Calculate the number of pulses required from the shaft encoder (to within
10%) as follows.
Determine the number of strokes per character "N".
Determine the pitch of the characters "P". This is the distance from the
front edge of one character to the front edge of the next character, in
millimetres.
Determine the distance the product moves in one revolution of the encoder
"D", in millimetres.
Calculate: Required pulses per revolution = D x N
P
Thus, for example:
To print bolderised print, single space (i.e. N = 12), at 3mm character pitch
with the product moving 180mm per revolution of the shaft encoder:
Required shaft encoder output = 180 x 12
3
= 720 pulses per rev.
For final value, multiply the result by the stroke ratio. (see page -10).
Single print, single space = 6
Single print, double space = 7
Bolderise print, single space = 12
Bolderise print, double space = 14
Double bolderise, single space = 24
Double bolderise, double space = 28
16x10 single space = 12
16x10 double space = 14
16x10 bolderise, single space = 24
16x10 bolderise, double space = 28
16x10 double bolderise, single space = 48
16x10 double bolderise, double space = 56
