A136 Alarm indicates that the DeviceNet
Idle Master network master is in Idle mode.
A137 Alarm that indicates that one or more
DeviceNet DeviceNet connections timed out.
Connection
Timeout
A163 Analog input signal AI1 at 4 to 20 mA or
Signal Fault AI1 20 to 4 mA is below 4-20 mA.
A700 No communication with remote HMI,
Remote HMI but here is frequency command or
Communication reference for this source.
Fault
A702 This failure occurs when there is a
Inverter Disabled SoftPLC movement block (REF block)
active and the "General Enable"
command is disabled.
A704 It occurs when 2 or more SoftPLC
Two Movem. movement blocks (REF Block) are
Enabled enabled at the same time.
A706 This failure occurs when a SoftPLC
Refer. Nao Progr. movement block is enabled and the
SPLC speed reference is not programmed for
the SoftPLC.
A712 It occurs when there is an attempt to
SPLC protected copy the SoftPLC application protected
against copy against copies.

Quick Reference of Parameters, Alarms and Faults
Description Possible Causes
„
Set the switch that controls the master operation
of the master for Run or the corresponding bit on
the configuration word of the master software.
If further information is needed, refer to the
documentation of the master used.
„
Check the network master status.
„
Check network installation, broken cable or
fault/poor contact on the connections with
the network.
„
Cable of AI1 broken.
„ Poor contact at the signal connection on the
terminals.
„
Check if the communication interface with the
HMI is properly configured in parameter P312.
„
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 (P221 and P222).
„ Attempt to copy WLP application protected
against copies ("never permit copies").
„
Attempt to copy WLP from a copy protected
against copies ("no permission to copy from
a copy")
„
Wrong voltage supply; check if the data on the
inverter label comply with the power supply and
parameter P296.
„
Supply voltage too low, producing voltage on
the DC link below the minimum value (in P004):
Ud < 200 Vdc in 200 / 240 Vac.
„ Phase fault in the input.
„
Fault in the pre-charge circuit.
