Display Operation
The remote display receives data from the PL
µ
S control via
RS-485 serial communication. NOTE: Prior to date code
9740, the “-E” and “-C” options were required for
communications. The display will show either the
controller's present rotary position or RPM as follows:
P 3 5 9 (example of position 359 shown by remote display)
r 2 5 0 (example of 250 RPM shown by remote display)
The toggle RPM (“tr”) value programmed in FCN 0
determines the speed at which the display switches from
showing position to RPM. At speeds below the toggle RPM
value, position will be shown. At speeds equal to or above
toggle RPM, the current RPM value will be displayed. It is
not necessary for the control's display default (“dd”) to be
set to auto; the display will automatically switch between
position and RPM at the toggle RPM value, regardless of
what the control's display is showing. The value of RPM
update (“ru”) will determine how many times per second the
display updates RPM.
To display position at all times, set the toggle RPM to a
number that is higher than the maximum speed of the
machine. To display RPM at all times set the toggle RPM
to zero.
Note: A jumper between term 4 & 6 on the PL
µ
S comm port
will disable display data to allow normal serial
communication.
Controller / Display Setup
Controller
Setup these FCN 0 items in the PL
µ
S control as follows:
cS = 9600 9600 baud selected for communication speed.
This is the fastest speed at which the display
will operate, and is the factory default speed
for the controller.
ct = 485 RS-485 format selected for serial port. Display
data will not be transmitted by the controller
when in the RS-232 mode.
tr = ? Select the RPM value where display switches
from showing position to RPM
Display
All of the programmable items in the display will be correctly
set at Electro Cam before the display is shipped. This
information is stored in permanent memory in the display
and should never have to be programmed. However, if the
display does not operate when connected to the control,
check for correct display settings as follows:
1. Press SW1 & SW2 simultaneously until the message
“b_rate” is displayed for one second. The current baud
rate will appear.
2. If the current baud rate is 9600, go to Step 3. Otherwise,
press SW3 until 9600 is displayed.
3. Press SW1 to store the 9600 baud rate and return to
normal operation.
