3-27 Programming
Setpoints (Contʼd)
• If a channel contains no pulses, the ON and OFF setpoints will be “0.”
• If a channel is always on, both the ON and OFF setpoints will be “1.”
Adding a Pulse
You may add a new pulse to a channel by pressing the SEL key when the cursor points
to either the ON or the OFF setpoint.
The display will change to show blank ON and OFF setpoints; the cursor will point to
the ON setpoint. Enter the ON setpoint through the numeric keypad, and then press
the ENT key or the right cursor to move to the OFF setpoint. Enter the OFF setpoint
through the numeric keypad and then press the ENT key.
Adding Multiple Pulses If ON and OFF setpoints for a pulse are visible on the screen and you press SEL to
program a new pulse, the original pulse will remain in the output channel. If the ON or
OFF setpoints entered overlap an existing pulse in the channel, you will see an “Error:
Pulse Overlap” message.
To abort entering a pulse at any time, press ESC.
Changing Setpoints Change a setpoint value with the numeric keys followed by ENT, or with the INC and
DEC keys.
Pulse Modes The Pulse Mode controls how the INC and DEC keys modify setpoints. There are three
modes; EDG (edge), PUL (pulse), and CHN (channel.) Change the Pulse Mode by
pressing the SEL key when the cursor points to the Pulse Mode.
In EDG mode, the INC and DEC keys will affect the selected ON or OFF setpoint only.
In PUL mode, both ON and OFF setpoints will be incremented or decremented simul-
taneously.
In CHN mode, all ON and OFF setpoints for all pulses in the channel will be incremented
or decremented simultaneously.
Deleting a Pulse A pulse may be deleted by making ON equal to OFF, or vice versa. If there is more than
one pulse in the channel, the next pulse will appear in the on/off setpoint area. If the
channel has no more pulses, the ON and OFF setpoint will both be zero.
Clearing a Channel To clear a channel of all pulses, enter a new pulse with ON and OFF setpoints of “0.”
Channel Always ON A channel may be programmed to be on for a full revolution (always on) by entering a
new pulse with both ON and OFF values equal to “1.”
Record Setpoints Photocopy the form inside of the back cover and use it to write down setpoints for each
program.
For most installations, before programming setpoints, it is best to set SHAFT POSITION
to zero at the start of a machine cycle. This allows you to jog the machine to various
points in the machine cycle where output channels must turn on or off, note these ma-
chine positions from the PS-6144 display, and enter them into setpoint programming.
Setpoints programmed in this manner will relate directly to the machine position. If
setpoints are programmed before SHAFT POSITION is set, and SHAFT POSITION
is subsequently changed, the setpoints will no longer correlate with the machine zero
position.
The same logic applies if OFFSET will be used for individual output groups. Program
the offsets before establishing setpoints for the channels in the groups.
CH:1 EDG
ON: 0< OF: 0
ON and OFF setpoints both 0 if no pulses
in channel. Both 1 if channel always ON
CH:1 EDG
ON:---< OF:---
Enter ON setpoint, then ENT or right cursor to OF.
Enter OFF setpoint, then press ENT.
