Name & Fault Number
Description Action to Take
Diag C Lim FauIt
F36
The drive output current has exceeded the software [Current
Limit] and the [Cur Lim Trip En] parameter was enabled.
Check programming of [Curr Lim Trip En] parameter. Check
for excess load, improper DC boost setting, DC brake volts set
too high or other causes of excess current.
Drive → HIM The checksum read from the HIM’s EEPROM does not match the
checksum calculated from the EEPROM data.
Repeat operation. Replace HIM.
Drive Reset FauIt
F22
Occurs on power-up. Caused by having the Start Input (or Run
Input) closed, with the Stop Input open and [Run On Power Up]
= Disabled.
Check stop connection at TB2, terminal 8.
EEprom Fault
F32
EEPROM has invalid data or can not be programmed to valid
data.
Check cable connection from main control board to power board.
Reset to Default Parameters and Cycle power.
Hz Err Fault
F29
This fault indicates that there is not a valid operating frequency.
It can be caused by any of the following:
1. [Maximum Frequency] is less than [Minimum Freq].
2 Skip frequencies and skip bandwidth eliminate all operating
1. Check [Minimum Freq] and [Maximum Freq] parameters.
2. Check [Skip Freq 1], [Skip Freq 2], [Skip Freq 3] and
[Skip Freq Band] parameters.
3 Check for broken wires loose connections or transducer
