Start
4.
Turn ON the start switch (STF or STR) to apply a voltage across terminals 1 and 5 (4 and 5),
Operation is performed with 130% torque.
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
• If the gain and bias of voltage (current) setting voltage are too close, an error (
• 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 245.)
• Make the bias frequency setting using the calibration parameter C2 (Pr.902) and C5 (Pr.904). (Refer to
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.
