4 How to Program
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.

Function:
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
The minimum reference unit matches:
• The choice of configuration in par. 1-00
closed-loop [1], RPM; for Torque
• The unit selected in par. 3-01
Function:
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
Torque
RPM; for [2], Nm.
• The unit selected in par. 3-00
Function:
Enter the ramp-up time, i.e., the acceleration time from 0 RPM to the synchronous motor speed
n . Choose a ramp-up time such that the output current does not exceed the current limit in
S
par. 4-18 Current Limit during ramping. The value 0.00 corresponds to 0.01 sec. in speed mode.
