set through 4 external digital inputs (DigIN) Dual control loop: Speed and Current The output stage can be enabled or disabled Maximum output peak current limit adjustable up to 10 A Motor speed can be monitored with the «FG» output Status indication via «Ready» output Motor blocked protection (current limit for blocked motor) Standardized connector strip, pitch 2.54 mm and 2 mm Configurable fix current or fix torque mode is optional If the driver works in 4-quadrant mode, there needs to be a circuit in place to consume the brake energy. The driver works in Current Loop (default) or Speed Loop (optional) control mode. All control parameters are built in the driver software. Sufficient start up current is needed from the power supply when the motor (blower) ramps up. The ramp up time will be extended if the power supply can’t provide enough current. For developments Boreasa offers a comprehensive Interface/Evaluation Board: the D30/5/4Q-M2 board ( not compatible with Boreasa D50/5/4Q-M2 board when working in 4-quadrant mode).

Commissioning Instructions Power supply layout Any available power supply can be used, as long as it meets the minimum requirements shown below. During set up and adjustment phases, we recommend to mechanically separating the motor from the machine to prevent damage due to uncontrolled motion! Power supply requirements Nominal output voltage Absolute maximum output voltage Output current 24 VDC 35 VDC Depending on load: Continuous: max. 5 A Acceleration: short-time max.7.5 A  During controlled deceleration, the power supply must be able to buffer the back-fed energy e.g. in a capacitor.

Functional Description of Inputs and Outputs Digital input «DigIN1» «DigIN2» «DigIN3» and «DigIN4» Parameters can be set thru digital inputs «DigIN1», «DigIN2», «DigIN3», and «DigIN4». Inputs are connected to CPU IO pins. «DigIN1» and «DigIN2» are connected to SCI RXD and SCI TXD, so they may be designed for SCI communication interface. If all four inputs are connected to DIP switch, 10K pull-up resister should be connected to PIN21 (Vcc). If the input is connected to main CPU, a 200Ohm resistor needs to be connected to protect the driver CPU. Speed control input «VSP» The motor speed set...

The « VCL» inputs is used for setting the continuous output current limitation in the range of 0.5 to 7.5A (by default), or setting the continuous output current at a fix value (optional) so the motor or blower will work at fix current (or fix torque) mode. The current applied at the input « VCL » will stay available for an indefinite period of time. Note  The limiting value should be below the rated motor current (max. continuous current) as shown on the motor data sheet. Set value current To parameterize the preferred current limiting value, an external voltage between current limiting...

Panasonic EEUFC1J221S Rated voltage 63 V, Capacitance 220 µF, Ripple Current 1285 mA Rubycon 63ZL220M10X23 Rated voltage 63 V, Capacitance 220 µF, Ripple Current 1120 mA Nichicon UPM1J221MHD Rated voltage 63 V, Capacitance 220 µF, Ripple Current 1300 mA The D30/5/4QF-E2 has no built-in choke per phase. For the most motors and applications no additional motor chokes are necessary. In case of high power supply voltage +VCC and a motor with very low inductance the current ripple will become too high, additional chokes on the motherboard are needed. The minimum inductance of each choke can be...
