(T) Multi-Function Input Terminal Parameters
406
(c) Adjust only frequency without adjustment of gain voltage (current)
(When changing the gain frequency from 60 Hz to 50 Hz)
NOTE
• If the frequency meter (display meter) connected across the terminals FM and SD does not indicate exactly 60 Hz, set the
Pr.900 FM terminal calibration
. (Refer to
• If the gain and bias of voltage (current) setting voltage are too close, an error (Er3) may be displayed at setting.
• Changing
Pr.903 or Pr.905 (gain adjustment)
will not change
Pr.20
.
Input to the terminal 1 (frequency setting auxiliary input) is added to the frequency setting signal.
• For operation outline of the parameter unit (FR-PU07), refer to the Instruction Manual of the FR-PU07.
• 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
• Make the bias frequency setting using the
Pr.902 and Pr.904
. (Refer to
.)

Operation
1.
Parameter selection
Read
Pr.125
for terminal 2.
Read
Pr.126
for terminal 4.
The present set value is displayed. (60.00 Hz)
2.
Changing the maximum frequency.
Turn
to change the set value to "50.00 Hz".
Press [SET] to enter the setting. "50.00 Hz" is set in
Pr.125 (Pr.126)
.
3.
Checking the mode/monitor
Change the status to the monitor mode.
4.
Start
Turn ON the start switch (STF or STR), then turn the potentiometer (frequency setting potentiometer) clockwise slowly to full.
(Refer to steps 2 and 3 in 4.2.3.)
Operate at 50 Hz.
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.
