Fault Name & Number Fault 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.

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
re ue es
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
ss 2 pu T 2 frequencies.
3. 4-20mA input signal speed reference has been lost or is out
of range and [4-20mA Loss Sel] is set for ‘‘Stop-Fault.”
4. The adapter that was the active frequency source was
disconnected.
loss at 4-20mA input, TB2.
4. Active frequency source cannot be removed.
Hz Sel Fault
F30 Internal error. Reset drive to factory defaults.
