The following are the possible functions that can be assigned to the four programmable monitors
Value Description Comments
1 Drive compensated output frequency This will be greater than the commanded frequency.
2 Frequency reference This is not necessarily output frequency - drive may be stopped or accel/deceling
3 Output current (output current)2= (torque current)2 + (excitation current)2
4 Input voltage Drive gets from input VAC times 1.73 (will increase during regen).
5 Output voltage
6 Torque current (output current)2= (torque current)2 + (excitation current)2
7 Excitation current (output current)2= (torque current)2 + (excitation current)2
8 PID feedback value Displays the frequency the feedback signal represents
9 Motor OL ratio Example: G3 is rated 150% for 2 min. If you run at 150% for 1 minute, monitor will
10 Inverter OL ratio read “50%”. These monitors represent remaining overload capability. If any monitor
11 DBR OL ratio hits 100%, the drive trips. Drive OL warning starts when drive OL ratio hits 50%
12 Input power In KW
13 Output power In KW
14 RR terminal value Dependent on setting of “RR Input Special Function Select” (1)
15 Peak output current Reset by cycling power, pressing RUN, or resetting drive. Drive keeps track of both
16 Peak input voltage of these values even when not programmed to display as one of the four monitors.
Programming
The following example will make the monitors one through four frequency reference, torque
current, peak input voltage, and peak output current respectively.
Group Parameter New Value

UTILITY PARAMETERS Status Monitor #1 Display Select 6
UTILITY PARAMETERS Status Monitor #1 Display Select 16
UTILITY PARAMETERS Status Monitor #1 Display Select 15
If you want the current values to be displayed as amps, change Current Units Selection in the
UTILITY PARAMETERS group to “1”. If you want the voltage values to be displayed in percent,
change Voltage Units Selection in the UTILITY PARAMETERS group to a “0”.

Setting of RR Input Special
Function Select Comments
1 With 10 volts on ‘RR’ terminal, this monitor shows FH. Effective FH is
displayed as ‘RR’ input is changed. Zero volts on ‘RR’ makes effective
FH 30 Hz.
2 Displays acc/dec multiplier. Zero volts on ‘RR’ results in a display of
“1.0”. Ten volts on ‘RR’ results in a display of “10.0”.
3 Displays effective voltage boost. Zero volts on the ‘RR’ terminal results
in a “0.0” display. At ten volts, Voltage Boost is displayed
4 Displays effective Stall Protection Current Level. Minimum is 10%. A
bug: If Current Units Selection in UTILITY PARAMETERS is set to
show current in amps, no units will be displayed with the value in this
monitor.
