■
Function: DC Bus Voltage (Setting: 7)
The analog output level will correspond to the voltage level of the drive’s DC bus. 100% will correspond to 400 Vdc for the 240 Vac input
iQpump drive and 800 Vdc for the 480 Vac input drive.
■ Function: Output kWatts (Setting: 8)
The analog output level will correspond to an internally calculated output power level based on the measured output current and output
voltage. 100% will correspond to the kilowatt rating of the iQpump drive as determined by o2-04.
■ Function: Term A1 Level (Setting: 15)
The analog output level will correspond to the analog input to the drive’s A1 terminal. 100% will be equivalent to 10 Vdc.
■ Function: Term A2 Level (Setting: 16)
The analog output level will correspond to the analog input to the drive’s A2 terminal. 100% will be equivalent to 10 Vdc.
■ Function: Mot SEC Current (Setting: 18)
The analog output level will correspond to the calculated secondary (torque producing) current. 100% will be equivalent to motor’s full
load secondary current as calculated by:
■ Function: SFS (Softstart) Output (Setting: 20)
The analog output level will correspond to the Speed Command after the applicable acceleration and deceleration rates are applied. The
SFS (Softstart) Output monitor will not include variations to the Speed Command other than the acceleration and deceleration ramps.
100% will be equivalent to the maximum output frequency of the iQpump drive (E1-04).
■
Function: PI Feedback (Setting: 24)
The analog output level will correspond to the analog input to the drive’s A2 terminal during normal PI operation but will correspond to
the A1 analog input when the A2 analog input is configured as a PI Differential input (H3-09 = “16: PI Differential”). The output will
function even if PI operation is not selected (b5-01 = “0: Disabled”). Parameter b5-20 will apply a gain to the measured analog output
voltage before the monitor is displayed.
(i.e. with b5-20 = 5 the 2 Vdc feedback signal will generate 10 Vdc on the analog output).
■
Function: Not Used (Setting: 31)
When H4-01 = “31: Not Used” no voltage is output by the analog output.
■
Function: PI Input (Setting: 36)
The analog output will correspond to the measured error of the PI function. The measured error of normal PI operation is the setpoint
minus the feedback. The measured error of the differential PI is the difference between the A1 and A2 analog inputs summed with the PI
differential setpoint). The output will not function unless PI operation is selected (b5-01
≠0).
■ Function: PI Output (Setting: 37)
The analog output will correspond to the output of the PI function. The PI output will be measured after any gains, offsets, or limits are
applied to the output of the Proportional and Integral factors. The output will not function unless PI operation is selected (b5-01
≠0) and
there is an active Run command. 100% will be equivalent to maximum frequency (E1-04).
■ Function: PI Setpoint (Setting: 38)
The analog output will correspond to the level of the chosen setpoint of the PI function. Please refer to table on page 32 included in the
section PI Control (b5 parameters) for more information about selecting the PI Setpoint source. The output will not function unless PI
operation is selected (b5-01
≠0).
