nameplate details
Refer to the Dyneo

motors tables located in the Appendix. Select the table corresponding to the motor
speed range (1500 or 3000 rpm). Then depending on the motor type and its power, select the line that
corresponds to the voltage, the supply frequency and the rated speed of the application. From this line,
set in the drive the values of all the parameters listed in the table.
If the load is a high inertia, Pr 03.010 may need to be increased.
NOTE : If the motor type does not appear in the table, then it is from the Compact range. In this
case, please contact Control Techniques Technical Support.
Example:
For the 1500 range motor, LSHRM 160MR1 - 11 kW 400V - 50Hz with a rated speed of 1500 rpm, parameter
values to set in the drive are the ones of the green line as indicated below:

NOTE: When setting Pr 05.069, it may be necessary to increase the value entered, to ensure that the
actual trip level displayed in Pr 05.068 is close to (but not greater than) the required value.
Additional settings
Set :
• RFC Feedback Mode (Pr 03.024) = Sensorless
• P1 Error Dectection Level (Pr 03.040) = 0
• P1 Thermistor Fault Detection (Pr 03.123) = None (0)
• Motoring Current Limit (Pr 04.005) = 120% max
• Regenerating Current Limit (Pr 04.006) = 120% max
• Symmetrical Current Limit (Pr 04.007) = 120% max
• Current Reference Filter 1 Time Constant (Pr 04.012) = 1 ms
[May need to increase this value to
counteract ripple from low resolution estimated feedback]
• Thermal Protection Mode (Pr 04.016) = Disabled (4)
• User Current Maximum Scaling (Pr 04.024) = 120% max
• Number of motor pole pairs (Pr 05.011) = 2
• Maximum Switching Frequency (Pr 05.018) = 3kHz (1)
• Enable High Speed Mode (Pr 05.022) = Enable (2)
• Flux Control Gain (Pr 05.027) = 0.1
• Minimum Switching Frequency (Pr 05.038) = 3kHz (1)
• Voltage Headroom Pr 05.041 = 5%. [Do not set a lower value. Increase this value to 10%, if the motor
is unstable in the eld weakening area]
• RFC Low Speed Mode (Pr 05.064) = Injection
• Saliency Torque Control Select Pr 05.065 = Auto (3) [Ensure that Pr 05.066 = High (2) otherwise
check the value entered for Pr 05.087 from the table]
• Inverted Saturation Characteristic (Pr 05.070) = On (1)
• Low Speed Sensorless Mode Current (Pr 05.071) = 60% [Note: This forces a reduced current limit
between zero speed and 20% of motor rated speed]
• Stop Mode (Pr 06.001) = Ramp (1)
• Hold Zero Speed (Pr 06.008) = Disabled (0)
Save parameters Select «Save Parameters» in Pr mm.000 and press the red reset button or toggle the reset digital input.
Start-up Drive is ready to start-up.
