Action Detail
Motor Setup
Unidrive M Connect contains a database for induction motors and permanent magnet motors.
Provision is also made to enter motor nameplate data.
The next section describes the use of the motor database for a Leroy Somer LSRPM motor
used in RFC-S Sensorless mode.
Motor Feedback
Setup
This only needs to be performed in RFC-A (with feedback) mode
Set Pr 03.024 = Feedback (0)
Enter:
• Encoder power supply in Pr. 03.036 = 5 V (0), 8 V (1) or 15 V (2).
If output voltage from the encoder is >5 V, then the termination resistors must be
disabled Pr 03.039 to 0.
• Drive encoder Lines Per Revolution (LPR) in Pr 03.034 (set according to encoder)
• Drive encoder termination resistor setting in Pr 03.039:
0 = A-A\, B-B\ termination resistors disabled
1 = A-A\, B-B\, termination resistors enabled
Motor Thermistor
Set-up
The motor thermistor connection may be made either:
Through the drive encoder port (terminal 15)
• Select thermistor type in P1 Thermistor Type (03.118)
•Set P1 Thermistor Fault Detection (
03.123
) to either Temperature (1) or Temp or Short (2)
Through terminal 8 (Digital Input 5 / Analog Input 3) of the control terminals (requires a drive
with date code 1710 or later and control firmware V01.13.00.00 or later).
• Change Analog Input 3 Mode (07.015) from Disable (0) to either Therm Short Cct (7) or
Thermistor (8).
• Select the thermistor type in Analog Input 3 Thermistor Type (07.046)
Ramps Setup
Enter the required Acceleration rate and Deceleration rate
Note: If a braking resistor is installed, set 'Ramp mode' to 'Fast'. Also ensure Pr 10.030 and
Pr 10.031 and Pr 10.061 are set correctly, otherwise premature 'Brake R Too Hot' trips may
be seen).
Autotune
Not required when using data from the motor database for a Leroy Somer LSRPM motor used
in RFC-S Sensorless mode.
Setting the encoder voltage supply too high for the encoder could result in
damage to the feedback device.
