backUnit]
Enter the minimum reference. The
minimum reference is the lowest
value obtainable by summing all
references.
Minimum reference is active only
when parameter 3-00 Reference Range
is set to [0] Min.- Max.
The minimum reference unit matches:
•
The conguration of
parameter 1-00 Conguration
Mode: for [1] Speed closed
loop, RPM; for [2] Torque,
Nm.
•
The unit selected in
parameter 3-01 Reference/
Feedback Unit.
If option [10] Synchronization is
selected in parameter 1-00 Congu-
ration Mode, this parameter denes
the maximum speed deviation when
performing the position oset
dened in parameter 3-26 Master
Oset.

The maximum reference unit
matches:

Enter the ramp-down time, that is, the
deceleration time from the synchronous
motor speed n

to 0 RPM. Select a ramp-
down time such that no overvoltage occurs
in the inverter due to regenerative operation
of the motor, and such that the generated
current does not exceed the current limit set
in parameter 4-18 Current Limit. The value
0.00 corresponds to 0.01 s in speed mode.
