Analog Inputs and Outputs
Analog Inputs
Two analog inputs are available: analog input #1 (J1A-1 and J1A-2) and analog input #2
(J1A-4 and J1A-5) as shown in Figure 3-15. Either analog input #1 or #2 may be
grounded provided the common mode range is not exceeded. Either analog input may
be selected in the Level 1 INPUT block, COMMAND SELECT parameter value. Analog
input #1 is selected if parameter value “POTENTIOMETER” is selected. Analog input #2
is selected if parameter value “+/–10Volts, +/–5 Volts or 4-20mA” is selected. Only one
analog input can be used but either may be selected.

Analog Input #1
The single ended analog input #1 is used when the control is set to Standard 3 Wire
Mode. When using a potentiometer as the command input, the Level 1 Input block
COMMAND SELECT parameter must be set to “POTENTIOMETER”.
1.
Connect the wires from the 5K
W
pot as shown in Figure 3-15. One end of the
pot is connected to J1A-1 (analog ground) and the other end is connected to
J1A-3 (Pot Reference).
2.
Connect the wiper of the pot to J1A-2. The voltage across terminals J1A-1 and
J1A-2 is the speed command input.
3.
A 0-10VDC speed command signal may be connected across J1A-1 and J1A-2
instead of a 5K
W
pot.
Analog Input #2
Analog input #2 accepts a differential command
±
5VDC,
±
10VDC or 4-20 mA. The
operating mode is defined in the of the Level 1 Input block COMMAND SELECT
parameter.
Note: Analog Input #2 is used with Standard Run 3-Wire or Bipolar Control modes
and not used for the 15 Speed 2 Wire mode.
1.
Connect the Analog Input 2(+) wire to J1A-4 and the 2(–) wire to J1A-5.
2.
JP1 must be properly set for either voltage or current operation. Refer to
Figure 3-16 for jumper information.
Note: Analog Input #2 can be connected for single ended operation by grounding
either of the inputs, provided the common mode voltage range is not
exceeded. The common mode voltage can be measured with a voltmeter.
Apply the maximum command voltage to analog input 2 (J1A-4, 5). Measure
the AC and DC voltage across J1A-1 to J1A-4. Add the AC and DC readings
together. Measure the AC and DC voltage from J1A-1 to J1A-5. Add the AC
and DC readings together.
If either of these measurement totals exceeds a total of
±
15 volts, then the
common mode voltage range has been exceeded. If the common mode
voltage range has been exceeded, the solution is either to change the
command voltage source or isolate the command voltage with a commercially
available signal isolator.
