Clock Option
(contd)
The system uses a 25 millisecond clock to generate encoder pulses.
Conveyor speeds such as 2, 4, 5, 8, 10, 12, 20, 25, 32, 40 and 50 can all
use exactly 1.00 inch resolution. Other speeds require that the encoder
resolution be adjusted to offset the fact that 25 milliseconds may not be an
even multiple of the speed of the conveyor in terms of the number of
milliseconds in an encoder pulse.
Use the following formula to obtain the correct encoder scale to compensate
for the resolution of the internal clock:
Conveyor speed (inches per second) x the next even multiple of 25
milliseconds = encoder resolution.
For example:
1. Convert 18 inches/minute to inches/second: 18 x 12 / 60 = 3.6 ips.
2. Convert to seconds per inch: 1 / 3.6 = 0.277 or 277 milliseconds/inch.
Next highest even multiple period is .3 or 300 milliseconds.
3. Encoder resolution: 0.3 x 3.6 = 1.08.
For example:
1. Convert 50 feet/minute to inches/second: 50 x 12 / 60 = 10 ips.
2. Convert to seconds per inch: 1/10 = 0.100 or 100 milliseconds/inch.
100 is an even multiple of the time period so no additional scaling is
required.
3. Encoder resolution: 0.1 x 10 = 1.00.
