PHASE FIRE TEST DELTA
(P.309)
The test firing
conduction angle of
the
SCR s. If equal to
0, the armature
power bridge is off. If
it is set to 180, the
armature power
bridge is fully on.
Parameter Range: 0 to 180 DEGREE
Default Setting: 0 DEGREE
Parameter Type: Tunable
OIM Menu Path(s): Current Minor Loop ( CML ) – SCR Diagnostics –
Armature Phase Fire Test.
!
ATTENTION: The armature phase fire test is unregulated. To prevent
excess motor speed, either disconnect the armature leads from the drive
and replace with a similar load or disconnect the field leads from the
drive. Lock the motor armature shaft securely to prevent rotation in either
direction prior to selecting this test. Failure to observe this precaution
could result in severe bodily injury or loss of life.
PHASE FIRE TST BRIDGE (P.310)
Selects which
armature bridge
(forward or reverse) is
used during the
phase fire test. This
input can only be
changed while the
drive is stopped. Parameter Range: ON
OFF
Default Setting: OFF

OFF selects the forward bridge (A1 positive with respect to A2). ON selects the
reverse bridge (A1 negative with respect to A2).
