• When P.64=1 and P74=0, the function of external terminal SO is FM function.
The user can insert an electricity meter (current load: 1mA) or a frequency counter between
terminal SO and SE to display the output frequency or the output currency of the inverter.
• When P.54=0 and if the output frequency of the inverter is set as P.55, a pulse of 1440 Hz will be
produced at terminal SO if FM terminal function is selected.
• When P.54=1 and if the output current of the inverter is set as P.56, a pulse of 1440 Hz will be
produced at terminal SO if FM terminal function is selected.
• When P.54=2, the output corresponds to the busbar voltage value. If the voltage between (+/P)-(-/N)
reaches the OV alarm level and the function of external terminal SO is FM function, terminal SO
will output a 1440Hz pulse.
• When P.54=3, the output corresponds to the accumulation rate of temperature increase of the
inverter. If the temperature of the IGBT module of the inverter is too high and reaches the NTC
level, the function of external terminal SO will be FM function and a pulse of 1440Hz will be sent
out.
• When P.54=4, the output corresponds to the electronic thermal rate. If either the electronic thermal
relay (when P.9 ≠ 0) or the electronic thermal relay of the inverter’s IGBT module (when P.9 = 0) is
running, the function of external terminal SO will be FM function, terminal SO will output a
1440Hz pulse.
•When p.54 = 5, the output corresponding to a set frequency.Set the frequency of frequency converter
for p. 55 set value, SO FM function for terminal, terminal SO - SE between the output pulse of
1440 hz
• FM terminal calibration procedures:
1. Insert an electric meter with a full graduation of 1mA or a frequency counter across terminal SO
and terminal SD, and set P.64 to 1, P.54 to 0 and P.74 to 0. Calibrate the header for accessory
variation.
2. Start the motor and fix the output frequency of the inverter to 60 Hz.
3. When the motor runs steadily, read the set value of
P.187
. At this point, the screen will display the
FM correction index. Turn the keyboard knob Clockwise to adjust the value of P.187. The screen
will display a progressively increase of the FM correction index. Press
SET
for more than 0.5
second, and the pointer will move upward. Turn the keyboard knob anticlockwise to adjust the
value of P.187 downward, and the screen will display a progressively decrease of the FM
correction index. Press
SET
for more than 0.5 second and the pointer will move downward.
• When P.64=1 and P.74=1~10, the function of external terminal SO is 10 times the output function.
