7.3.4 RFC-S mode (Sensorless) Dyneo LSRPM motor set-up with V01.12.02.00 onwards firmware
Action
Ensure:
• The drive enable signal is not given (terminal 29).
Before power-up
• Run signal is not given
• Motor is connected
Verify that RFC-S mode is displayed as the drive powers up. If the mode is incorrect see section
5.6 Changing the operating mode on page 108, otherwise restore parameter defaults (see section
Power-up the drive
5.8 Restoring parameter defaults on page 109).
Ensure that the drive displays 'inhibit'
Enter:
• Motor rated current in Pr 00.046 (A)*
• Rated speed in Pr 00.045 (rpm)
• Volts per 1000 rpm in Pr 00.047 (V / 1000 rpm)
Enter motor
Motor rated voltage Pr 00.044 and number of motor poles Pr 00.042 are also required but the default
nameplate details
values in RFC-S mode for the Powerdrive F300 are set to match those required by the Dyneo LSRPM
motor.
From firmware version 01.12.xx.xx onwards, the rated current from the motor nameplate is entered into
Pr 05.007 / Pr 00.046 and will be updated automatically to the sensorless value after an autotune.
Enter:
Enter motor thermal
• Motor Thermal Time Constant value into Pr 00.053 (s) from the values specified inTable 7-3 to
data and switching
Table 7-9 .
frequency
• Switching frequency value into Pr 00.041 (kHz) from the values specified inTable 7-3 to Table 7-9 .
Enter:
Set maximum speed
• Maximum speed in Pr 00.002 (rpm)
Enter:
Set acceleration /
• Acceleration rate in Pr 00.003 (s to Pr 01.006)
deceleration rates
• Deceleration rate in Pr 00.004
Perform a stationary autotune. The motor must be at a standstill before an autotune is enabled.
To perform an autotune:
• Set Pr 00.040 = 1 or 2 for a stationary autotune. (Both perform the same tests).
• Close the drive enable signal (terminal 29).
• Press the green hand button.
• The upper row of the display will flash 'Auto Tune' during the test.
• Wait for the drive to display 'Inhibit'.
Autotune If the drive trips it cannot be reset until the drive enable signal (terminal 29) has been removed.
• Remove the drive enable from the drive.
If no trip occurs during or after the autotune then this indicates that the drive has been correctly set-up
and is ready to run the Dyneo LSRPM motor. If a User Trip 40 occurs, then this indicates that the motor
rated current or motor rated speed was not recognized as being a valid value for a Dyneo LSRPM
motor. Check the Rated Speed (Pr 00.045) and Rated Current (Pr 00.046) entered in the drive against
the Dyneo LSRPM motors listed in Table 7-3 to Table 7-9. Correct the values and perform an autotune
again.
In sensorless mode, when the motor speed is below Pr 00.045 / 10, a special low speed algorithm must
be used to control the motor. There are two modes available, with the mode chosen based on the
saliency of the motor. The Dyneo LSRPM motors have little or no saliency so require the non-salient low
speed mode to be used. Set Pr 00.054 to: Non-salient (1).
Check Saliency
Non-salient mode requires the ramp rate to be no slower than 5 s / 1000 rpm when operating in the
region below Rated Speed Pr 00.045 / 10. The drive contains a feature to ensure that the ramp rate
during the low speed region is at least 4 s / 1000 rpm. This feature is enabled automatically after a
successful set-up of the Dyneo LSRPM motor.
Select 'Save Parameters' in Pr mm.000 (alternatively enter a value of 1000 in Pr mm.000) and press red
Save parameters
Run Drive is now ready to run
* When using V01.11.01.00 firmware the Sensorless motor rated current must be used rather than the nameplate value (see Table 7-3 to Table 7-9
overleaf).
