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.
