Frequency Jump Function (N49 To N51) - Omron SYSDRIVE 3G3JV User Manual

Advanced Operation
• The fault retry function automatically resets and restarts the Inverter in the case the Inverter has an
overvoltage fault, overcurrent fault, or ground fault.
• In the case of any other fault, the protective function operates instantly and the fault retry function does
not operate.
• This function is to be used only if the user does not want to interrupt the mechanical system, even if this
function may damage the Inverter.
• Set n40 for multi-function output to the following value so that external overtorque detection output will
be turned on.
Set value: 14 for fault retries

• The count of fault retries will be cleared in any of the following cases.
The Inverter is normal for 10 minutes continuously after the latest fault retry was made.
Power supply to the Inverter is interrupted.
A fault reset is input.

6-7-5 Frequency Jump Function (n49 to n51)

• The frequency jump function prevents the Inverter from generating frequencies that make the me-
chanical system resonate.
• The frequency jump function can be used effectively to set two dead bands of a frequency reference.
