90 Program features
Supply phase loss detection (parameter 31.21)
The parameter selects how the drive reacts whenever a supply phase loss is
detected.
Safe torque off detection (parameter 31.22)
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 31.23)
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 31.24...31.28)
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 31.30)
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 49.05)
The parameter selects how the drive reacts to a control panel or PC tool
communication break.
AI supervision (parameters 12.03...12.04)
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.
