Setpoint source
11 / Frequency setpoint input / Fixed setpoint
The frequency at binary input DI04 specifies the setpoint. Set the value with
the
P102 Frequency scaling
parameter. You can influence the value with
P110 AI1 scaling
. The following parameters are included in the scaling if the
PI controller is activated:
•
P254 PI actual value scaling
•
P255 PI actual value offset
The optimum pulse duty factor (pulse width of the high and low signal)
should be 1 : 1. The factor determines the rising edge and the falling edge
of the input signal. Use P102 Frequency scaling to determine at which input
frequency the system setpoint 100 % is reached. The reference of the sys-
tem setpoint is set via P112 AI1 Operating mode. The direction of rotation is
set via the binary inputs CW/STOP and CCW/STOP.

P302: Maximum speed in rpm
P110: Gain 0.1 ... 1 ... 10
P102: Frequency scaling 1 ... 120 kHz
P112: Operation mode setpoint
Example:
A setpoint generator with the value range 1 ... 50 kHz is to set the motor
speed of 30 ... 1500 rpm.
Set the following parameters for this:
•
P102 Frequency scaling: 50 kHz
•
P112 Operation mode setpoint: 3000 rpm
•
Setpoint scaling P110: 0.5
14 / Bipolar AI2 / Fixed setpoint
The setpoint is provided by the optional analog input AI2 or the fixed
setpoints. The unit processes the fixed setpoints according to their value.
