Block Title Parameter Description
OUTPUT Continued Analog Output
#1 and #2 Two Analog outputs may be configured so a 0-5VDC (0-10VDC or 4-20mA with High
Resolution EXB) output signal represents one of the following conditions:
Condition Description
Frequency - Represents the output frequency where 0VDC = 0 Hz and +5VDC =
MAX Hz. (Slip frequency compensation is not included.)
Freq Command - Represents the commanded frequency where 0VDC = 0 Hz and
+5VDC = MAX Hz. (Slip frequency compensation is not included.)
AC Current - Represents the value of the output current where 0VDC = 0A and
+5VDC = Level 2, Motor Data, Motor Rated Amps value.
AC Voltage - Represents the value of the output voltage where 0VDC = 0 VAC
and +5VDC = Control Input Voltage.
Torque - Represents load torque where 0V = –100% torque (rated torque),
and +5V = 100% torque (rated torque).
Power - Represents motor power where 0V = –100% rated power, and +5V =
100% rated power.
Bus Voltage - Represents motor power where 0V = 0VDC and 2.5V = 325VDC for
230VAC input (650VDC for 460VAC input).
Process Fdbk - Represents the process feedback input where 0V = –100%
feedback, and +5V = 100% feedback.
Setpoint CMD - Represents Setpoint Command input where 0V = –100% command,
and +5V = 100% command.
Zero Cal - Output is 0VDC and can be used to calibrate an external meter.
100% Cal - Output is 5VDC and can be used to calibrate full scale for an
external meter.
Analog Scale
#1 & #2 - Scale factor for the Analog Output voltage. Useful to set the full scale range for external
meters.
Note: Each analog output can be overscaled. 0V= –100%, 2.5V= 0% and 5V=
100%. The linear equation for this is:
T(%)= 100% x (V – 2.5V)
2.5V
so at 8V, T%=220%. If a value were scaled over the 5V range, 8V would
represent 8/5 x 100%=160%.
Overload SP Motor overload setpoint is set as a percent of peak RMS motor current. If peak RMS
motor current is greater than this preset, a Digital output is set (if programmed). This
option sets an output (Digital Out 1, 2, 3 or 4) when the motor is overloaded.
Underload SP Motor overload setpoint is set as a percent of peak RMS motor current. If peak RMS
motor current is less than this preset, a Digital output is set (if programmed). This option
sets an output (Digital Out 1, 2, 3 or 4) when the motor is underloaded.
