Program features 133
Supply phase loss detection (parameter
The parameter selects how the drive reacts whenever a supply phase loss is
detected.
Safe torque off detection (parameter
The drive monitors the status of the Safe torque off input, and this parameter selects
which indications are given when the signals are lost. (The parameter does not affect
the operation of the Safe torque off function itself). For more information on the Safe
torque off function, see chapter
Planning the electrical installation
, section
Implementing the Safe torque off function
in the
Hardware manual
of the drive.
Swapped supply and motor cabling (parameter
The drive can detect if the supply and motor cables have accidentally been swapped
(for example, if the supply is connected to the motor connection of the drive). The
parameter selects if a fault is generated or not.
Stall protection (parameters
The drive protects the motor in a stall situation. It is possible to adjust the supervision
limits (current, frequency and time) and choose how the drive reacts to a motor stall
condition.
Overspeed protection (parameter
)
The user can set overspeed limits by specifying a margin that is added to the
currently-used maximum and minimum speed limits.
Local control loss detection (parameter
The parameter selects how the drive reacts to a control panel or PC tool
communication break.
AI supervision (parameters
…
The parameters select how the drive reacts when an analog input signal moves out of
the minimum and/or maximum limits specified for the input. This can be due to broken
I/O wiring or sensor.
Automatic fault resets
The drive can automatically reset itself after overcurrent, overvoltage, undervoltage
and external faults. The user can also specify a fault that is automatically reset.
By default, automatic resets are off and must be specifically activated by the user.
