Drive cooling fan
The drive cooling fan is controlled by the temperature from monitoring
points and other actions as follows:
If the "hot" alarm is active or the IGBT temperature (Pr 7.34) is greater
than the upper threshold then the fan will run at full speed. It will continue
to run at full speed until the IGBT temperature is below the lower
threshold. See the table below for the upper and lower thresholds.
Model Upper threshold
DST1201 to DST1204
DST1401 to DST1404
DST1405
If a Solutions Module indicates that it is too hot the fan runs at full speed.
The fan will continue to run at full speed for 10 seconds after the
Solutions Module has cooled down.
The fan can still be forced to run at full speed at all times if Pr 6.45 is set
to one. The fan will continue to run at full speed for 10 seconds after
Pr 6.45 has been set to zero.
For all other conditions the fan runs at low speed.

ACUU AC Supply loss
The drive has detected that the AC supply has been
lost and is attempting to maintain the DC bus voltage
by decelerating the motor.
dc DC applied to the motor
The drive is applying DC injection braking.
dEC Decelerating
The drive is decelerating the motor.
inh
Inhibit
The drive is inhibited and cannot be run.
The drive enable signal is not applied to terminal 31 or
Pr 6.15 is set to 0.
POS Positioning
The drive is positioning/orientating the motor shaft.
rdY Ready
The drive is ready to be run.

Running
The drive is running.
SCAn Scanning
Regen> The drive is enabled and is synchronising to
the line.
StoP Stop or holding zero speed
The drive is holding zero speed.Regen> The drive is
enabled but the AC voltage is too low, or the DC bus
voltage is still rising or falling.
triP Trip condition
The drive has tripped and is no longer controlling the
motor. The trip code appears on the lower display.
