5.4.14 Parameter copy alarm release
The parameter copy alarm can be canceled. The parameter copy alarm is generated when parameter copy is performed
between the FR-F860-00680 or lower and the FR-F860-01080 or higher.
*1 The setting range or initial value for the FR-F860-00680 or lower.
*2 The setting range or initial value for the FR-F860-01080 or higher.
• The setting range of some parameters differ between the FR-F860-00680 or lower and the FR-F860-01080 or higher.
When parameter copy is performed between the FR-F860-00680 or lower and the FR-F860-01080 or higher, the
parameter copy alarm (CP) is displayed on the operation panel because resetting of some parameters is necessary.
• Use Pr.989 to cancel the parameter copy alarm. After setting Pr.989, perform setting of Pr.9, Pr.30, Pr.51, Pr.56, Pr.57,
Pr.61, Pr.70, Pr.72, Pr.80, Pr.82, Pr.90 to Pr.94, Pr.453, Pr.455, Pr.458 to Pr.462, Pr.557, Pr.859, Pr.860, and Pr.893
again.
5.4.15 PWM carrier frequency and Soft-PWM control
The motor sound can be changed.
*1 The setting range for the FR-F860-00680 or lower.
*2 The setting range for the FR-F860-01080 or higher.
Changing the PWM carrier frequency (Pr.72)
• The PWM carrier frequency of the inverter can be changed.
• Changing the PWM carrier frequency can be effective for avoiding the resonance frequency of the mechanical system or
motor, as a countermeasure against EMI generated from the inverter, or for reducing leakage current caused by PWM
switching.
