7. Examine the Status (STS) LED. Verify that it is flashing green or that bit
1 “Sts Ready” of parameter 554 [LED Status] is set when viewed from
the HIM or an application program. If it is not in this state, check the
following possible causes and take the necessary corrective action.
Table 2.B Common Causes of a Run Inhibit
Table 2.C Common Start-Up Faults
If any digital input is configured to Stop - CF (CF=Clear Faults) verify the
signal is present or the drive will not start. Refer to
for a list of
potential digital input conflicts.
If a fault code appears, refer to
The STS LED should be flashing green or bit 1 “Sts Ready” of parameter
554 [LED Status] should be set at this point.
8. Proceed to the “Assisted Start-Up” routine below.
Examine Par 156 - Run Inhibit Status

1
No power is present at the Enable Terminal TB2 - 16
Apply the enable
2, 3, 4 A stop command is being issued
Close all stop inputs
5
Power loss event is in progress, indicating a loss of the AC input voltage Restore AC power
6
Data supplied by the power structure EEprom is invalid or corrupt.
Cycle power. If problem persists, replace the power structure.

8
Drive is expecting a Start Edge and is receiving a continuous signal.
Open all start buttons and remove all start commands
9
Drive is expecting a Jog Edge and is receiving a continuous signal.
Open all jog buttons and remove all jog commands
10
A conflict exists between the Encoder PPR programming (Par 232 or
242) and the encoder configuration for edge counts (Par 233, bits 4 &
5).
Verify encoder data and reprogram
11
The drive cannot precharge because a precharge input is programmed
and no signal is present.
Reprogram the input or close the precharge control contact.

Start input configured but stop not configured
Program Par 825-830 to include a stop button, rewire the drive
Run input configured but control options do not match
Program Par 153, Bit 8 to “0” (2 wire control)
Start input configured but control options do not match
Program Par 153, Bit 8 to “1” (3 wire control)
Multiple inputs configured as Start or Run
Reprogram Par 825-830 so multiple starts, multiple runs or any
combination do not exist
Multiple inputs configured as Jog1
Reprogram Par 825-830 so only (1) is set to Jog1
Multiple inputs configured as Jog2
Reprogram Par 825-830 so only (1) is set to Jog2
Multiple inputs configured as Fwd/Rev
Reprogram Par 825-830 so only (1) is set to Fwd/Rev

Fault
Description
Action
Encoder Loss
One of the following has occurred on an encoder:
• missing encoder (broken wire)
• quadrature error
• phase loss
Reconnect encoder or replace encoder.
Motor Overload
A motor overload is pending.
Enter correct motor nameplate full load amps. Par 2 [Motor NP
FLA] or reduce excess load.
Motor Poles Fault The poles of the motor do not match its rating.
Enter correct motor nameplate information. Par 4 [Motor NP RPM]
