CENTENT CN0165 MICROSTEP DRIVE
14
OPTION HEADER: RESOLUTION SELECTION
The Option Header selects a microstep
resolution from the eight available in the drive.
The header is located on the face of the drive,
next to the Fault LED.
The jumper configuration for each of the eight
selections is printed on the cover of the
CN0165 adjacent to the Option Header. The
step rate for each selection is shown. To select
a resolution, install the jumper(s) as indicated
for the desired microstep.
Figure 7 - Resolution Header
There are twenty-one different microstep
resolutions available in the CN0165. The
drive is supplied to the user with up to eight
of the twenty-one available. Not all
combinations of step resolutions are possible.
All eight step resolutions for a given CN0165
must come from a single option column (A,
B, C or D) of
X
Table 6
X
.
It is permissible to switch the Option Header
selection dynamically. To accomplish this
the shorting bars are replaced with TTL
compatible drivers. No damage will occur if
the microstep resolution or current profile is
changed while the motor is running.
Switching must occur at the full step location
to maintain accurate step position.
As well as choosing between microstep
resolutions, the Option Header may be used
to select different phase current profiles. Any
combination of microstep resolutions and
phase current profiles may be specified,
provided all step resolutions come from the
same column of
X
