Fault / Alarm
A0139
It indicates interruption in the
Offline Profibus communication between the Profibus
DP DP network master and the inverter. The
Interface Profibus DP communication interface
went into offline status.
A0140 It indicates error in the access to the
Profibus DP Profibus DP communication module
Module Access data.
Error
A0163 Analog input signal AIx at 4 to 20 mA or
Signal Fault AIx 20 to 4 mA is below 2 mA.
4..20 mA
A0700
No communication with remote HMI, but
Communication there is no speed command or reference
Fault with for this source.
Remote HMI
A0702
This failure occurs when there is a
Inverter Disabled SoftPLC movement block (REF block)
active and the "General Enable"
command is disabled.
A0704 It occurs when 2 or more SoftPLC
Two Movem. movement blocks (REF Block) are
Enabled enabled at the same time.
A0706
This failure occurs when a SoftPLC
Refer. Not Progr. movement block is enabled and the
SPLC speed reference is not programmed for
the SoftPLC.
A0710 This failure occurs when the user tries
SPLC Progr. to download a SoftPLC program bigger
Bigger than 8 KB than 8 Kb.

Quick Parameter Reference, Faults and Alarms
Description Possible Causes
„
Check if the network master is correctly configured
and operating properly.
„
Check for short-circuit or poor contact on the
communication cables.
„
Check if the cables are not misconnected or inverted.
„
Check if the termination resistors with the right value
were installed only at the end of the main bus.
„
Check the network installation in general – cabling,
grounding.
„
Check if the Profibus DP module is correctly fitted.
„
Hardware errors due to improper handling or
installation of the accessory, for instance, may cause
this error. If possible, carry out tests by replacing the
communication accessory.
„
Current signal on the analog input AIx interrupted
or null.
„
Error in the parameterization of analog input AIx.
„
Check if the communication interface with the HMI is
properly configured in parameter P0312.
„
HMI cable disconnected.
„
Check if the drive General Enable command is active.
„
Check the user's program logic.
„
Check the programming of the references in the
Local and/or Remote mode (P0221 and P0222).
„
Extension of the SoftPLC Prog. exceeded 8 KBytes.
„
Wrong voltage supply; check if the data on the
inverter label comply with the power supply and
parameter P0296.
„
Supply voltage too low, producing voltage on the DC
link below the minimum value (in P0004):
Ud < 200 Vdc in 200-240 Vac (P0296 = 0).
Ud < 360 Vdc in 380-480 Vac (P0296 = 1).
Ud < 500 Vdc in 500-600 Vac (P0296 = 2).
„
Phase fault in the input.
„
Fault in the pre-charge circuit.
„
Wrong voltage supply; check if the data on the
inverter label comply with the power supply and
parameter P0296.
„
Supply voltage is too high, producing voltage on
the DC link above the maximum value (in P0004):
Ud > 410 Vdc in 200-240 Vac (P0296 = 0).
Ud > 810 Vdc in 380-480 Vac (P0296 = 1).
Ud > 1000 Vdc in 500-600 Vac (P0296 = 2).
„
Load inertia is too high or deceleration ramp is
too fast.
„
P0151 or P0153 setting is too high.
