Use the
SC
operator to assign the drive status bits to a binary variable (
VARB
) or to make a comparison against
a binary or hexadecimal value. To make a comparison against a binary value, the letter b (b or B) must be
placed in front of the value. The binary value itself must only contain ones, zeros, or Xs (1, 0, X, x). To make
a comparison against a hexadecimal value, the letter h (h or H) must be placed in front of the value. The
hexadecimal value itself must only contain the letters A through F, or the numbers 0 through 9.
Syntax:
VARBn=SC
where “
n
” is the binary variable number, or
SC
can be used in an expression such as
IF(SC=b0010)
, or
IF(SC=h7F)
. If it is desired to assign only one bit of the drive status value to
a binary variable, instead of all 32, the bit select (
.
) operator can be used. For example,
VARB1=SC.3
assigns drive status bit #3 to binary variable 1:
*VARB1=XX0X_XXXX_XXXX_XXXX_XXXX_XXXX_XXX_XXXX
.
The function of each drive status bit is shown below.

NOTE : All scaling settings (
SCALE
,
SCLA
,
SCLD
,
SCLV
and
SCLMAS
) are
automatically saved in the Gem6K’s battery-backed RAM.
Scaling allows you to program acceleration, deceleration, velocity, and position values in units of measure
that are appropriate for your application. The
SCALE
command is used to enable or disable scaling (
SCALE1
to enable,
SCALEØ
to disable). When scaling is enabled (
SCALE1
), all entered data is multiplied by the
appropriate scale factor:
Type of Motion Accel/Decel Scaling Velocity Scaling Distance Scaling
Standard Point-to-Point Motion SCLA SCLV SCLD
Following SCLA SCLV
SCLD
for follower distances
SCLMAS
for master distances
