Input Phase Loss; Control Board Temperature; Overfrequency; Internal Fault - ABB ACS800 Firmware Manual

Input phase loss

Input phase loss protection circuits supervise the mains cable connection status by
detecting intermediate circuit ripple. If a phase is lost, the ripple increases. The drive
is stopped and a fault indication is given if the ripple exceeds 13%.

Control board temperature

The drive supervises the control board temperature. A fault indication CTRL B TEMP
is given, if the temperature exceeds 88 °C.

Overfrequency

If the drive output frequency exceeds the preset level, the drive is stopped and a
fault indication is given. The preset level is 50 Hz over the operating range absolute
maximum speed limit (the Direct torque control mode active) or frequency limit
(Scalar control active).

Internal fault

If the drive detects an internal fault, the drive is stopped and a fault indication is
given.

Operation limits

ACS800 has adjustable limits for speed, current (maximum), torque (maximum) and
DC voltage.

Power limit

Power limitation is used to protect the input bridge and the DC intermediate circuit.
If the maximum allowed power is exceeded, the drive torque is automatically limited.
Maximum overload and continuous power limits depend on the drive hardware.
For specific values, refer to the appropriate hardware manual.

Automatic resets

Automatic reset can created with the help of Adaptive Programming (AP), and
