Fieldbus data IN selections 1 to 8 “FB data in X sel”
Using these parameters, you can control any monitoring or parameter value from the
fieldbus. Enter the ID number of the item you wish to control for the value of these
parameters. Monitoring signals that can be controlled from fieldbus are shadowed.

P1.13.19

Fieldbus general status word
With this parameter it is possible to select which data are sent in
FBGeneralStatusWord (see for details and availability in used fieldbus manual).
P1.13.20
1741
FB actual speed “FBActualsSpeed”
With this it is possible to select which Actual speed is shown on the fieldbus.
0 = Calculated
This selection shows what the ramp generator output is.
Open Loop
In frequency control mode when only the ramp output is shown on the fieldbus and,
therefore, the motor slip or any other changes of speed due to load changes are not
visible in the actual speed value. However, limiting functions are visible in the ramp
output.
Closed loop
In closed loop control, the limiting functions take place after ramp generator.
When speed is limited by e.g. motoring torque limit the actual shaft speed may be
lower even if FB Actual Speed shows that speed is at reference.
1 = Actual
Open loop
Motor speed is a calculated value (Monitoring variable Motor Speed) showing the load
affect on the speed and slip compensation. Closed loop Motor speed is taken from the
actual encoder signal showing the real speed all the time.
Closed loop
Motor speed is taken from the actual encoder signal showing the real speed all the

P1.13.21
1440
Control slot selector “ControlSlotSel.”
This parameter defines which slot is used as the main control place when two fieldbus
boards have been installed in the drive. When values 6 or 7 are selected, the drive
uses the Fast fieldbus profile. When the Fast fieldbus profile is used, type ‘B’ boards or
other C type boards cannot be used.
0 = All slots
4 = Slot D
