Product Overview
JKBLD720 brushless DC motor driver is our company's latest high-tech product for the field of medium power motor drive. This product uses a large-scale integrated circuit to replace the original hardware. It has higher anti-jamming and fast response ability. It is suitable for all the three-phase brushless DC motors with low voltage DC18V-50V(boards show DC24V-48V) and peak current below 15A. Even if working with large current, it is still in low temperature. It is widely used in knitting equipment, medical equipment, food packaging machinery, power tools and a series of areas of electrical automation and control.

Note: Due to dramatic changes in the temperature of the storage environment, it is easy to form condensation or frost. In this case, the drive should be placed for 12 hours or more. Until the drive temperature and ambient temperature is consistent, it can be on power.
Function | Mark | Description |
Indicator light | POWER | If the green power indicator is lighten, it shows that power is normal. |
| ALM | If the red status indicator is slow flash, it means waiting; Quick flash means operation; It always lights meaning faults or off-line; |
RS232 communication port | TTL | It can be connected with an external speed display board ZM-BL01 to display speed. ZM-BL01 can also set the drive parameters. Details are shown in ZM-BL01 instructions |
Control signal port | +5V1 | Control signal power+( inner power output ) |
| VSP | External speed control signal |
| X1 | Input signal, brake on low level or to GND1, the red light keep off(Brake braking force can be adjusted by customer’s requirement),When X1 is connected with +5V1 or without any port , motor keeps running. |
| FG | Motor speed pulse output is measuring the frequency of this signal. Then converts it into the actual motor speed. |
| DIR | Rotary direction is controlled by high and low electrical level, motor forward: connected with GND1, motor reversal （anticlockwise） ;without GND1 or connected with +5V, motor forward (clockwise) |
| EN | Connected EN with GND1, motor can work(online status);without connected or high electrical lever, motor can not work(offline status and the red light keep working) |
| ALM | It is signal transfer output. When the power is in danger, the current flow is slow. |
| GND1 | Control signal’s power supply |
Hall control port | +5V2 | + motor’s Hall power |
| HU | Hall sensor signal U phase input |
| HV | Hall sensor signal V phase input |
| HW | Hall sensor signal W phase input |
| GND2 | The motor’s Hall power supply |
The motor and power | U、V、W | The motor’s three-phase output signal |
| GND、V+ | GND、V+ stand for direct current flow. The input power is DC18V～50V.(boards show DC24V-48V) |
Speed mode (VSP/PWM) | 1. The external input speed: two external terminals of the external potentiometer(5K-10K) respectively connected to the driver's GND1 and +5 V1 terminal. If the regulator is connected to the VSP end, you can use an external potentiometer to adjust speed. It can also be made by the other control unit’s (such as PLC, microcontroller, etc.) input analog voltage to VSP side (relative to GND1). VSP port accepts the range of DC 0V ~ +5 V and the corresponding motor speed is 0 ~ rated speed; |
Brake | By control the high and low electrical level between X1 to control the motor status. On low electrical level,X1 stop, when the brake working, the red light off; when X1 is on high electrical level status or without connecting, motor can be allowed to work(Brake braking force can be adjusted by customer’s requirement) |
Speed signal output | The drive provides the motor speed pulse signal, which is positive proportion to the motor speed, pulse output way: RPUP 4.7k, open collector output |
The motor positive and negative signal（DIR） | By controlling high low-level of DIR to control the motor’s positive and reverse turn. |
Start/Stop signal（EN） | By controlling high low-level of EN to control the motor’s stop and run. When EN is low level, motor run; when EN is high level or non-connect ,motor stop working, red light keep working. When control motor stop by EN port, it is nature stop, and the run regular is related with overloading inertia. Power Consumption is less than or equal to 30mA. |
Alarm signal (ALM) | Normal output is 5V. When there is over-voltage, over-current, wrong Hall signal or the stop in the motor, the signal is 0V,the red light keep working. |
Attention
The drive should be installed with good ventilation. You had better regularly check whether the cooling fan is working properly. There are multiple drives in the cabinet. When they are used at the same, you had better ensure that the distance between each other is not less than 5 cm.
To ensure safety, you had better make sure that the grounding protection terminals of the drive are properly connected to the device!
★ The motor and drive wiring must be connected in the power-off state. Do not connect electrical wiring under power.
★According to the illustrated method, connect the power cord, motor winding wire and Hall signal line correctly. Please pay attention to the order of UVW three-phase must be consistent.
★Do not disassemble the drive at random to prevent damage.
★Do not touch all terminals on power-on state.
★ Do not drive without shell operation
★Impact of the drive may cause damage.
1. How can get it started as soon as possible when you first use the drive?
After you correctly connect the power cord, the motor line, the Hall line, the external potentiometer slowly accelerates. After the motor is turned correctly, you can test the enable, direction and other functions. If you are unfamiliar with the product, the initial use should be done after the test. And then it can be installed to the actual use.
2. What will come about if power supply is reverse?
It will immediately burn the drive.
3. What is the maximum of the upper control signal voltage ?
The maximum voltage of the speed regulation signal is 5V. Exceeding this voltage will cause the drive to burn.
4. After the driver has been working for a long time, the shell is hot. Is it normal?
Yes, it is. At room temperature, after long working hours, it is up to 90 degrees. And it will not affect the performance.
5. The power indicator is light, but the motor does not turn and shift, what is the reason?
There may be a mistake in the phase line and the Hall line. Please re-energize the wiring according to the motor manual.
6. Can my motor speed transferred to 6000 with this drive?
The maximum speed of the brushless motor is determined by the parameters of the motor itself. The drive can control the motor speed from 0 to the highest speed.
7. I already have a motor and how to install this drive after wiring?
You must first determine the motor phase and the definition of the Hall line, and then you can connect it with wires. If you are not sure, you need to ask the motor manufacturers. Incorrect wiring can cause damage to the drive.
8. Can I add some features on this drive or do new product development?
Yes, please contact us.
