Description
The offset value where the analog speed refer-
ence signal is used is set.
Generally, it is
adjusted using the offset variable resistor
on the NC.
Standard setting: 0

Not used. 0 should be set.
The gain against the speed reference signal
is set. Assume that 1000 is 1 unit, the
real speed reference signal is made by multi-
plying the set data by the external speed
reference signal.
Generally,
it si adjusted by the gain volume
of the NC.

The speed
reference which is selected by the speed selec-

The data is
set by the motor speed in such a manner that it
does not exceed the motor maximum speed which
is set by
TSP.
