  • Page 24: Mounting

    Standard model The UC-2000 Universal Laser Controller’s rubber feet are designed for shelf or table-top mounting. If your application requires the UC-2000 to be securely fastened to a shelf or rack, perform the following steps: Remove at least two of the four 6–32 Phillips head screws holding the UC-2000’s rubber feet to the chassis.
  • Page 25: Connecting

    Plug the compact transformer into any 100–240 VAC, 50–60 Hz outlet. For other laser types, power the UC-2000 from any 15–50 VDC source capable of supplying 35 milliamperes (mA) of current. If you choose to supply DC voltage from an alternate power source, ensure that connector polarity to the miniature DC power plug is correct: the tip or inner sleeve polarity is positive (+);...

    PWM duty cycle. The curve of laser output versus PWM duty cycle also varies slightly when different PWM frequencies are used. Press the Lase On/Off pushbutton to halt lasing. The red Lase indicator on the UC-2000 and the laser’s LASE indicator will both turn off.
  • Page 32: Setup

    Setting PWM frequency The UC-2000 sends Pulse Width Modulation (PWM) signals to the laser at user-selectable frequencies of 5, 10, or 20 kHz. The standard modulation frequency of 5 kHz works well in most laser applications and provides the greatest depth of modulation (Figure 3-2 in the Tech- nical Reference chapter).
  • Page 33: Setting Gate Logic

    Gate connector (laser output enabled when gate input is active) causes the UC-2000 to rapidly switch the laser on and off. The laser’s “on” power level is set by the UC-2000’s PWM Adj Knob or by external ANC, ANV, or REMOTE inputs. When laser “off”...

    Enter to exit Setup mode and write operating parameters to memory. Setting lase on power-up Normal operation of the UC-2000 Controller requires an operator to press the Lase On/Off pushbutton to enable lasing after Controller power-up. This safety feature prevents inadver- tent laser operation in the event that power is cycled off and then on again such as during a power failure.
  • Page 35: Setting Remote (Rs-232) Protocol

    This indicates that the new Lase On Power-Up setting is saved into memory. Power down the UC-2000 Controller. The next time the UC-2000 is powered up, the Lase indicator will illuminate and the laser will begin firing immediately at the commanded power setting (provided that the Gate input is active).

    On exit, the Controller beeps twice to indicate that operating parameters were successfully saved to non-volatile memory. Factory default settings Table 2-1 lists factory default settings for the UC-2000 Controller. Table 2-1 Factory default settings...
  • Page 37: Uc-2000 Control

    UC-2000 control You can control the UC-2000 using either of two methods: local control, using panel knobs and buttons; or REMOTE control, using RS-232 serial port commands. Both methods allow you to control laser operation including output power adjustment and On/Off status.
  • Page 38: Remote (Rs-232) Control

    UC-2000 control Autosave feature Six seconds after the last pushbutton or PWM Adj Knob operation (in local UC-2000 con- trol), the Controller automatically saves the current mode settings and PWM power percent- age into non-volatile memory. After saving operational settings, the Controller beeps twice to indicate success.

  • Page 40: Laser Control

    During standby operation (power applied to the UC-2000 Controller with the Lase indicator off), the UC-2000 sends 5 kHz “tickle” pulses to pre-ionize laser gas to just below the lasing threshold. Tickle allows the laser to respond almost instantaneously to Command signals as the beam is switched off and on during laser operations.

    PWM Adj Knob. Rotating the knob changes laser output power from zero to maximum by varying the UC-2000’s PWM output from 0 to 95 (or 99) percent in 0.5% steps. When operating the UC-2000 using REMOTE control, adjust laser power “manually” by sending the appropriate command and data bytes via the RS-232 serial port.

  • Page 46: Control Signals

    Control signals Tickle pulse All SYNRAD lasers require a tickle pulse, a 5 kHz signal with a 1 microsecond (µs) pulse width, which is normally delivered by the UC-2000 Controller. Tickle pulses pre-ionize the laser gas to just below the lasing threshold so that any further increase in pulse width adds enough energy to the plasma to cause laser emission.
  • Page 47: Command Signal

    Base frequency is the repetition rate of the PWM Command signal. The standard base fre- quency is 5 kHz, which has a pulse period of 200 µs. The UC-2000 provides user-selectable PWM frequencies of 5 kHz, 10 kHz (100 µs period), or 20 kHz (50 µs period).
  • Page 48: Table 3-1 Command Signal Output Specifications

    Command signal parameters When operating in MANUAL or MAN. CLOSED mode using local control, set the required PWM Command signal (duty cycle percentage) using the UC-2000’s PWM Adj Knob. When operating in MANUAL or MAN. CLOSED mode using REMOTE control, the PWM Command signal is controlled by a computer or PLC sending PWM or closed loop SET com- mand and data bytes via an RS-232 serial interface.
  • Page 49: External Control

    Each method of external control is described below. Note: All BNC connectors on the UC-2000 are wired so that the signal is connected to the center pin and the signal return, or ground, is connected to the BNC shell.

    Gate connector in order to fire the laser. The UC-2000’s gate input function has two settings: Gate Pull Up (normally on) and Gate Pull Down (normally off). When Gate Pull Up is chosen, UC-2000 circuitry connects an internal resistor to pull the Gate input up to an active level, which means that the laser will fire without a gate signal present when the Lase On/Off pushbutton is pressed.
