All Modes
Sets the frequency reference upper limit as a percentage of the maximum output frequency.
All Modes
Sets the frequency reference lower limit as a percentage of the maximum output frequency.
All Modes
Sets the lower limit for frequency references from analog inputs as a percentage of the
maximum output frequency.
All Modes
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 not be overlapped.
All Modes
Sets the dead-band width around each selected prohibited frequency reference point.
All Modes
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.
All Modes
Sets the bias added to the frequency reference when the Up 2 and Down 2 digital inputs are
enabled (H1- = 75, 76).
All Modes
0: Use selected accel/decel time.
1: Use accel/decel time 4 (C1-07 and C1-08).
All Modes
0: Bias value is held if no input Up 2 or Down 2 is active.
1: When the Up 2 reference and Down 2 reference are both on or both off, the applied bias
becomes 0. The specified accel/decel times are used for acceleration or deceleration.
All Modes
The Up/Down 2 bias value is saved in d4-06 when the frequency reference is not input by the
digital operator. Set as a percentage of the maximum output frequency.
All Modes
Limits how much the frequency reference is allowed to change while an input terminal set for
Up 2 or Down 2 is enabled. If the frequency reference changes for more than the set value, then
the bias value is held and the drive accelerates or decelerates to the frequency reference. Set as a
percentage of the maximum output frequency.
All Modes
Sets the upper limit for the bias and the value that can be saved in d4-06. Set as a percentage of
the maximum output frequency.
All Modes
Sets the lower limit for the bias and the value that can be saved in d4-06. Set as a percentage of
the maximum output frequency.
All Modes
0: The lower limit is determined by d2-02 or an analog input.
1: The lower limit is determined by d2-02.
