Parameter Group 7-** Controllers; Speed Pid Droop - Danfoss VLT AutomationDrive FC 301 Programming Manual

Programming Guide | VLT® AutomationDrive FC 301/FC 302
Setup: All setups
Data type: Int16
Scales the minimum output of the selected analog signal on terminal X45/3. Scale the minimum value as a percentage of the maximum
signal value, for example, 0 mA (or 0 Hz) is required at 25% of the maximum output value and 25% is programmed. The value can never
exceed the corresponding setting in parameter 6-82 Terminal X45/3 Max. Scale if the value is below 100%. This parameter is active when
VLT® Extended Relay Card MCB 113 is mounted in the drive.
6-82 Terminal X45/3 Max. Scale
Default value:
100%
Setup: All setups
Data type:
Int16
Scale the maximum output of the selected analog signal at terminal X45/3. Set the value to the maximum value of the current signal
output. Scale the output to give a current lower than 20 mA at full scale, or 20 mA at an output below 100% of the maximum signal
value. If 20 mA is the required output current at a value between 0–100% of the full-scale output, program the percentage value in the
parameter, for example 50% = 20 mA. If a current 4–20 mA is required at maximum output (100%), calculate the percentage value as
follows (example where required maximum output is 10 mA):

6-83 Terminal X45/3 Bus Control
Default value: 0%
Setup: All setups
Data type: N2
Holds the level of analog output 4 (terminal X45/3) if controlled by bus.
6-84 Terminal X45/3 Output Timeout Preset
Default value:
0%
Setup: 1 setup
Data type:
Uint16
Holds the preset level of output 4 (X45/3). If there is a fieldbus timeout and a timeout function is selected in parameter 6-80 Terminal
X45/3 Output, the output is preset to this level.

Speed PID Droop

6.9.1
This feature implements precise torque sharing between multiple motors on a common mechanical shaft. Speed PID droop is useful
for marine and mining applications where redundancy and higher dynamics are required. Speed PID droop allows to reduce inertia by
utilizing multiple small motors instead of 1 large motor.
