When parameter 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 interruption and the
motor will be restarted at this frequency when a run command is input again.

Note 1. 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.
Note 2. 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.
Note 3. Select and set one of the following functions for multi-function input. Do not set more than one
of them, otherwise a setting error (OPE3) will result.
S
Acceleration/Deceleration Ramp Hold (Setting: A)
S
UP and DOWN Commands (Settings: 10 and 11)
S
Trim Control Increase and Decrease (Settings: 1C and 1D)
S
Analog Frequency Reference Sample/Hold (Setting: 1E)
D
OH2 Alarm Signal (Setting: B)
OFF
Normal operation
ON
Normal operation (The warning message “OH2” will be displayed on the Digital Operator.)
•
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.
•
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
Terminal 16 Enable (Setting: C)
OFF
Disables the multi-function analog input (terminal 16).
ON
Enables the multi-function analog input (terminal 16).
