V. function and use


Speed way


This driver provides the following speed regulation mode:


Panel speed regulation: by setting the internal speed parameters of the driver to achieve different speed.


External input speed will be an external potentiometer two fixed end connect to the GND and + 5 v end of the drive, will adjust the termination in the SV side can use an external potentiometer (5 k to 100 k) speed regulation, can also be controlled by other units (such as PLC, SCM, etc.) input analog voltage to the SV to achieve speed control (relative to the GND), SV port to accept in the range of DC OV ~ + 5 v, corresponding to the motor speed of 0 ~ rated speed.


Can also use external digital signal speed regulation: between SV and GND can be applied to the amplitude of 5V, frequency of 1KHz~2KHz pulse width digital signal (PWM) for speed regulation, motor speed by its duty cycle linear regulation.At this time, the amplitude of SV digital signal can be attenuated by 0-1.0 ratio by adjusting r-sv potentiometer. Generally, the r-sv is adjusted to 1.0, and the input digital signal of SV is not attenuated.


Motor operation/stop control (EN)


The on and off of the control terminal EN relative to GND can control the operation and stop of the motor.When the terminal is disconnected, the motor will stop.When the running/stopping end is used to control the motor to stop, the motor will stop naturally, and its motion law is related to the load inertia.


Motor forward/reverse control (F/R)


By controlling the on and off of terminal F/R and terminal GND, the running direction of the motor can be controlled.When F/R and terminal GND are not connected, the motor will run clockwise (facing the motor shaft), otherwise, the motor will run counterclockwise.In order to avoid the damage of the driver, when changing the motor steering, the motor should be stopped before changing the steering to avoid operating in the direction of the motor operation.


Brake stop


By controlling the on and off of terminal BK and terminal GND, the motor's braking and stopping can be controlled.When the control terminal BK is disconnected from the terminal GND, the motor runs, and when the motor is connected, the quick braking stops, and the braking shutdown is faster than the natural shutdown. The specific shutdown time is related to the load inertia of the user system.If there is no special stop requirement, natural stop should be adopted because the stop of braking has impact on electrical and machinery.


Motor speed signal output (PG)


The speed pulse output, the port for OC output (30 v / 10 ma Max), to get a signal with the power of the indirect 3 k Ω ~ 10 k Ω pull-up resistor.The terminal will output frequency and motor speed is proportional to the fixed pulse width (50uS) negative pulse string, motor per revolution of the output pulse number of 3 x N, N is the number of motor poles.Example: two pulses per revolution of a 2-pole, or quadrupole, motor.When the motor speed is 500 RPM, the output pulse of terminal PG is 1000.


Alarm output


Driver alarm output, the port is OC output (30V/10mA Max).To get a signal with the power of the indirect 3 k Ω ~ 10 k Ω pull-up resistor.When alarming, this terminal conducts with GND (low level), and at the same time, the driver stops working by itself and is in the alarming state.


Driver failure


The drive will automatically stop working and the motor will stop. The blue light on the drive is flashing. As long as the enabling end is reset (that is, EN is disconnected from GND) or the power is cut off, the drive can remove the alarm.Please check the motor wiring in case of this fault.

Vi. Display and keyboard operation


Note: "R/S" : represents start/stop (return key)


"+" : add 1 to the value of the parameter when setting the parameter


"-" : when parameters are set, the value of the parameter is reduced by 1


: ENTER


The key position is shown in the figure above:


6.1 system parameter setting method:


1. The system parameter setting must be in the state when the motor is stopped, that is, when the motor is in the stop state in panel mode or in the enable disconnection state in external port mode. In the case of standby, press "ENTER";Will call up system parameters, and then press ENTER key, will call up the setting value of system parameters.


2. Press "+" or "-" key to set the parameter you want to modify.If you do not want to change the "R/S" key to jump out of the setting, back to the standby state.


3. Press "ENTER" key again to see the parameter content.If you do not want to change the "R/S" key to jump out of the setting, back to the standby state.


4. Press the "+" or "-" key to adjust the parameter value you want to modify.


5. Press "ENTER" to store parameters, and press R/S to return to standby state.


Description: in the setting state, if no button is pressed for one minute, it will automatically jump to the speed display interface.


6.2 working mode:


There are two working modes of the driver, which can be set by the panel.Second is the external port working mode;Motor in accordance with the setting mode, digital tube display motor speed.In the working mode of the panel, press R/S key to start and stop the motor, long press + and - keys to increase and decrease the motor speed, and press given ENTER key to determine the motor speed.The motor runs at the set speed.


6.3 protection mode:


When the motor is abnormal during operation, the digital tube displays Err.


(1)Err1 means the motor is stuck.


Err2 represents over current.


(3)Err3 means hall fault.


Err4 represents input undervoltage.


Err5 means input overvoltage.


Err6 represents input peak current protection

Vi. System usage



First connected to the motor and drive in the attachment (motor winding lines, signal lines and power cord) hall, must be in strict accordance with the requirements of attachment, not like asynchronous motor by changing the wiring direction to turn, can lead to incorrect wiring is abnormal motor, or is not running, the main performance brush motor vibration or fever quickly (tens of seconds to two minutes, the temperature rise to 80 degrees c), and will damage the motor and drive.


Motor when the motor winding line, hole lines connect the power cord and drivers, can run, potentiometer to set the minimum first, and then press start switch, potentiometer slightly increase motor, the motor should be run, such as the motor is not running, or shiver, likely for motor line phase sequence is wrong, please check the order of the brushless motor fuses, again until it can realize the normal movement of the motor, stop.


Vii. Communication method:


The communication mode adopts standard Modbus protocol and conforms to national standard GB/T 19582.1 -- 2008.RS484 based double wire serial link communication is used, and the general telephone port is adopted for the physical interface. Connection 6 corresponds to A, connection 3 to B, and connection 8 to GND. The serial connection is very convenient.Transmission mode RTU, validation mode CRC, CRC start word FFFFH.Data mode 8 bit asynchronous serial, 2 stop bit, no effect bit, support a variety of communication rates (see the parameters table).


Note: if communication mode is required to control the motor, it must be carried out in internal speed regulation mode.


Function parameters support 03H multi-register read, 10H multi-register write, 41H state query.
