The figure and table below show typical KTY84 sensor resistance values as a
function of the motor operating temperature.
The warning and fault limits can be adjusted by parameters.
For the wiring of the sensor, refer to the
Hardware Manual
of the drive.
Motor fan control logic (parameters
…
)
If the motor has an external cooling fan, it is possible to use a drive signal (for
example, running/stopped) to control the starter of the fan via a relay or digital output.
A digital input can be selected for fan feedback. A loss of the feedback signal will
optionally cause a warning or a fault.
Start and stop delays can be defined for the fan. In addition, a feedback delay can be
set to define the time within which feedback must be received after the fan starts.
Automatic fault resets
The drive can automatically reset itself after overcurrent, overvoltage, undervoltage
and external faults. The user can also specify a fault (excluding DIL related faults) to
be reset automatically.
By default, automatic resets are off and must be specifically activated by the user.
WARNING!
Before you activate the function, make sure that no dangerous
situations can occur. The function resets the drive automatically and continues
operation after a fault.
