Description
The offset value where the analog speed refer-
ence signal is used is set.
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.
Standard setting: 1000
0 should be set.

0 should be set.
Whether data of the parameters ill to Y20
is valid or invalid is set.
0: Invalid
1: Valid as speed setting unit data
When this parameter is set to 'l", the input
signals to the SF-OR card connector CONC be-
comes valid as data being set to the parameters
