Alarm Description Possible solutions
A10 IGBT trip alarm The current absorbed by the load in-
stantaneously exceeds the maximum
current protection of the device's power
module.
Reset mode:
• Automatic reset after 10 seconds for
up to 3 attempts, after which you
must wait for 60 minutes.
• Disconnecting the power supply
• Check the possible solutions for alarms A01 Overcurrent motor and
A09 Overload inverter.
• Check for short circuits between the output phases and the ground
insulation.
• Check that the system is properly grounded.
• Check for electrical noise from other devices connected to the sys-
tem.
A11 No load The current absorbed by the load is too
low in relation to the parameter Rated
motor current.
Reset mode:
• Alarm reset by STOP key.
• Disconnecting the power supply
• Check the possible solutions for the alarm A01 Overcurrent motor
A12 Address error In COMBO mode, multiple devices in
the group have the same address.
Reset mode:
• Automatic reset
• Restore the correct value of parameter Address in all the devices in
the group.
• Verify which situation triggers the alarm.
• If the alarm is triggered after a master replacement, check that the
parameter Autorestart is activated.
• Check the electrical connection between the slave unit and the mas-
ter, and the presence of possible disturbances.
A13 No communication In COMBO mode, the communication
between the slave unit and the master
has been interrupted.
Reset mode:
• Automatic reset
• Check the electrical connection between the slave unit and the mas-
ter, and the presence of possible disturbances.
• Exit the master programming menu.
• Attempt a manual reset of the alarm.
CAUTION
Keep signal cables separate and never parallel to
power cables. If it is necessary to cross them, make
sure that they cross perpendicularly.
A14 Min value alarm The value read by the analog input is
lower than the value set for the parame-
ter Min alarm value.
Reset mode:
• Automatic reset
• Check the value set for the parameter.
• Check the hydraulic causes that lead to the alarm condition.
• Check that the sensor is working properly.
A15 Keyboard fault One of the keys of the keyboard was
held down for more than 30 seconds.
Reset mode:
• Alarm reset by STOP key.
• Disconnecting the power supply
• Check that the keys are mechanically free.
A16 CPU alarm Communication error between the con-
trol part and the power part or error in
the CPU.
Reset mode:
• Automatic reset
• Check the value of the power supply voltage both under no load and
load conditions.
• Check for electrical noise from other devices connected to the sys-
tem.
• Check the integrity of the communication cable between the control
board and the power board.
A19 Out of step Loss of motor control
Reset mode:
• Automatic reset with a 3-minute de-
lay.
• Check the possible solutions for the alarm A01 Overcurrent motor
