The connectable rotary encoder specifications are as stated below.
Output waveform
: Square wave (duty: within 50 ±25%)
Output withstanding voltage : 12 VDC or more
Load current
: 12 mA or more
Leak current
: 0.1 mA or less
Supply voltage
: 12 VDC
Current consumption
: 80 mA or less
(b) Setup
(i) From the print specifications screen, specify whether or not to enable the
product speed matching feature.
(See Section 3.4, Setting Character Height and Character Orientation).
(ii) See the table below and set up switch SW2 on the EZJ95 board (I/O) in
accordance with the rotary encoder output type.
(Switch 2 is inside the cover. Do not operate it unless you have finished the
service education.)
