13. (T) Multi-Function Input Terminal Parameters
13.4 Frequency setting voltage (current) bias and gain
Adjustment by changing the frequency without adjusting the voltage (current) (Example of
changing the gain frequency from 60 Hz to 50 Hz)
Operating procedure
1.
Selecting the parameter
Turn the setting dial or press the UP/DOWN key until "P.125" (
Pr.125
) appears for terminal 2, or "P.126" (
Pr.126
)
for terminal 4.
Press the SET key to show the present set value. (60.00 Hz)
2.
Changing the maximum frequency
Turn the setting dial or press the UP/DOWN key to change the value to "50.00". (50.00 Hz)
Press the SET key to confirm the setting. "50.00" blinks.
3.
Selecting the mode and the monitor item
Press the MODE key three times to select the monitor mode and to monitor a frequency.
4.
Start
Turn ON the start switch (STF/STR signal), and turn the frequency setting potentiometer clockwise slowly to full.
(Refer to steps 2 and 3 in
.)
The motor is operated at 50 Hz.
NOTE
• If the frequency meter (display meter) connected to terminal FM or terminal AM of the standard model does not indicate exactly
60 Hz, set the calibration parameter
C0 or C1
.)
• If the voltage (current) values at the gain and bias frequencies are too close to each other, an error "Er3" may be indicated.
• Changing
C4 (Pr.903)
or
C7 (Pr.905)
(gain adjustment) will not change
Pr.20
.
• To set the value to 120 Hz or higher, the
Pr.18 High speed maximum frequency
needs to be 120 Hz or higher. (Refer to
• Use the calibration parameter
C2 (Pr.902)
or
C5 (Pr.904)
to set the bias frequency. (Refer to
Parameters referred to
Pr.1 Maximum frequency, Pr.18 High speed maximum frequency
Pr.20 Acceleration/deceleration reference frequency
Pr.73 Analog input selection, Pr.267 Terminal 4 input selection
Pr.79 Operation mode selection
Pr.858 Terminal 4 function assignment
CAUTION
• Be cautious when setting any value other than "0" as the bias frequency at 0 V (0 mA). Even if a speed command is not
given, simply turning ON the start signal will start the motor at the preset frequency.
