Fault Messages
Fault Name/Description Corrective Actions
Hardware protection failure
1. Check all connections at L1, L2 and L3.
2. Verify correct voltage at L1, L2,L3.
3. Contact ADC Support for assistance.
Input power has been lost
Check line power to drive
The external terminal EF-CM goes from
OFF to ON
When external terminal EF-CM is closed, the output will be turned
off (under Normally Open. External Fault.).
Auto accel/decel failure
Refer to Over-current or Over-voltage error
1. Possible unbalanced load
2. Possible current leakage
1. Check the motor for possible insulation damage.
2. Check for possible poor insulation at the output line.
AC drive output is turned off.
1. When the external input terminal (base-block) is active, the AC
drive output will be turned off.
2. Disable this connection and the AC drive will begin to work
again.
One phase of the input power is lost
1. Check for possible poor connection on the input power line.
2. Check for possible loss of phase on input power line.
IGBT Short Circuit
Contact ADC Support for assistance.
1. If P 7.27 = 0, (warn and AC drive stop),
PID feedback loss recorded.
2. If P 7.27 = 1, (warn and continue
operation), PID feedback loss not
recorded.
PID Warning:
PID Feedback Loss - The 4-20mA PID signal has been lost.
The corrective action can be set with the PID Feedback Loss
parameter (P 7.27). The available settings are:
00 - Warn and AC Drive Stop
01 - Warn and Continue
The default setting is 00.
