Parameter Table

8-15

Parameter 579

- [A> DAC Scale 3]

529 - [B> DAC Scale 3]

Use: Scale for for Analog Output 3

Program Terminal Units: None

Minimum Value: –1

Maximum Value: +1

Default Value: +1

Description: This parameter determines the scale factor or Gain for

Analog Output 3. A ± 32767 digital value from the drive is converted to a

± 10V DC signal. Before the digital value is converted the Scale Factor is

applied, thus allowing an effective digital range of ± 2048 (32767/16 =

2048 = 10V DC). This achieved by programming the Scale Factor to

0.0625 or 1/16.

Parameter 580

- [A> DAC Offset 3]

530 - [B> DAC Offset 3]

Use: Offset for Analog Output 3

Program Terminal Units: Volts

Minimum Value: –20 VDC

Maximum Value: +20 VDC

Default Value: 0VDC

Description: This parameter determines the offset applied to the raw

Analog Output 3 value after the Scale Factor is applied. This allows the

User to shift the range of his analog output.

Parameter 581

- [A> DAC Scale 4]

531 - [B> DAC Scale 4]

Use: Scale Factor for Analog Output 4

Program Terminal Units: None

Maximum Value: +1

Minimum Value: –1

Default Value: +1

Description: This parameter determines the scale factor or Gain for

Analog Output 4. A ± 32767 digital value from the Drive is converted to a

± 10V DC signal. Before the digital value is converted the Scale Factor is

applied, thus allowing an effective digital range of ± 2048 (32767/16 =

2048 = 10V DC). This achieved by programming the Scale Factor to

0.0625 or 1/16.
