8.7 Operating Functions - Descriptions and Examples (Cont'd)
Note:
"100% of overload detection level" refers to the value of the inverter's rated
output current.

Application Example - A 3HP 230V G2+ inverter is used to drive a 2HP 230V motor
rated at 6.8 amps full load. Because the inverter is rated at 10 amps there is a danger
of burning up the motor. By using the overload features of the inverter the output
current can be limited and the stall protection level adjusted accordingly.
IV - REFERENCE POINT #1 - Sets the % of the terminal IV input signal which is used
to reference the output frequency designated by F-P1.
#1 OUTPUT FREQUENCY [F-P1] - Sets the output frequency used for reference
point #1.
IV - REFERENCE POINT #2 - Same as reference point #1, except makes reference to
F-P2.
#2 OUTPUT FREQUENCY [F-P2] - Sets the output frequency used for reference
point #2.
SEE SECTION 8.4.2 FOR EXAMPLES.
RR TERMINAL PRIORITY - Activates the terminal into which the analog reference
signal will be input.
JOGGING DRIVE FREQUENCY - Sets the frequency at which the inverter will operate
while in the JOG mode. Used for moving small increments when precise-positioning
of motor-driven equipment is required.
JOGGING STOP CONTROL - Selects between three methods of stopping during a
jog run.
1ST SPEED ~ 7TH SPEED - Sets the frequencies used in the 7 speed run and the
patterned run.
SEE SECTION 8.4.3 FOR DETAILS.
JUMP FREQUENCY POINT #1 AND BAND #1 - Sets the frequency range to be skipped
when running a motor. This function is used when the resonance of the loaded machine
must be avoided. Jump frequency ranges 2 and 3 are also available. See jump frequency
graph on page 8-24.
