ATTENTION: In the following steps the motor will begin to
rotate. It is possible that the motor will rotate at an uncontrolled
rate or cause incorrect machine movement. Be prepared to
remove drive power by opening the branch circuit disconnect
device if this occurs. Incorrect movement may be due to a
wiring/programming error or system component malfunction
and must be corrected before proceeding with this procedure.
Damage to machine system components can occur due to
uncontrolled machine movements.
It is recommended that the motor be mechanically disconnected
from the load if:
A) Improper direction of rotation could cause damage to
equipment.
B) Uncontrolled motor rotation due to improper phasing will
cause damage to the equipment.

o 9. Apply 24V DC to the Coast to Stop and Drive Enable inputs
(Forward Run, Reverse Run and Orient Command must be Off).
After about 5-7 seconds, the main contactor will close and the Drive
Ready output will turn On. In addition, the letter “G” should appear
on the DIAGNOSTICS – I/O Output display. If the main contactor
does not close and the Hard Fault output is still On, verify that the
two wire cable is attached to connector J3 in the lower left corner of
the I/O Board. This cable provides the hard wired connection of the
Coast to Stop input to the main AC contactor control circuit. If it is
not connected, the contactor can not be closed.
o 10. Apply 24V DC to either the Forward Run or Reverse Run inputs.
The drive will now run in Spindle Mode at Acc Rate # 1. Depending
on configuration programming, either an analog speed command on
Analog Input # 1 or a digital speed command from the optional
digital command inputs will be used.
o 11. If the motor does not turn, runs only at a slow speed, or slowly
oscillates forward and reverse, the motor phasing must be reversed.
Remove the Run and Drive Enable inputs.
Important: Before changing any parameters in response to
observed drive operation, always verify that the gear range indicator
number shown in the first position of each line on the display is the
same. If they are not, use the GEAR RANGES – Select Range
parameter to change the number on the second line to match the
number on the first line of the display.
Change the setting of the PARAMETER SET – ELECT CONFIG –
Motor Phasing parameter to reverse the motor phasing without
physically changing the wiring to the motor. Reapply the Drive
Enable and Run inputs and check for correct operation.
