The motor is operated at 50 Hz.
NOTE
• If the frequency meter (display meter) connected between terminal 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 voltage (current) values at the gain and bias frequencies are too close to each other, an error "
indicated.
• Changing C4 (Pr.903) or C7 (Pr.905) (gain adjustment) will not change Pr.20.
Input to 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 407.)
• Use the calibration parameter C2 (Pr.902) or C5 (Pr.904) to set the bias frequency. (Refer to
