Pulse Test: Analog Output Configuration
The Pulse Test user may config ure two analog output channel s from within the Pulse
Test Wizard.
During the course of the Pu lse Test it is often useful to observe cer tain drive
variables, such as pha se currents (variables Phase A current, Phase B current, and
Phase C current) and line-line voltages (vari ables Output volts, A-B and Output
volts, B-C).
Pulse Test: Bridge Stat e Configuration
During the course of the Pulse Test the power bridge is sequenced between different
states. The sequence is OFF, PARK, PULSE, PARK, PULSE, PARK, OFF. The user
specifies the meanin g of the PARK and PULSE states and the dura tion the sequencer
remains in each of these st ates.
The diagram below shows in a general manner how the Pulse Test switches the
power bridge between th e different states. It also shows h ow current in the bridge
might appear, without in dicating a specific bridge pha se, current direction, or curr ent
magnitude.
