Function of Each Parameter
20
UP/DOWN Command Frequency Memory
Selection (n62)
Select whether to store the frequency reference adjusted with
the UP/DOWN function.
Value Description
0 The frequency on hold is not retained.
1 The frequency on hold for 5 s or more is retained.
The UP/DOWN function uses UP and DOWN commands to
change frequency references.
When using the UP/DOWN function, set multi-function input 4
(n39) to 34 (UP or DOWN command). The terminals for multi-
function input 3 (S4) and multi-function input 4 (S5) will be set to
function in the following way:
Multiple-function input 3 (S4): UP command
Multiple-function input 4 (S5): DOWN command
Use n62 (UP/DOWN command frequency memory) to set
whether the frequency reference on hold is stored or not when
an UP or DOWN command is sent to the multi-function input ter-
minals.
If n62 is set to 1, the output frequency held by the UP/DOWN
function for 5 s or more will be stored in the memory. This value
will be stored in memory even if power is interrupted. When a
RESET command is input, operation will start with this value as
the frequency.
If n62 is set to 0, the frequency will be cleared. If parameter init-
ialization is performed (i.e.: n01 is set to 8 or 9), the stored fre-
quency will be initialized.
Note: If the UP/DOWN function is used in remote mode, fre-
quency references can only be given with UP/DOWN
commands and inching commands. Multi-step speed
references will be invalid.
