INPUT
Operating Mode The “Operating Modes” are: Keypad, Standard Run, 7 Speed, Fan
Pump 2 Wire, Fan Pump 3 Wire, Process Control, 3 Speed Analog 2 Wire, 3 Speed
Analog 3 Wire, EPOT 2Wire, EPOT 3Wire. External connections to the control are
made at the J4 terminal strip (wiring diagrams are shown in Section 3).
ANA CMD Select Selects the external speed reference to be used.
Potentiometer is the simplest method of speed control. Select Potentiometer
and connect a 5K
W
pot at J4-4, J4-5, and J4-6.
0-5 or 0-10VDC input is selected when an input voltage signal is applied to J4-7
and J4-8.
4-20mA or 0-20mA selection should be considered if long distance is required
between the external device and the control. Current loop allows longer
cable lengths at J4-7 and J4-8 with less attenuation of the command signal.
None no external reference is selected.
ANA CMD Inverse “ON” will cause a low input voltage (e.g. 0VDC) to be a maximum
motor speed command and a maximum input voltage (e.g. 10VDC) to be a low
motor speed command.
“OFF” will cause a low input voltage (e.g. 0VDC) to be a low motor speed
command and a maximum input voltage (e.g. 10VDC) to be a maximum motor
speed command.
ANA CMD Offset Provides an offset to the Analog Input to minimize signal drift. For
example, if the minimum speed signal is 1VDC (instead of 0VDC) the ANA CMD
Offset can be set to -10% so the minimum voltage input is seen by the control as
0VDC.
ANA CMD Gain Provides a gain factor for the analog speed reference input signal.
For example, if the analog speed reference signal is 0 - 9VDC, setting the ANA
CMD Gain to 111% allows the control to see 0 - 10VDC as the input signal.
ANA CMD Filter Provides filtering for the analog speed reference input signal. The
greater the number (0 - 6) the more noise filtering is provided. For faster
response, use a smaller number.
OUTPUT
Relay Output N.O. and N.C. relay outputs that may be configured to any of the
following conditions:
Ready Active when power is applied and no faults are present.
Zero Speed Active when output frequency is less than the value of the “Zero SPD
Set Pt” Level 1 Output parameter.
At Speed Band Active when output frequency is within the commanded range
defined by the “At Speed Band” Level 1 Output parameter.
At Set Speed Active when output frequency is at or greater than the “Set Speed
Point” Level 1 Output parameter.
Overload Output is active if the output current is greater than value of the Overload
Set Point parameter value.
Underload Output is active if the output current is less than the value of the
Underload Set Point parameter.
Keypad Control Active when control is in local (keypad) control.
