WIRING DIAGRAM

SAFETY

jIt is installed on anon-flammable metal frame to prevent the intrusion of dust, corrosive gases, conductive objects, liquids and flammable materials, and to maintain good heat dissipation conditions；

kThe drive is forbidden to withstand shocks；

l Do not connect the power input cable to the output U, V, or W terminals；

mVerify that the input supply voltage of the main circuit is within the allowable operating voltage range of the drive；

nDo not test the high voltage resistance and insulation performance of the driver at will；

oAccording to the illustrated method, correctly connect the power cable, motor winding cable, Hall signal cable and control signal cable, and note that the sequence of UVW three phases must be consistent.

uPlease have a professional electrical engineer carry out the wiring operation;

vBefore wiring, please confirm that the input power supply should be cut off and the wiring and inspection must be carried out after the power supply is cut off and driver indicator is off.

wWhen plugging and unplugging the terminal blocks of the driver, make sure the indicator light is off before proceeding

xIt is strictly forbidden to touch all terminals during power-on operation

y If the sequence between Hall and 3 phases of the motor is incorrect or didn’t proceed the self-learning to match the hall and 3 phase of the motor, the motor cannot operate normally, and if the value of VSP/PWM input is too large, the driver will be damaged.

zFor long-term work, please follow the radiator well, and keep the radiator and MOS tightly fitted;

WORKING MODE

The driver can work in two working modes, Hall and Hall, during the driver power-on, the driver detects the Hall signal, if the Hall signal is not connected, or the Hall signal is faulty, the driver will work in the Hall no mode of operation. Otherwise, the drive works in Hall mode of operation.

When the driver is enabled, when the control signal is greater than the starting duty cycle (configured through the serial port), the driver starts to start, and when the control signal is lower than the starting duty cycle, the driver is in standby mode and the motor stops.

There are a total of 6 combination sequences for Hall signals HU, HV, and HW, and one of them is the correct phase sequence. The correct phase sequence satisfies the following conditions: (1)the forward and reverse rotational speed and power are approximately equal, and (2)the output power and current are normal during the gradual increase of the ​command to the maximum. Note: During the testing of the phase sequence, the power supply needs to have a current limit measure to avoid accidents.

This driver supports Hall phase sequence self-learning Xi function, connect the power cable, Hall signal and control signal, ​serial port sends AA 01 1E 01 00 00 00 CC instructions, the driver performs Hall phase sequence self-learning Xi, LED flashes 13 times and turns off for 2 seconds to indicate that the learning Xi is completed, and the control instruction is zero, and it can work normally.

In Hall-free mode, the phase lines of the U, V, and W motors can be connected arbitrarily, and two of the phases can be ​exchanged arbitrarily, and the motor can be reversed, and the external F/R signal can also make the motor reverse. In Hall-free mode, the F/R signal can be configured via the serial port to take effect immediately or when the motor ​is stopped.
