P0757[2] Value x1 of ADC scaling [V/mA]
Min: 50.0 Def: 0 Max: 150.0
Level 2
Data:
Parameters P0757-P0760 configure the input scaling where:
• 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 10V).
• ASPmin represents lowest analog setpoint (this may be at 0V).
• Default values provide a scaling of 0V=0%, and 10V=100%.

Level 2
Index:
P0758[0] : IN000 Analog input 1 (ADC 1) P0758[1] : IN001 Analog input 2 (ADC 2)
Dependency:
Affects P2000 to P2003 (reference frequency, voltage, current or torque) depending on which setpoint is to be generated.

P0761[2] Width of ADC deadband [V/mA]
Min: 0 Def: 0 Max: 150.0
Level 2
Index:
P0761[0] : IN000 Analog input 1 (ADC 1) P0761[1] : IN001 Analog input 2 (ADC 2)
Note:
P0761[x]=0 : No deadband active.
Deadband starts from 0V to value of P0761, if both values of P0758 and P0760 (y coordinates of ADC scaling) are positive
or negative respectively. However, deadband is active in both directions from point of intersection (x axis with ADC scaling
curve), if sign of P0758 and P0760 are opposite.
Fmin (P1080) should be zero when using center zero setup. There is no hysteresis at the end of the deadband.

P0776 Type of DAC
Min: 0 Def: 1 Max: 1
Level 3
Setting:
0=Current output 1=Voltage output
Note:
The analog output is designed as a current output with a range of 0 to 20 mA. The two analog output channels must be of
the same type, that is, both channels are current outputs with a range of 0 to 20 mA or both channels are defined as
voltage outputs with a range of 0 to 10V.
