Description
Possible cause
Solutions
- wrong parameters values or inadequate
motor.
8
Motor overtemperature The temperature detected by the PTC
thermistor corresponds to a resistance >
2600 ohm.
Reduce the motor load.
Check motor cooling.
9
Reserved (for future
use)
10 CPU error
Loss of data in memory
Call for assistance
11 Parameter default
Execution of reset parameter default
command;
Parameters user setting corrupted
Set parameters again
12 DCbus ripple
Input power supply phase loss, three-phase
power supply unbalance
Check the input power supply phases to the
drive, reduce motor power (speed)
13 Data
communication
fault
Data reception failure
Check the serial connection. Switch the drive
off and back on again.
14 Drive thermistor fault Internal fault
Call for assistance
15 Autotuning fault
Wrong parameter values
Check the parameter values
Restart the command again
16 Driver disabled (STO
input open or de-
energized)
Cable disconnected
Operation of external contactor
24V power supply loss
Check the wiring.
Restore external contactor
17 Motor phase fault (**) Motor cable disconnected
Check the connections of the motor cable
18 Reserved (for future
use)
19 Speed fault
Wrong parameters values or unsuited load Switch the drive off and back on again and
check the parameters are properly set. Check
the motor load.
20 PFC module error
PFC overcurrent
Call for assistance
21 Power
supply
overvoltage
Too high power supply voltage
Check input power supply and if inductive
load generating overvoltage are connected to
the line
22 Power
supply
undervoltage
Too low power supply voltage
Check input power supply
23 STO detection error
Internal fault
Call for assistance
24 Reserved (for future
use)
25 Ground fault
The drive has detected a ground current too
high
Check ground insulation of the motor and
wires .
26 CPU sync error 1
Overload CPU
Call for assistance
27 CPU sync error 2
Loss of data in memory
Call for assistance
28 Drive overload
The current supplied has exceeded the drive
rated current over the maximum time
accepted
Check the load, the dimension of the motor
and the cables. Check the motor parameters.
