STOP > 20.00 HZ
12.0 INITIAL POWER UP
Before attempting to operate the drive, motor, and driven equipment be sure all
procedures pertaining to installation and wiring have been properly followed.
If input power has not been applied to the drive for a period of time exceeding
three years (due to storage, etc), the electrolytic DC bus capacitors within the
drive can change internally, resulting in excessive leakage current. This can result
in premature failure of the capacitors if the drive is operated after such a long
period of inactivity or storage.
In order to reform the capacitors and prepare the drive for operation after a long
period of inactivity, apply input power to the drive for 8 hours prior to actually
operating the drive/motor system.
Disconnect the driven load from the motor. Verify that the drive input terminals
(L1, L2, and L3) are wired to the proper input voltage per the nameplate rating of
the drive.
Energize the incoming power line. The LCD display should light and flash
“TESTING” and then show the voltage and horsepower rating of the drive. The
display should then show “STOP > 20.00 HZ” which indicates that the drive is in
a STOP condition, and the speed setpoint is 20.00 Hz:
WARNING!
Hazard of electrical shock! Wait three minutes after disconnecting incoming power
before servicing drive. Capacitors retain charge after power is removed.
WARNING!
Severe damage to the drive can result if it is operated after a long period of storage
or inactivity without reforming the DC bus capacitors!
WARNING!
DO NOT connect incoming AC power to output terminals T1, T2, and T3! Do
not cycle input power to the drive more than once every two minutes. Damage to
the drive will result.
