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

For information regarding the acceleration/deceleration stop (hold) command and the up/down com-
mand, refer to the description of Multi-function Inputs (H1).
J
Trim Control Level: d4-02
D
The trim control level is valid when the trim control increase command (setting: 1C) or trim control de-
crease command (setting: 1D) is set for a multi-function input (H1-01 to H1-06).
D
If the trim control increase command is ON when a frequency reference is input on the analog input,
the trim control level will be added to the analog frequency reference and then output as the output fre-
quency. If the trim control decrease command is ON, the frequency reference will be decreased by the
trim control level.
