Danfoss VLT AutomationDrive FC 300 Instruction Manual

Note:
• For the best adaptation of the adjustable frequency drive, run the AMA on a cold motor.
• AMA cannot be performed while the motor is running.
• AMA cannot be performed on permanent magnet motors.
NOTE!
It is important to set motor par. 1-2* correctly, since these form part of the AMA algorithm. An AMA must be performed to achieve
optimum dynamic motor performance. It may take up to 10 min, depending on the power rating of the motor.
NOTE!
Avoid generating external torque during AMA.
NOTE!
If one of the settings in par. 1-2* is changed, par. 1-30 to par. 1-39, the advanced motor parameters, will return to default setting.
3-02 Minimum Reference
Range: Function:
Application
dependent*
[Application dependant] Enter the Minimum Reference. The Minimum Reference is the lowest value obtainable by adding all
references together.
Minimum Reference is active only when par. 3-00
Reference Range is set to Min.- Max. [0].
The minimum reference unit matches:
• The choice of configuration in par. 1-00
Configuration Mode Configuration Mode : for Speed
closed-loop
[1], RPM; for Torque [2], Nm.
• The unit selected in par. 3-01
Reference/Feedback Unit .
3-03 Maximum Reference
Range: Function:
Application
dependent*
[Application dependant] Enter the maximum reference. The maximum reference is the highest value obtainable by adding
all references together.
The Maximum Reference unit matches:
• The choice of configuration in par. 1-00
Configuration Mode : for Speed closed-loop [1],
RPM; for
Torque [2], Nm.
• The unit selected in par. 3-00
Reference Range .

dependent*
[Application dependant] Enter the ramp-up time, i.e., the acceleration time from 0 RPM to the synchronous motor speed
n
S
. Choose a ramp-up time such that the output current does not exceed the current limit in
par. 4-18
Current Limit during ramping. The value 0.00 corresponds to 0.01 sec. in speed mode.
