3-02 Minimum Reference
Range:
Function:
0.000 Unit* [-100000.000 - par. 3-03]
The
Minimum reference
is the minimum value obtained by the sum of all references.
Minimum
reference
is only active if
Min - Max
[0] is set in par. 3-00.
3-03 Maximum Reference
Range:
Function:
1500.000* [Par. 3-02 - 100000.000]
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. 3-01

3-41 Ramp 1 Ramp-up Time
Range:
Function:
Size related [0.01-3600.00 s]
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 during ramping. The value 0.00 corresponds to 0.01 sec. in speed mode. See ramp-down time
in par. 3-42.

3-42 Ramp 1 Ramp-down Time
Range:
Function:
Size related [0.01-3600.00 s]
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 so that no overvoltage arises in the inverter due to regenerative
operation of the motor, and so that the generated current does not exceed the current limit set in
par. 4-18. The value 0.00 corresponds to 0.01 s in speed mode. See ramp-up time in par. 3-41.
