130 PRESET SPEED 7 46 (2.1.21)
These parameters can be used to determine frequency references that are applied when
appropriate combinations of digital inputs are activated.
In Multi-Step Speed Application (Application 4), digital inputs DIN4, DIN5 and DIN6 are
assigned to Preset Speed functions. The combinations of these activated inputs select the
preset speed reference.
NOTE!
The use of TTF-programming method in the Multi-purpose Control Application.
Because all digital inputs are programmable you first have to assign three DINs for
the Preset Speed functions (parameters ID41, ID420 and ID421.

Parameter value is automatically limited to maximum frequency (ID102).
131 I/O FREQUENCY REFERENCE SELECTION, PLACE B3 (2.1.12)
See the values of the parameter ID117 above.
132 PID CONTROLLER D-TIME 57 (2.1.14)
The parameter ID132 defines the derivation time of the PID controller. If this parameter is set
to 1.00 second a change of 10% in the error value during 1.00 s causes the controller output
to change by 10.00%. If the parameter value is set to 0.00 s the PID controller will operate as
PI controller.
