3.11.6 TRANSIENTS Menu

Figure 3-17: TRANSIENTS menu

The transient menu provides access to the transient list data. The iM Series does not support
transient programming. The CSW Series has a transient list of up to 100 data points. This is
represented by 100 transient step numbers from 0 through 99. From the Transient menu, the
desired transient step type can be selected. Based on the user’s choice, the relevant transient
type sub menu will be shown. The START/EDIT SEQUENCE sub menu allows the user to
review and change any transient step or execute the transient list. When executing a transient
list, transient steps are executed in a ascending numerical order. Steps that are not defined are
skipped.

The following entries can be found in the TRANSIENTS menu:

Entry

Description

VOLT SURGE/SAG

Voltage surges and sags are temporary changes in amplitude.
The output voltage will change from its present value to a user
specified value for a specified duration. (Sag if the value is
lower, surge if the value is higher.) After this period has expired,
the output voltage returns to a user specified end value. This
value may or may not be the same as the value present prior to
the start of the sag or surge.

VOLT SWEEP/STEP

Voltage sweeps cause the output voltage to change from the
present value to a user specified end value at a specified rate
of change. A voltage step on the other hand is an
instantaneous change in output voltage. The new value will be
held for the duration period specified by the user. The final
output voltage value of a sweep and a step transient step
should be different than the value at the start of the transient
step or no change in output value will occur.

FREQ SWEEP/STEP

This transient type is similar to a voltage sweep/step except it
affects the frequency. Refer to the previous paragraph.

VOLT/FREQ SWEEP/STEP

This transient type combines the previous two types into a
single step. The effect is that of changing the output voltage
and frequency simultaneously.

Note: While this transient is programmed as a single transient
step, two list entries are required to store this information. As
such, every VOLT/FREQ SWEEP/STEP used will consume two
list entries at a time.

START/VIEW SEQUENCE

This entry allows the user to switch to the transient execution
menu. This menu provides a list of all available transient list
steps and their sequence numbers. From this menu, transient
list execution can be started.

The same menu can be used to view or edit any available
transient list step or erase a step using the backspace key.
