Hold Reference Memory Selection: d4-01

J
Constant d4-01 is enabled by making either of the following settings for the multi-function inputs
D
(H1-01 to H1-06).
Acceleration/deceleration ramp hold (setting: A)
•
Up command (setting: 10)/down command (setting: 11)
•
When hold status is established by these external signals, specify whether or not the output frequency
D
is to be retained.
When this function is enabled, operation is re-started after power-up using the frequency reference val-
D
ue that was retained.

Trim Control Level: d4-02

J
The trim control level is valid when the trim control increase command (setting: 1C) or trim control
D
decrease command (setting: 1D) is set for a multi-function input (H1-01 to H1-06).
If the trim control increase command is ON when a frequency reference is input on the analog input,
D
the trim control level will be added to the analog frequency reference and then output as the output
frequency. If the trim control decrease command is ON, the frequency reference will be decreased by
the trim control level.
