    3.8 Multiple Cabinet System Configurations (incl. –MB) Multi-cabinet MX models consist of two or three autonomous or Auxiliary MX15-1Pi units. Auxiliary units do not have their own controller and are identified easily by their blank front panel. Master units each have their own controller but can be configured as auxiliary units by disconnecting the ribbon cable marked J17 between the controller and the system interface board (P/N 7005-701-1).

    3.9 Multiple Cabinet Power Up/Down Procedures For all multi-cabinet MX Series configurations (MX30/2, and MX45/3), the following Power Up (Turn on) and Power Down (Turn off) procedures should be observed. 3.9.1 Power Up Procedure Follow these steps: 1. Turn on each of the Auxiliary units using the front panel circuit breaker, one at a time. The exact order for turning on the auxiliary units is not important.

  • Page 55: Clock And Lock Configurations

    3.10 Clock and Lock Configurations The MX15 Series may optionally be equipped for clock and lock mode of operation. This mode is a special form of Master/Auxiliary, which requires each chassis to have its controller. As such, it is possible to create 1, 2, or 3 phase power systems using 2 to 3 MX15 chassis. For most single- phase configurations, the normal multi-box mode of operation as described in section 3.7.5 is recommended as it provides a single controller (and remote control interface).

  • Page 56: Table 3-12: Clock And Lock Initialization Settings

    3.10.2 Clock/Lock Initialization Settings The mode of operation of the MX15 is determined by the MODE setting in the CONTROL menu. If the clock and lock option is enabled, three choices will be available for this field: STAN, MAST, and AUX. Changing the MODE to either MAST or AUX will cause the power source to power on in clock and lock mode.

    4.2.6 MEASUREMENTS Screens The MX Series uses a DSP based data acquisition system to provide extensive information regarding the output of the source. This data acquisition system digitizes the voltage and current waveforms and calculates several parameters from this digitized data. The results of these calculations are displayed in a series of measurement data screens.

  • Page 77 4.2.7 TRANSIENT Menu The transient menu is used to program and execute user-defined output sequences. These output sequences are defined as a sequential list of voltage and/or current settings that can be executed in a time controlled manner. Each step in these lists is assigned a sequence number ranging from #0 through #99. The numbering determines the order in which each step is executed.

    4.4 Waveform Management [1Pi Controller only] The MX Series with 1Pi controller employs independent arbitrary waveform generators for each phase. This allows the user to create custom waveforms. In addition, three standard waveforms are always available. This chapter covers issues that relate to defining, downloading and managing custom waveforms.

The user can assign a 12-character name to each custom waveform. Avoid using any of the standard waveform names (SINE, SQUARE or CLIPPED) as these names will not be accepted.

  • Page 92: Figure 4-9: Waveform Crest Factor Affects Max. Rms Voltage

    The MX Series power source automatically limits the maximum allowable programmed rms voltage of any custom waveform by calculating the crest factor of the selected waveform and controlling the rms limit accordingly. Thus, each custom waveform may have a different maximum rms value.
  • Page 93 Waveform selection and frequency programming will be subject to the above limit. An error message will be generated to reflect this type of error: "22, Waveform harmonics limit" Transient editing will also generate the above error during keyboard entry. Remote transient entry will not check for the error until transient execution.

    4.5 Standard Measurements Standard measurements are always available through the MEAS key on the front panel. These measurements are spread across two screens to enhance readability. Switching between these screens can be done by successively pressing the MEAS button on the front panel. This will cause the screen to cycle through all available measurement screens.

    loads, measurement inaccuracies on rms and peak current measurements will greatly affect derived measurements such as power, power factor and crest factor. The measurement system on the MX15 Series uses a data acquisition system with a 48 kHz bandwidth. This means that high frequency components of the measured signal are filtered out. Any contribution to the rms value of voltage and current above this cutoff frequency will not be reflected in the MX Series measurements.

    4.7 Transient Programming 4.7.1 Introduction Transient programming provides a precise timing control over output voltage and frequency changes. This mode of operation can be used to test a product for susceptibility to common AC line conditions such as surges, sags, brownouts and spikes. By combining transient programming with custom waveforms [1Pi Controller only], virtually any AC condition can be simulated on the output of the AC source.

  • Page 98: Figure 4-10: Pulse Transients

    4.7.4 Pulse Transients Pulse transients let you program the output to a specified value for a predetermined amount of time. At the end of the Pulse transient, the output voltage returns to its previous value. Parameters required to set up a Pulse transient include the pulse count, pulse period, and pulse duty cycle.

  • Page 99: Figure 4-11: List Transients

    4.7.5 List Transients List transients provide the most versatile means of controlling the output in a specific manner as they allow a series of parameters to be programmed in a timed sequence. The following figure shows a voltage output generated from a list. The output shown represents three different AC voltage pulses (160 volts for 33 milliseconds, 120 volts for 83 milliseconds, and 80 volts for 150 milliseconds) separated by 67 milliseconds, zero volt intervals.

  • Page 100: Figure 4-12: Sample Transient Output Sequence

    Once the dwell time set for a step in the list expires, the next step is entered (if available, if not, execution stops, and the output remains at the final values set in the last step of the list.) Note that while there are parameters for both voltage and frequency level and slew rates, there is only one dwell time, which applies to each step in the transient list.

    4.7.6 Switching Waveforms The FUNCTION field available in each transient list event setup menu may be used to dynamically switch waveforms during transient execution. This allows different waveforms to be used during transient execution. Waveforms may be switched without the output of the source being turned off.

Field Description Setting Range Purpose STA TE Enable the ON/OFF This field allows the regenerative mode of operation to be Regenerate function enabled. The regenerative state can only be enabled if the relay is open and the frequency is set between 40Hz and 80 Hz.
