Hold Reference Memory Selection (d4-01)
Parameter d4-01 selects whether the held frequency during motor operated potentiometer (MOP) sim-
ulation operation is stored when operation is stopped. MOP operation is enabled by making either of the
following settings for the multi-function inputs (H1-01 to H1-06).
Accel/decel ramp hold (set value: A)
UP command (set value: 10)/DOWN command (set value: 11) {MOP increase/decrease}
When hold status is established by these external signals, specify whether or not the output frequency
is to be retained.
When this function is enabled, operation is re-started after power-up using the frequency reference val-
ue that was retained.
