Sets the Jog frequency reference. Setting units are determined by parameter
o1-03.
Sets the frequency reference upper limit as a percentage of the maximum
output frequency.
Sets the frequency reference lower limit as a percentage of the maximum
output frequency.
Sets the lower limit for frequency references from analog inputs as a
percentage of the maximum output frequency.
Eliminates problems with resonant vibration of the motor/machine by
avoiding continuous operation in predefined frequency ranges. The drive
accelerates and decelerates the motor through the prohibited frequency ranges.
Setting 0.0 disables this function.
Parameters must be set so that d3-01 ≥ d3-02 ≥ d3-03.
