NB!
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 summing
all references.
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 summing
all references.
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 .
3-41 Ramp 1 Ramp up Time
Range: Function:
Application
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.

3-42 Ramp 1 Ramp Down Time
Range: Function:
Application
dependent*
[Application dependant] Enter the ramp-down time, i.e. the deceleration time from the synchronous motor speed n
s
to 0
RPM. Choose a ramp-down time such that no over-voltage arises in the inverter due to regenerative
operation of the motor, and such that the generated current does not exceed the current limit set
in par. 4-18
Current Limit . The value 0.00 corresponds to 0.01 s in speed mode. See ramp-up time
