T-5
= “NEUTRAL” - When the switch is in this position, the control will not drive the motor
in either direction while in manual mode.
= “REVERSE” - When the switch is in this position, the control will drive the motor in
the Reverse direction, while in manual mode and when so permitted. It is also used
to select decrement as the method of adjustment for the program variables.
= “VARIABLE SPEED CONTROL” - By turning the ten (10) turn rotary encoder knob
in a clockwise direction, the motor speed will be increased. When rotated in the
counter-clockwise direction, the motor speed will decrease. The Variable Speed
Control adjustment is normally used to set the manual speed of the motor and the
welding/cutting speed of the motor commanded in an automatic cycle.
= “PRESET CYCLE ENABLED” - Only by depressing the Cycle Push Button
continually for one second, while the control is in “Hold” (Stop) mode, may the preset
cycle routine be toggled from disabled to enabled (as indicated by the constant
illumination of the Auto Cycle Mode L.E.D.). The Cycle Push Button is also used to
increment/decrement the values/settings of the program variables (where
applicable).
= “PRESET CYCLE DISABLED” - Only by depressing the Cycle Push Button
continually for one second, while the control is in “Hold“ (Stop) mode, may the preset
cycle routine be toggled form enabled to disabled (as indicated by the non-
illumination of the Auto Cycle Mode L.E.D.). The Cycle Push Button is also used to
increment/decrement the values/settings of the program variables (where
applicable).
The L.E.D. Display
The control has an L.E.D. display that indicates the travel speed in one of four possible calibration
scales. The calibration scale selection is made using the Motor Control Variables, Rotary Switch,
described later in this manual. The four possible calibration scales are as follows:
1. Calibration in inches per minute (IPM L.E.D. will be illuminated and the closed loop tach
feed back system is required);
2. Calibration in centimetres per minute (CM/MIN L.E.D. will be illuminated and the closed loop
tach feed back system is required);
3. Calibration in other units such as degrees per minute (no L.E.D. will be illuminated and the
closed loop tach feed back system is required, or;
4. Calibration in percentages of full speed obtainable (0 to 100% pulse width duty cycle) (no
L.E.D. will be illuminated and automatically selected when no closed loop tach feed back is
recognized).
Whenever the control is in Stop (hold) mode and there is no Forward or Reverse direction
commanded (Neutral), the speed display will indicate the preset speed.
