POS1R
Return the pointers close to zero position using POS1R
Table 6
Move pointer position at least 24 microsteps CW to the nearest full step position prior to
RTZ.
Check SO to see if Gauge 0 has moved.
- Is bit ST4 logic level 1 If so, Gauge 0 has moved to the first microstep.
Table 12
15
PECR
Send null command to see if gauges have moved.
- Bits PE12
Table 3
Check SO to see if Gauge 0 (Gauge 1) has moved.
- Is bit ST4 (ST5) logic level 1
I
f so, Gauge 0 (Gauge 1) has moved another microstep.
Keep track of movement. If 24 steps are finished and both gauges are at a static
position, then RTZ. Otherwise repeat steps a) and b).
Table 12
16
RTZ
a. Return one gauge at a time to the zero stop using RTZ. Command bit RZ0 selects
the gauge bit RZ1 used to enable or disable an RTZ.
- Bits RZ3:RZ2 are used to select the RTZ accumulator bits clocking out on the SO pin.
Tables 7-8
b. Select the RTZ accumulator bits clocking out on the SO bits ST15:ST8. These will
be used if characterizing the RTZ.
- Bits RZ3:RZ2 are used to select the bits.
17
PECR
a. Check the status of the RTZ by sending the null command to monitor SO bit ST2
- Bit PE12 is the null command.
Table 3
Is ST2 logic level 0 If not, Gauge 0 is still returning. Null command should be resent.
Table 12
18
RTZ
Return theother Gauge to the zerostop. If thesecond gauge is drivinga different pointer
than the first, a new RTZCR command may be required to change the Full Step time.
Tables 7-8
19
PECR
a. Check the Status of the RTZ by sending the null command to monitor SO bit ST3
- Bit PE12 is the null command.
Table 3
Is ST3 logic level 0 If not, Gauge 1 is still returning. Null command should be resent.
Table 12
20
Disable both gauges and go to standby bit PE0:PE1 are used to disable the gauges
Table 3
Put the device to sleep.
- RST pin is pulled to logic 0.
