GK3000 Quick Setup Test Manual

Check whether the input and output power wiring is correct and whether the input voltage is correct. It is recommended to connect the motor with no load for testing.

Take the 3-phase 220V/60Hz 0.75kW asynchronous motor as an example to set the parameters:

Group P0, operation parameter group setting
P0.00=0 (V/F control, used in occasions with low load, such as fans and pumps)
P0.01=1 (digital setting frequency is given mode, power-off memory)
P0.02=60 (running frequency setting–set according to actual needs)
P0.03=0 (running command channel is selected as panel operation)
P0.04=0 (running direction setting)
P0.05=60 (maximum frequency setting)
P0.06=60 (upper limit frequency setting)
P0.07=0.00 (lower limit frequency setting, minimum operating frequency)
P0.12=10 (acceleration time 10s)
P0.13=10 (deceleration time 10s)
Group P8, motor parameter group setting
P8.00=0 (select the motor type as ordinary asynchronous motor)
P8.01=0.8 (motor rated power – set according to the motor nameplate)
P8.02=220V (motor rated voltage – set according to the motor nameplate)
P8.03=3.45 (motor rated current – set according to the motor nameplate)
P8.04=60 (motor rated frequency – set according to the motor nameplate)
P8.05=1390 (motor rated speed–set according to the motor nameplate)
P8.37=2 (1 asynchronous motor static self-learning, 2 asynchronous motor dynamic self learning)
The above is a simple setting method, please refer to the complete instruction manual for detailed explanation.

If you connect a Single-phase motor, please make sure that the phase loss protection is off.
PA.13=0

External terminal control

Before operation, please ensure that the wiring is correct. The basic function parameters of group P0 have been set, and the motor parameters of group P8 have been set. (Refer to the Quick Setup
Test Manual for the setting method)
Setting parameters P0 function parameter setting:
P0.01=0 (set frequency by panel potentiometer)

0-10V control (CI port)

Before operation, please ensure that the wiring is correct, the basic function parameters of group P0 have been set, and the motor parameters of group P8 have been set. (Refer to the Quick Setup

Constant pressure water supply system

Take the 4-20mA pressure sensor access system as an example.
Before operation, please ensure that the wiring is correct, the basic function parameters of group
P0 have been set, and the motor parameters of group P8 have been set. (Refer to the Quick Setup
Test Manual for the setting method)
The left jumper plug CI needs to be connected with I (When the analog input is current input, 1mA current is equivalent to 0.5V voltage. Therefore, the voltage parameter converted from 4-20mA should be 2~10V)
P0.01=10 (constant pressure water supply parameter setting)
P0.03=1 (terminal run command channel)
P2.43=3.10 (lower limit of input voltage protection value)
P2.44=6.80 (upper limit of input voltage protection value)
P3.00=1 (X1 terminal function is defined as FWD forward function) Whether the button needs to be self-locking.
P3.01=2 (X2 terminal function is defined as REV reverse function)
P3.02=3 (X3 terminal function is defined as STOP)
P3.21=2 (CI minimum input voltage 0V)
P3.22=0 (the minimum CI corresponds to 0%)
P3.23=10 (CI maximum voltage input 10V)
P3.24=100 (the maximum CI corresponds to 100%)

P4.02=43 (alarm lower limit pressure output)
P6.30= (given pressure)
P6.31= (maximum pressure value)
P6.32= (minimum pressure value)
P6.33= (alarm pressure value, upper limit, to judge whether the pipe network is blocked)
P6.34= (alarm pressure value, lower limit, to judge whether the pipe network is short of water)
P6.35= (Wake-up pressure value, when the water consumption increases and the pipe network pressure is less than this value, it will enter the working state, and the VFD will run at full frequency at this time)
P6.36=0 (duration of wake-up pressure operation, full frequency)
P6.37= (sleep pressure level value, when the pipe network pressure is greater than this value, the frequency will gradually decrease to the sleep frequency )
P6.38=10 (sleep pressure level duration, the time that the pipe network pressure is continuously maintained at the sleep pressure level)
P6.39= (sleep frequency, running frequency before entering sleep)
P6.40=10 (sleep frequency continuous time, sleep frequency running time) 

Therefore, after the pressure drops to the wake level, the VFD runs at a higher sleep frequency (or at full frequency). After reaching the sleep pressure, the frequency is higher than the sleep frequency, gradually decreases and runs for a period of time (P6.38), then runs at the sleep frequency (P6.39) for a period of time (P6.40), and finally enters sleep. When the pressure value drops to the awakening position, repeat the action.

Modbus-RTU control

P0.01=9 (RS485 interface takes effect)
P0.03=2 (serial port running command takes effect)
P0.05=60 (maximum frequency, this frequency can be input manually or written by command 06)
PC.00=5 (9600BPS, =6 19200, =7 38400)
PC.01=3 (no checksum)
PC.02=1 (station number, =0 broadcast address)
PC.03=2 (0-20ms response delay)
PC.04=0 (serial port timeout is invalid, 0.1~60.0s)
PC.05=1 (standard Modbus protocol)

Executable code 03 read, 06 write (not save), 07 write (save)
Example address, the following are 0x hexadecimal 0x5000 address is the running speed percentage storage area, (read/write)
(Decimal, it needs to be converted to hexadecimal and written into VFD. The maximum value corresponds to the percentage of the maximum operating frequency of the VFD, such as

5000=50.00% of the maximum speed.)
5000 speed percentage (Read/Write)
5001 running frequency (Read only)
5002 bus voltage (Read only)
5003 output voltage (Read only)
