Frequency setpoint via analog input (AI) (P1000 = 2)
Parameter Description (Parameter name and factory setting (if not variable) in bold) Setting
P0756 = 0 AI type
Defines the type of the analog input and also enables analog input monitoring.
0: Unipolar voltage input (0 to +10 V)
1: Unipolar voltage input with monitoring (0 V … +10 V)
2: Unipolar current input (0 mA … 20 mA)
3: Unipolar current input with monitoring (0 mA … 20 mA)
4: Bipolar voltage input (-10 V … +10 V)
NOTE: The following applies for P0756 … P0760:
Index 0: Analog input 0 (AI0), terminals 3 and 4
Index 1: Analog input 1 (AI1), terminals 10 and 11
P0757 = 0 Value x1 of AI scaling [V/mA]
P0758 = 0.0 Value y1 of AI scaling
this parameter represents the value of x1 as a
percentage of P2000 (reference frequency)
P0759 = 10 Value x2 of AI scaling [V/mA]
P0760 = 100 Value y2 of AI scaling
This parameter represents the value of x2 as
a percentage of P2000 (reference frequency)
