SPDUNT Sets the unit of speed.
0 : Sets the 1 min
-1
unit.
1 : Sets the 10 min
-1
unit.
When a type of motor whose maximum speed exceeds 32767 min
-1
is
used, set this parameter to 1.
The setting of this parameter changes the increment systems of the
parameters listed in the table below.
Parameter No.
