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.
