Procedure
Working Scope
Installation
Check inverter’s rated power, and install the inverter as per the requirements
stated in Chapter 2.
Wiring the Inverter
Wiring as per the requirements stated in Chapter 3, typical wiring diagrams as
shown in Chapter 12.
Check Before Power-on
1.
Be sure the input power supply is correct
2.
The input power supply circuit connects to a circuit breaker
3.
The inverter is grounded.
4.
Power supply cable is connected to input terminals R, S and T of the inverter
correctly
5.
Motor is connected to output terminals U, V, and W of the inverter correctly.
6.
The braking resistor is connected to PB and terminal
.
7.
Correct control circuit wiring.
8.
The external limit switches are connected to inverter, and the external
braking devices are connected to the control terminals of inverter.
Check at Power-on
1.
Check if there is unexpected noise, odd smell, or smoke with inverter.
2.
When power is on, normal display on control panel, without alarming.
3.
Turn off the power immediately if any emergency, and check as per the
instruction in Chapter 9.
After inverter maintained or motor changed, please reset the parameters as defaults, and then conduct
following operations.
Parameter Setting
F4-28 sets application macros, the default is F4-28=9 (Special for hoist). Please
confirm if F4-28 parameters are applicable to the applications. (Please set F4-28
parameters as per the instructions in 6.3)
Input Correct Motor Label
Parameter
1.
Input and confirm the parameters listed on motor nameplate. Otherwise,
serious damage may occur in operation.
2.
Set parameters of motor 1 in F1.
3.
For construction lift: if 2 motors are in parallel connection, the motor power
and the rated current shall set the sum of that of those 2 motors.
Setting Protection
Parameter of Motor and
Inverter
1.
Set correct limit parameters and protection parameters of inverter and
motor, mainly as: maximum frequency, upper-limit frequency, fault output,
and etc.
2.
Current limit protection and overvoltage stall protection are disabled for
hoisting devices.
Autotuning Motor
Parameter
1.
Obtain correct motor parameters by autotuning before the initial operation.
2.
If motor cannot be disconnected from the load, pleasese stationary
autotuning (F1-15=1), and then press ENTER.
3.
Please do not autotune motor parameters if the motor is running.
