Drive Setup Procedure
The illustration below shows the basic setup procedure. Each step is explained more detailed on the following pages.
Power On
Before turning on the power supply,
• Make sure all wires are connected properly.
• Make sure no screws, loose wire ends or tools are left in the drive.
• After turning the power on, the drive mode display should appear and no fault or alarm should be displayed.
Control Mode Selection (A1-02)
There are three control modes available. Select the control mode that best suits the application the drive will control.
Control Mode Parameter Main Applications
V/f Control for Induction
Motors
A1-02 = 0
(default)
• General variable speed applications, particularly useful for running multiple motors from a
single drive.
• When replacing a drive in which parameter settings are unknown.
V/f Control with PG Speed
Feedback
A1-02 = 1
• For general-purpose applications that do not require high dynamic response but high speed
accuracy.
• This mode should be used if the motor parameters are unknown and Auto-Tuning cannot be
performed.
Open Loop Vector Control A1-02 = 2
• General variable speed applications
• Applications requiring high precision, high speed control
Closed Loop Vector
Control
<1>
A1-02 = 3
• For general, variable-speed applications that requiring precise speed control down to zero
speed, fast torque response, or precise torque control.
• A speed feedback signal from the motor is required.
Install and wire the drive as explained.
Turn the power on.
Set the control mode.
Set/check the basic parameters:
* b1-01, b1-02 for frequency reference and RUN command source
* H1-, H2-, H3-, H4-, H6- to configure the I/Os
* Frequency reference values
* C1-, C2- for Acceleration/Deceleration times and S-curves
Run the motor without load, check the operation and verify, if the
upper controller (e.g. PLC,...) commands to the drive work as
desired.
Connect the load, run the motor and check the operation
Fine tune and set application parameters (e.g. PID,...) if necessary.
Final check the operation and verify the settings.
Drive is ready to run the application
START
Perform Auto-Tuning or set the motor data manually.
Initialize the drive if necessary using parameter A1-01.
Select Normal / Heavy Duty
