Fig 7.35 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 warn-
ing 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 16) 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
“Normal V/f control.” It is possible to switch between these control methods during operation.
Speed Control Integral Reset (Setting: E)
OFF
Operates with PI-control speed control loop.
ON
Operates with P-control speed control loop. (The speed control integral values are reset by the
integral time constant.)
D
This function is valid only for V/f control with PG feedback when constant F1-07 is set to 0. (Setting
F1-07 to 0 disables integral operation during acceleration/deceleration.)
D
It is possible to switch between these speed control modes during operation.
