A0046 Motor overload alarm.
Motor overload
A0047
Overload alarm on the power pack with
IGBT overload IGBTs.
A0050
Overtemperature alarm from the power
Power module module temperature sensor (NTC).
overtemperature
A0090 External alarm via DIx (option "Without
External alarm External Alarm" in P0263 to P0270).
A0128 Alarm that indicates serial communication
Telegram reception fault. It indicates the equipment stopped
timeout receiving valid serial telegrams for a
period longer than the setting in P0314.
A0213 Alarm that indicates the short cycle
Protection Against Short protection occurred.
Cycles
A0700 No communication with remote HMI, but
Communication fault with there is no speed command or reference
remote HMI for this source.
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. enabled movement blocks (REF Block) are
enabled at the same time.
A0706 This failure occurs when a SoftPLC
Refer. Not Progr. SPLC movement block is enabled and the
speed reference is not programmed for
the SoftPLC.
A0710 It occurs when you try to download to
SPLC Progr. Bigger than the inverter a SoftPLC Program that is
8 KB too large (larger than 8 KB).

Possible Causes
Settings of P0156, P0157, and P0158 are too low for the
used motor.
Overload on the motor shaft.
Inverter output overcurrent.
High ambient temperature around the inverter (>50 °C (> 122 °F))
and high output current.
Blocked or defective fan.
Heatsink is too dirty, preventing the air flow.
Wiring on DI1 to DI8 inputs are open or have poor contact.
Check network installation, broken cable or fault/poor contact
on the connections with the network, grounding.
Ensure the master always sends telegrams to the equipment
in a time shorter than the setting in P0314.
Disable this function in P0314.
The STAR command occurred during the time count defined
by P0587.
The STOP command occurred during the time count defined
by P0586.
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.
Parameter P0231 or P0236 was not programmed for 5 or 6.
Parameter P0263 or P0264 or P0265 or P0266 was not
programmed for 20.
Main PID controller is enabled (P1017 in 1 or 2) and the
CFW501 frequency inverter is running the motor in LOCAL
mode and parameter P0221 is not programmed for 7.
Main PID controller is enabled (P1017 in 1 or 2) and the
CFW501 frequency inverter is running the motor in REMOTE
mode and parameter P0222 is not programmed for 7.
Parameter P0516 was not programmed for 13 (Hz) or 3 (rpm).
