Drive temperature

The drive supervises the IGBT temperature. There are two supervision limits: Alarm
limit and fault trip limit.

Short circuit

If a short circuit occurs, the drive will not start and a fault indication is given.

Internal fault

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

Operation limits

The drive 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, see chapter

Automatic resets

The drive can automatically reset itself after overcurrent, overvoltage, undervoltage,
external and "analog input below a minimum" faults. The Automatic Resets must be
activated by the user.
