Parameter Table
8-12
Parameter 555 - [A > ADC Offset 3]
505 - [B > ADC Offset 3]
Use: Offset for Analog Input 3
Units: Volts
Minimum Value: –20 VDC
Maximum Value: +20 VDC
Default Value: 0V DC
Description: This parameter determines the offset applied to the raw
Analog Input 3 value before the Scale Factor is applied. This allows the
User to shift the range of the analog input.
Parameter 556 - [A> ADC Scale 4]
506 - [B> ADC Scale 4]
Use: Scale Factor for Analog Input 4
Program Terminal Units: None
Minimum Value: –16
Maximum Value: +16
Default Value: 1
Description: This parameter determines the scale factor or Gain for
Analog Input 4. The parameter has a range of
±
16 with a default value of
1. A
±
10V DC signal applied to Analog Input 4 is converted to a
±
2048
digital value used by the drive. Before the digital value is sent to the drive
the Scale Factor is applied, thus allowing an effective digital range of
±
32767 (16 times 2048). The absolute digital value is clamped at 32767.
Parameter 557 - A> [ADC Offset 4]
507 - B> [ADC Offset 4]
Use: Offset for Analog Input 4
Program Terminal Units: Volts
Maximum Value: +20 VDC
Minimum Value: –20 VDC
Default Value: 0 VDC
Description: This parameter determines the offset applied to the raw
Analog Input 4 value before the Scale Factor is applied. This allows the
User to shift the range of his analog input.
