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.
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.
Eliminates problems with resonant vibration of the motor/machine by

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.
Sets the dead-band width around each selected prohibited frequency reference
point.
0: Disabled. Drive starts from zero when the power is switched on.
1: Enabled. At power up, the drive starts the motor at the Hold frequency that
was saved.
Sets the bias added to the frequency reference when the Up 2 and Down 2
digital inputs are enabled (H1-oo = 75, 76).
0: Use selected accel/decel time.
1: Use accel/decel time 4 (C1-07 and C1-08).
Note: The functionality of setting 1 is only accessible via
MEMOBUS/Modbus communication.
