5- Calibration and setting using RS-232 connection
5.1 Zero
Device zero is factory-calibrated. An after-mounting zeroing is preferable in most of
the cases.
Zero can be achieved in two ways:
5.1.1 – using the following RS-232 specific command (via Hyperterminal-like
program):
ZERO
< Enter>
5.1.2 – applying a positive voltage to the “zero-cable” (
brown cable
) for more than 3
seconds and less than 7 seconds.
No LED outputs are available.
Zero is common to both relay function
and
half-axes setting.
5.2 Relay switching point
Relays switching points are factory-set. Factory settings can be modified using RS-
232 communication with any Hyperterminal-like program.
Please refer to the following commands to set intervention ranges:
5.2.1
MDEGX
maximum allowed angle for X axis (related to defined zero).
5.2.2
MDEGX
maximum allowed angle for Y axis (related to defined zero).
Both MDEGX and MDEGY can be set between 0° and 20° abs (absolute value: i.e. if
device is set with zero at 5°, 20°-5° = 15° are left to cover working range).
To set switching angle for X axis using MDEGX command please type desired angle
value multiplied by ten (to allow definition of decimal values of the angle):
MDEGX=40
< Enter>
Sets switching point to 4°.
MDEGX=25
< Enter>
Sets switching point to 2.5°
MDEGX=5
< Enter>
Sets switching point to 0.5°.
