MANTA TEST SYSTEMS

VFF#

Voltage - Fault Final

•

Sets the fault final voltage

•

For

-N and 2-

-N fault modes, specify values in volts. Valid values are 0 -

150.00 (volts)

•

For

and 3-

fault modes, specify value in percent. This percentage is the

percentage of the nominal

-N voltage. Valid values are 0-100.0 (%).

•

fault modes, this percentage setting is only approximate.

•

Note that, for 2

-N fault modes, this setting changes the

-N values. However,

the

value is shown on the MTS-1710 display.

VPO#

Voltage - Postfault

•

Sets the postfault voltage

•

For

-N and 2-

-N fault modes, specify values in volts. Valid values are 0 -

150.00 (volts)

•

For

and 3-

fault modes, specify value in percent. This percentage is the

percentage of the nominal

-N voltage. Valid values are 0-100.0 (%).

•

fault modes, this percentage setting is only approximate.

•

Note that postfault must be turned on (using the POF1 command) for this value

to be applied to the outputs in postfault state

•

Note that, for 2

-N fault modes, this setting changes the

-N values. However,

the

value is displayed on the MTS-1710 display.

VDF#

Voltage - Default

•

Sets the default

-N voltage on power-up

•

Valid values are 0 - 150.00 (volts)

•

This value will take effect the next time the MTS-1710 is turned on, or when

default settings are restored. (see Section 5.8.1 for details).

6.2.5.2 EXAMPLES.

The following examples show command sequences using the voltage programming commands:

Example 1 Simple

-N Fault

AVA70

<- set prefault amplitudes to 70V

AVB70
AVC70
PRF1

<- prefault on

POF0

<- postfault off

DYN

<- dynamic operation mode

FMD1

<- simulate B-N fault

VFI15

<- fault amplitude 15V

STR

<- initiate fault

Example 2 Simple

Fault

FMDO

<- simulate A-N fault

AVA70

<- set prefault

-N amplitudes to 70V

AVB70
