25.ANALOG OUTPUT #1 MODE SELECT

USE PARAMETER #25 TO SELECT THE SOURCE OF A SIGNAL AT ANALOG OUTPUT #1.

RANGE OF VALUES: 0000 0000h to 0000 0003h

0 to 4 (decimal)

Default Value: 0000 0001h

1 (decimal)

Analog Output #1 may be programmed for several modes of operation. The mode affects where the signal at Analog Output #1 comes from. The following modes are provided for:

0000 0000h

Disabled.

0000 0001h

Actual Speed - Represents the speed

 

of the motor from 0 to parameter #14.

0000 0002h

Load Output - Represents the load on

 

the motor from 0 to 1500.

0000 0003h

Analog Output voltage set by

 

communications from parameters #26

 

and #27.

0000 0004h

Commanded Speed

If an undefined mode (...05h through ...1Fh) is selected, Analog Input #1 will be inoperative.

26.ANALOG OUTPUT #1 LOW ENGINEERING UNITS (EGU)

USE PARAMETER #26 TO SELECT THE THRESHOLD OF ANALOG OUTPUT #1 EFFECT. RANGE OF VALUES: FFFE 7961h to 0001 869Fh

-99,999 to +99,998 (dec.)

Default Value: 0000 0000h

0 (decimal)

Parameter #26 sets the point, in EGU’s, at which the Analog Output #1 will be -10VDC.

27.ANALOG OUTPUT #1 HIGH ENGINEERING UNITS (EGU)

USE PARAMETER #27 TO SELECT THE MAXI- MUM ANALOG OUTPUT #1 EFFECT.

RANGE OF VALUES: FFFE 7961h to 0001 869Fh -99,999 to +99,998 (dec.)

Default Value: 0000 06D6h

1750 (decimal)

If parameter #27 is greater on the absolute scale than #26, voltage at Analog Output #1 will be scaled proportionally from low EGU’s (parameter #26) to +10VDC at the high engineering units (parameter #27).

If #27 is less than #26, then output sense is inverted, i.e., the higher voltage (from -10VDC to +10VDC) will be at the low EGU setting (#26) and the lower voltage will be at the high EGU setting (parameter #27).

28.ANALOG OUTPUT #2 MODE SELECT

USE PARAMETER #28 TO SELECT THE SOURCE OF A SIGNAL AT ANALOG OUTPUT #2.

RANGE OF VALUES: 0000 0000h to 0000 0003h

0 to 4 (decimal)

Default Value: 0000 0000h

0 (decimal)

Analog Output #2 is a general purpose analog output which may be programmed for one of several modes of operation. The mode defines the origin of the signal at Analog Output #2. The following modes are provided for:

0000 0000h

Disabled.

0000 0001h

Actual Speed - Represents the speed

 

of the motor from 0 to parameter #14.

0000 0002h

Load Output - Represents the load on

 

the motor from 0 to 1500.

0000 0003h

Analog Output voltage set by commu-

 

nications from parameters #29 and

 

#30.

0000 0004h

Commanded Speed

If an undefined mode ...05h through ...1Fh is selected, Analog Input #2 will be inoperative.
