Table 5-5 shows X5 keypad warning messages that may appear during operation:
Reverse
The drive is running in reverse without accelerating, decelerating or residing at the reference
frequency. This means that something is keeping the drive from the reference frequency (for
example, Current Limit).
Not Enabled
The drive is not allowed to run either because the digital input enable is not active or because
ARCTIC mode has shut down the run operation.
Volt Range
The drive has not met the input voltage voltage requirements that it needs to be able to run. In other
words, the Bus Voltage of the drive is either too low or too high.
Low Voltage The drive has reached an undervoltage state.
Kpd Stop
A stop command was given from the keypad when the keypad was not the active control source. To
remove this condition, the run signal to the drive must be removed.
TOD Inhibit
The drive is not enabled because of time restrictions programmed into the Time of Day parameters.

Message
Meaning
DB Active
The DB Resistor is being actively pulsed.
Curr Limit
The drive is operating in current limit.
HS Fan Err
Either the heatsink fan should be on and is off, or vice-versa.
Addr XXX
This is the node address of the drive when it receives a valid message through the IR port
address to another node. The XXX will be replaced with the node address.
High Temp
The temperature of either the heatsink or the control board is nearing a high temperature limit
that will fault the drive.
Low Temp
The temperature of either the heatsink or the control board is nearing a low temperature limit that
will fault the drive.
Vac Imblnce
Either the drive has lost an input phase or the input voltage is unbalanced more than 2%.
Power Supp
A power supply short occurred.
Seq Dwell
The sequencer is active, but the transition to the next step is halted.
Int Fan Err
Either the internal fan is on and should be off, or vice-versa.
DB OverTemp
The temperature of the DB Resistor is nearing a high temperature and will fault the drive.
ARCTIC Mode
The ARCTIC DB Resistor mode is actively pulsing the DB Resistor.
CPU Warning
A system error occurred in the software of the X5.
Mtr Measure
An RS Measurement is armed or active.
IR Active
Valid IR communications are occurring.
Seq Running
The program sequencer functionality is active.
Clock Error
The clock does not have the proper time programmed into it, or there is a problem communicating
with the RTC chip.
Battery Low
The drive has detected that the RTC chip’s battery is getting low.
Op BD Found
The drive has detected that an option board is now connected.
