7.5 Common Functions
7 - 65
D
With this setting, the multi-function input pauses acceleration or deceleration and maintains (holds) the
output frequency.
D
Acceleration/deceleration is restarted when the acceleration/deceleration ramp hold input is turned
OFF.
D
The motor will be stopped if a stop command is input while the acceleration/deceleration ramp hold in-
put is ON.
D
When constant d4-01 (the frequency reference hold function selector) is set to 1, the held frequency will
be stored in memory. This stored frequency will be retained even after a power loss and the motor will
be restarted at this frequency when a run command is input again.

Acceleration/Deceleration Ramp Hold
D
When d4-01 is set to 1, the held output frequency will be retained. To operate at this frequency even after
the Inverter is stopped, input the run command with the acceleration/deceleration ramp hold input ON.
D
When d4-01 is set to 0, the output frequency will be held at zero if the run command is input with the
acceleration/deceleration ramp hold input ON.
OH2 Alarm Signal (Setting: B)
OFF
Normal operation
ON
Normal operation (The warning message “OH2” will be displayed on the Digital Operator.)
D
The message “OH2” will be displayed on the Digital Operator while the multi-function input is ON and
the display will revert to its previous status when the input is turned OFF. (It isn’t necessary to reset the
alarm.) The Inverter will continue operation without detecting a fault.
D
With this setting, a temperature sensor can be connected to the multi-function input to display a warning
message when the temperature rises too high.
Multi-function Analog Input Selection (Setting: C)
OFF
Disables the multi-function analog input (terminal 16).
ON
Enables the multi-function analog input (terminal 16).
D
With this setting, the multi-function input can be used to enable or disable the multi-function analog
input.
D
Turning the input OFF has the same effect as setting H3-05 (the multi-function analog input selector
for terminal 42) to 1F.
No V/f Control with PG (Setting: D)
OFF
V/f control with PG feedback (enables speed control with speed feedback)
ON
Normal V/f control (disables speed feedback control.)
D
With this setting, the multi-function input can be used to switch “V/f control with PG feedback” to “Nor-
mal V/f control.” It is possible to switch between these control methods during operation.
