Start Up 4 - 5
Drive Start Up Procedures
1.
Confirm that all three phases are present and that the input voltage is correct for the Drive being set up.
Measure the voltage on the line side of the Drives Molded Case Circuit Breaker/disconnect and record below.
2.
If voltage level is within Drive Specification (See Appendix C - Specification),
APPLY POWER
to energize the
Drive. The
STOP
,
AUTO SEQ
and
AUTO REF
indicators should be on.
3.
REMOVE POWER
from the Drive. Wait for the Red CHARGE LED (near the power terminals)
to go out.
4.
Connect the motor leads to the Drive at terminals U/T1, V/T2 and W/T3.
5.
APPLY POWER to the Drive.
6.
Press the
HAND
key once. This puts the Drive in the Hand Mode, allowing run/stop and speed commands (frequency
references) by the digital operator. The
AUTO SEQ
and
AUTO
REF
indicators turn off. The
FWD
light turns on.
The
RUN
light turns on. The
STOP
light is blinking. “Frequency Ref” (U1-01) is now displayed on the Digital Oper-
ator.
7.
Press the
OFF
key.
8.
Press the
MENU
key two times. Press the
DATA/ENTER
key once to enter the Quick
Setting Menu
.
Press the
T
key 25 times to display parameter E1-01 “Input Voltage”. This parameter selects the nominal input voltage the Drive
will receive. To set this parameter for the application. Press the
DATA/ENTER
key once. Use the
S
,
T
, and
X
keys
and the
DATA/ENTER
key to set this parameter per the application.

WARNING
Use extreme caution when performing measurements as contact with live parts may result in personal injury
or death.
WARNING
The internal capacitor remains charged even after the power supply is turned off. The status indicator LED’s
and the digital operator display will be extinguished when the DC bus voltage is below 50VDC. To prevent
electric shock, wait at least 5 minutes after all indicators are off and measure the DC Bus voltage level to
confirm a safe level prior to working on the Drive.
