DBL048 Series

● It can be connected to a speed display to monitor the speed; It can also be connected to a computer to set the drive parameters
● Double closed-loop design of current and speed, large torque at low speed with stable operation
● High torque and high speed output, the maximum speed can reach 10,000 rpm / min
● The method of controlling the speed: 0 ~ 5V analog quantity (according to customer requirements can set 100 Hz ~ 100KHz PWM to control the speed)
● There are EN (enable), DIR (direction), X1 (brake) signal control pins
● Can output speed measuring pulse
● With over-current, over-voltage, under-voltage, rotor-blocked and other protection functions

▍Electric Connection

Type Terminal Symbol Description
RS232 TTL It can be connected to the speed display to monitor the speed; it can also be connected to the handheld setting unit to set the driver parameters. For details, please refer to the instructions of the handheld setting unit.
Control Signal Connections
+5V1 Control signal power supply is positive (built-in power output)
VSP External speed control signal
Control method:
The VSP terminal voltage is changed by an external potentiometer to achieve 0 ~ 100% speed adjustment, the range is 0 ~ 5V
FG Motor speed pulse output can be converted to the actual motor speed by measuring the frequency of this signal
DIR The high and low potentials control the motor forward and reverse.
– connect the GND1 motor to reverse (counterclockwise)
– not connect the GND1 motor or +5V1 to forward (clockwise)
EN Motor enables control.
– EN connects to GND1, the motor turns (connected state)
– EN does not connect, the motor does not turn (offline state, the red light in this state is always on)
GND1 Control signal power ground
Hall Signal Terminal
+5V2 Motor hall power supply is positive
HU Hall sensor signal U-phase input
HV Hall sensor signal V-phase input
HW Hall sensor signal W-phase input
GND2 Motor hall power ground
Motor and Power Supply Terminal
U、V、W Connect to the motor three-phase winding
GND、V+ DC18V~50V Power supply input (panel label:DC24V〜48V)
