<- fault initial freq. at 60 Hz

Example 2 The following command sequence performs a frequency step from 60Hz to 62.0Hz, then
ramps down at 1.6Hz/sec to 51.3Hz, and holds this value for 2.3 seconds before changing to a 59.55Hz
postfault value.
Note that, if a stop trigger occurs, the output will change immediately to the postfault frequency value.
VFQ
<- select variable frequency reference mode
VHM1
<- select fundamental
DYN
<- dynamic operation mode for dynamic test
PRF1
<- prefault V&I on
POF1
<- postfault V&I on
FRQ60
<- prefault frequency at 60Hz
FFI62
<- fault initial freq. at 62 Hz
FFF51.3
<- fault final freq. at 51.3 Hz
FRR1.6
<- frequency ramp rate at 1.6 Hz/sec
FDU2.3
<- hold final value for a duration of 2.3 seconds
FPO59.55
<- postfault frequency at 59.55Hz
STR

Example 3 The following command sequence sets the output of all voltages and currents in all fault states
to 400Hz.
VFQ
<- select variable frequency reference mode
VHM7
<- select 7th harmonic
FRQ57.143
<- select base frequency (57.143Hz x 7 = 400.0Hz)
FFI57.143
<- same value for fault state
FPO57.143
and postfault state
Example 4 The following command sequence performs a frequency step from 60Hz to 59.2Hz, then
ramps down to 58Hz at 0.2Hz per second, holds for 60ms, and then returns to 60Hz. Note that, if a stop
trigger occurs, the output will change immediately to the postfault frequency value.
