Issue Number: 5
7.2.4 RFC-S mode (Sensorless) Dyneo LSRPM motor set-up with V01.12.02.00 onwards
firmware
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 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 52, otherwise restore parameter defaults (see
section
5.8
Restoring parameter defaults on page 53).
Ensure that the drive displays ‘inhibit’

details
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)
Motor rated voltage Pr 00.044 and number of motor poles Pr 00.042 are
also required but the default 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:
• Motor Thermal Time Constant value into Pr 00.053 (s) from the
values specified inTable 7-3 to Table 7-9.
• Switching frequency value into Pr 00.041 (kHz) from the values
specified in Table 7-3 to Table 7-9.

rates
Enter:
• Acceleration rate in Pr 00.003 (s to Pr 01.006)
• Deceleration rate in Pr 00.004
Autotune
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'.
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.
* 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 on page 79).
