D4: Frequency Ref Up/Down & Hold - YASKAWA GA800 Programming Manual

2.5 d: References
Note:
• When you set Jump Frequencies 1 to 3, make sure that the parameters do not overlap.
• When the drive is in the range of the Jump frequency, the frequency reference changes automatically. When Jump is executed, the output
frequency changes smoothly as specified by the values set in C1-01 [Acceleration Time 1] and C1-02 [Deceleration Time 1].

d4: Frequency Ref Up/Down & Hold
The d4 parameters set the Frequency Reference Hold function and Up/Down and Up/Down 2 commands.
• Frequency Reference Hold Function Command: This acceleration/deceleration ramp hold command uses an MFDI
to momentarily stop the acceleration/deceleration of the motor, and continues to operate the motor at the output
frequency at which the command reference was input. Turn OFF the acceleration/deceleration ramp hold command
to continue acceleration/deceleration.
• Up/Down command: The Up/Down command is a function to activate and deactivate an MFDI to increase and
decrease the frequency reference. The Up/Down command overrides frequency references from the analog input
terminal, pulse train input terminal, and keypad.
• Up/Down 2 command: The Up/Down 2 command is a function that adds a set bias value to the frequency reference
to accelerate or decelerate. The Up/Down 2 command activates and deactivates the MFDI to add a bias value.
