6.2 Quick Start commissioning / start-up
6.2.1 Open loop
Action Detail
Before
power-up
Ensure:
• The drive enable signal is not given (terminal 11 and 13)
• Run signal is not given
• Motor is connected
Power-up
the drive
Verify that Open Loop mode is displayed as the drive powers up. If
the mode is incorrect see section 4.7 Changing the operating
mode
on page 19.
Ensure:
• Drive displays ‘Inhibit’

Enter:
• Acceleration rate in Pr 00.003 (s /100 Hz)
• Deceleration rate in Pr 00.004 (s /100 Hz) (If braking resistor
installed, set Pr 00.015 = FAST. Also ensure Pr 10.030,
Pr 10.031 and Pr 10.061 are set correctly, otherwise premature
‘Brake R Too Hot’ trips may be seen).
Motor
thermistor
set-up
The motor thermistor connection is made through the drive encoder
port (terminal 15). The thermistor type is selected in P1 Thermistor
Type (03.118).
Autotune
The drive is able to perform either a stationary or a rotating auto-
tune. The motor must be at a standstill before an auto-tune is
enabled. A rotating auto-tune should be used whenever possible so
the measured value of power factor of the motor is used by the drive
• A stationary auto-tune can be used when the motor is loaded
and it is not possible to uncouple the load from the motor shaft.
A stationary auto-tune measures the stator resistance of the
motor and the voltage offset in the drive. These are required for
good performance in vector control modes. A stationary auto-
tune does not measure the power factor of the motor so the
value on the motor nameplate must be entered into Pr 00.043.

A rotating auto-tune will cause the motor to accelerate
up to

base speed in the direction selected regardless
of the reference provided. Once complete the motor will
coast to a stop. The enable signal must be removed
before the drive can be made to run at the required
reference.
The drive can be stopped at any time by removing the
run signal or removing the drive enable.
