(3) Encoder wiring and setting of SW1 on EZJ127 board when used with a dedicated power supply.
●
Wiring used for a dedicated power supply differs according to output interface of the encoder, but can be the same
depending on power supply voltage.
4.3.2-2 Setting to IJ printer
(1) Make the settings related to “Product speed matching” and “Pulse rate div. factor” at the “Print specifications”
screen. (See “4.14 Set the print specifications” in the Instruction Manual.)
●
Set “Product speed matching” to “1: Enable”.
●
Set “Pulse rate div. factor” as required. This function lowers (makes the period longer) the frequency of the
input pulses inside the IJ printer. The divided pulses become the pulses used in printing.
<Description of pulse division function>
●
The rotary encoder signal pulse frequency, the print scan frequency and the division factor have the
relationship shown in (Eq. 1).
Encoder pulse frequency [kHz] =
Print scan count [kHz]
Division factor (l/n)
-
---(Eq. 1)
●
Set “Speed compensation” at the “Print specifications” screen to “Enable”, as required.
<What is “Speed compensation”?>
This function reduces changes in the print start delay when the conveyor speed changes.
This function cannot be used when the product speed matching function is not used.
In addition, this function cannot be used when “Repeat print” mode is set at the “Print specifications”
screen.
When “Speed compensation” is enabled, print start is delayed for 10 scans.
●
Switch setting for a dedicated power supply differs according to power supply voltage, but can be the same
depending on output interface of the encoder.
