Freq Reference Hold Selection

Sets the function that saves the frequency reference or the frequency bias (Up/Down 2) after a Stop command or when de-energizing the drive.

Set H1-xx [MFDI Function Selection] to one of these values to enable this parameter:

  • A [Accel/Decel Ramp Hold]

  • 10/11 [Up/Down Command]

  • 75/76 [Up/Down 2 Command]

Frequency Ref Bias (Up/Down 2)

Saves the bias value from the Up/Down 2 Command where the Maximum Output Frequency is 100%.

Note:

Parameter A1-02 [Control Method Selection] selects which parameter is the maximum output frequency.

  • A1-02 ≠ 8 [EZOLV]: E1-04 [Maximum Output Frequency]

  • A1-02 = 8: E9-02 [Maximum Speed]

Analog Freq Ref Fluctuate Limit

If the frequency reference changes for more than the level set to this parameter, then the bias value will be held. The value is set as a percentage of the Maximum Output Frequency.
