Parameter Function
P0757[0...1] Value x1 of analog input
scaling
P0757 - P0760 configure the input scaling. x1 is the first value of the two pairs of variants x1/y1 and x2/y2
which determine the straight line. The value x2 of analog input scaling P0759 must be greater than the
value x1 of analog input scaling P0757.
Index: See r0752
Notice: Analog setpoints represent a [%] of the normalized frequency in P2000.
•
Analog setpoints may be larger than 100 %.
•
ASPmax represents highest analog setpoint (this may be at 10 V or 20 mA).
•
ASPmin represents lowest analog setpoint (this may be at 0 V or 20 mA).
•
Default values provide a scaling of 0 V or 0 mA = 0 %, and 10 V or 20 mA = 100 %.
•
P0758[0...1] Value y1 of analog input
scaling [%]
Sets value of y1 as described in P0757 (analog input scaling)
Index: See r0752
Dependency: Affects P2000 to P2003 (reference frequency, voltage, current or torque) depending on which setpoint is
to be generated.
P0759[0...1] Value x2 of analog input
scaling
Sets value of x2 as described in P0757 (analog input scaling).
Index: See r0752
Notice: The value x2 of analog input scaling P0759 must be greater than the value x1 of analog input scaling
P0757.
P0760[0...1] Value y2 of analog input
scaling [%]
Sets value of y2 as described in P0757 (analog input scaling).
Index: See r0752
Dependency: See P0758
P0761[0...1] Width of analog input
deadband
Defines width of deadband on analog input.
Example: The following example produces a 2 V to 10 V, 0 Hz to 50 Hz analog input (analog input value 2 V to 10 V,
0 Hz to 50 Hz):
P2000 = 50 Hz
•
P0759 = 8 V P0760 = 75 %
•
P0757 = 2 V P0758 = 0 %
•
P0761 = 2 V
•
P0756 = 0 or 1
•
The following example produces a 0 V to 10 V analog input (-50 Hz to +50 Hz) with center zero and a
"holding point" 0.2 V wide (0.1 V to each side of center, analog input value 0 V to 10 V, -50 Hz to +50 Hz):
P2000 = 50 Hz
•
P0759 = 8.75 V P0760 = 75 %
•
P0757 = 1.25 V P0758 = -75 %
•
P0761 = 0.1 V
•
P0756 = 0 or 1
•
