5 Start Up
18 I67E-EN V1000 Quick Start Guide
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 applica-
tions the drive will control.
Auto-Tuning (T1-)
Auto-Tuning automatically sets up the motor data relevant drive parameters. Three different
modes are supported
Control Mode Parameter Main Applications
V/f Control
A1-02 = 0
(default)
• General variable speed applications, particularly useful for running multi-
ple motors from a single drive
• When replacing a drive in which parameter settings are unknown
Open Loop
Vector Control (OLV)
A1-02 = 2
• General variable speed applications
• Applications requiring high precision, high speed control
PM Open Loop
Vector Control
A1-02 = 5
• Derated torque-load applications employing permanent magnet motors
(SPM, IPM) and energy savings.

Description
Rotational
Auto-Tuning
T1-01 = 0 OLV
Perform when setting the drive to operate in Open Loop
Vector control. The motor must be able to rotate without
load during the tuning process in order to achieve a high
accuracy.
Terminal resistance
tuning
T1-01 = 2
OLV, V/f
control
Perform in V/f control if the motor cable is long or if the
cable has been changed.
Rotational
Auto-Tuning
for Energy Saving
T1-01 = 3 V/f control
Perform when using Energy Saving or Speed Search.The
motor must be able to rotate without load in order to achieve
a high tuning accuracy.
CAUTION
Never touch the motor until the Auto-Tuning is finished. Even thought the motor may not be
rotating when Auto-Tuning, voltage is still applied to the motor during the tuning process.
