FAULT RECOVERY AND RESETTING THE DRIVE*
(In Automatic Start Mode (Jumper Installed Onto CON1 (Factory Setting))
Fault Drive Recovery
Undervoltage
Drive will automatically start after the bus voltage returns to the
operational level or when the drive is first turned on (power up).
Overvoltage
Drive will automatically start after the bus voltage returns to the
operational level.
Short Circuit After two faults, the drive must be restarted using the AC line.
Motor Overload (I 2 t) Drive must be manually restarted. See Section 13.3, below.
*The fault must be cleared before the drive can be reset.
13.3 RESTARTING THE DRIVE AFTER AN OVERLOAD FAULT HAS
CLEARED
The drive can be restarted after an Overload Fault has cleared by any of the following
two methods.
Note: If an Overload Trip occurs, the motor may be overloaded. Check the motor
current with an AC RMS responding ammeter. Also, the CL setting may be set too
low. See Section 12.6, on page 31.
1. Use the On/Off AC Line Switch to turn the power off and on (approximately
15 seconds). If the cover is opened, observe that the Status LED (ST) changes
from quick flashing red to flashing red/yellow.
2. Set the Forward-Stop-Reverse Switch, if installed, to the "STOP" position and then
to the desired direction setting.
14 DIAGNOSTIC
INDICATORS
The drive contains an illuminated On/Off AC Line Switch and two diagnostic LEDs to
display the drive's operational status. See Figure 2, on page 8, for the location of the
"PWR" and "ST" LEDs.
Note: The drive is factory set to the Automatic Start Mode. For Manual Start/Reset
Mode, see Section 7.3.2, on page 22.
