Chapter 5 Commissioning the Drive
Some drive status I/O are active while performing tests in gating test mode. If
monitoring the drive I/O monitored remotely, notify process control in advance
to avoid confusion.
1. From the operator interface screen, press [F10], then ▼
to scroll to
ADVANCED and press [Enter]. Press [F10] to exit this screen.
2. Press SETUP [F8], then [Enter]. The PARAMETERS screen defaults to
Feature Select, the first group listed.
3. Press [Enter] then ▼
to scroll to Operating Mode.
4. Press [Enter] then ▼
to scroll to Gating Test. Press [Enter] to enter gating
test mode.
SCR Firing Test
In normal operation, the SCR firing cards derive their power from a voltage
divider network that steps down the medium voltage to 20 V DC maximum. As
it is necessary to perform this test while isolated from medium voltage, you need a
secondary power source for firing cards.
Each drive has a power cable that supplies 15 V DC from an AC/DC power
supply to the firing cards (SPGDB). This cable has one input you can connect to
an AC source (120/240V, 50/60 Hz) and 18 sets of outputs you can connect to
the SCR self-powered gate driver boards.
ATTENTION: Isolate the drive from medium voltage prior to starting this test.
ATTENTION: Ensure that the drive is no longer running in test mode prior to
applying medium voltage to the drive line-up. Failure to do so may result in
equipment damage.
