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: FF FE 79 61h to 00 01 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.
