An analog input is configured to
fault on signal loss. A signal loss
has occurred.
Configure with [Anlg In 1, 2 Loss]
on
page 3-52 .
1. Check parameters.
2. Check for broken/loose
connections at inputs.
Anlg Cal Chksum 108 The checksum read from the
analog calibration data does not
match the checksum calculated. Replace drive.

to reset a fault and resume
running for the programmed
number of [Flt RstRun Tries].
Enable/Disable with [Fault Config
1] on
page 3-44 .
Correct the cause of the fault and

because it is attempting to limit
bus voltage. 1. Verify input voltage is within drive
specified limits.
2. Verify system ground impedance
follows proper grounding
techniques.
3. Disable bus regulation and/or
add dynamic brake resistor and/
or extend deceleration time.
