HVAC Drive H300 143
Issue Number: 3
7.3 Quick start commissioning / start-up
7.3.1 Open loop
Action Detail
Before power-up
Ensure:
• The drive enable signal is not given (terminal 29)
• 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
5.6 Changing the operating mode on page 116.
Ensure:
• Drive displays ‘Inhibit’
If the drive trips, see Chapter 13 Diagnostics on page 286.
Enter motor
nameplate details
Enter:
• Motor rated frequency in Pr 00.021 (Hz)
• Motor rated current in Pr 00.020 (A)
• Motor rated speed in Pr 00.019 (rpm)
• Motor rated voltage in Pr 00.018 (V) - check if or connection
Set maximum
frequency
Enter:
• Maximum frequency in Pr 00.011 (Hz)
Set acceleration /
deceleration rates
Enter:
• Acceleration rate in Pr 00.012 (s to Pr 1.006)
• Deceleration rate in Pr 00.013 (s from Pr 1.006)
Motor thermistor
set-up
The motor thermistor can be selected in Pr 07.011. Refer to Pr 07.011 for further information.
Autotune
The drive is able to perform either a stationary or a rotating autotune. The motor must be at a standstill
before an autotune is enabled. A rotating autotune should be used whenever possible so the measured
value of power factor of the motor is used by the drive.
• A stationary autotune can be used when the motor is loaded and it is not possible to uncouple the
load from the motor shaft. A stationary autotune measures stator resistance and transient
inductance of the motor and values relating to deadtime compensation from the drive. These are
required for good performance in vector control modes. A stationary autotune does not measure
the power factor of the motor so the value on the motor nameplate must be entered into Pr 05.010.
• A rotating autotune should only be used if the motor is uncoupled. A rotating autotune first performs
a stationary autotune before rotating the motor at
2
/
3
base speed in the direction selected. The
rotating autotune measures the power factor of the motor.
To perform an autotune:
•Set Pr 00.024 = 1 for a stationary autotune or set Pr 00.024 = 2 for a rotating autotune
• Close the Drive Enable signal (terminal 29). The drive will display ’Ready’.
• Close the run signal (terminal 24). The upper row of the display will flash ’Auto Tune’ while the drive
is performing the autotune.
• Wait for the drive to display ’Ready’ or ‘Inhibit’ and for the motor to come to a standstill.
If the drive trips, see Chapter 13 Diagnostics on page 286.
• Remove the drive enable and run signal from the drive.
Save parameters
Select 'Save Parameters' in Pr mm.000 (alternatively enter a value of 1001 in Pr mm.000) and press
the red reset button or toggle the reset digital input.

A rotating autotune will cause the motor to accelerate up to
2
/
3
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.
