(T) Multi-Function Input Terminal Parameters
420
PARAMETERS
(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 (CA and 5) does not indicate exactly 60
Hz, set the calibration parameter C0 FM/CA terminal calibration. (Refer to page 375.)
• If the gain and bias of voltage (current) setting voltage are too close, an error ( ) may be displayed at setting.
• Changing C4 (Pr.903) or C7 (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
page 345.)
• Make the bias frequency setting using the calibration parameter C2 (Pr.902) and C5 (Pr.904). (Refer to page 417.)

Operation
1.
Parameter selection
Turn to choose (Pr.125) for the terminal 2, and (Pr.126) for the terminal 4.
Press to show the present set value. (60 Hz)
2.
Torque setting change
Turn to change the set value to " ". (50 Hz)
Press to enter the setting. " " and " ( )" flicker alternately.
3.
Checking the mode/monitor
Press three times to change to the monitor / frequency monitor.
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 4.6.3.)
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.
