VLT Decentral Drive FCD 302
Function:
•
The configuration of
parameter 1-00 Configuration
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 Configu-
ration Mode, this parameter defines
the maximum speed deviation when
performing the position offset
defined in parameter 3-26 Master
Offset.
Function:
Enter the maximum reference. The
maximum reference is the highest
value obtainable by summing all
references.
The maximum reference unit
matches:
•
The configuration selected
in parameter 1-00 Configu-
ration Mode: For [1] Speed
closed loop, RPM; for [2]
Torque, Nm.
•
The unit selected in
parameter 3-00 Reference
Range.
If [9] Positioning is selected in
parameter 1-00 Configuration Mode,
this parameter defines the default
speed for positioning.
Function:
Enter the ramp-up time, that is, the
acceleration time from 0 RPM to the
synchronous motor speed n . Select a ramp-

up time which prevents the output current
from exceeding the current limit in
parameter 4-18 Current Limit during ramping.
The value 0.00 corresponds to 0.01 s in
speed mode. See ramp-down time in
parameter 3-42 Ramp 1 Ramp Down Time.

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.
