REMOTE REV OUT
PREF: 92.23

Range: FALSE / TRUE
This parameter indicates the current state of remote direction and RUN REVERSE. Note - this is the demanded direction, not
the actual direction.
HEALTHY
PREF: 92.24
Default: TRUE
Range: FALSE / TRUE
Set FALSE when the Drive trips, and set TRUE when the run command is removed.
FAN RUNNING
PREF: 92.26
Default: FALSE
Range: FALSE / TRUE
This can be used to control the running of externally supplied fans. TRUE when the drive heatsink is hot, when the ambient
temperature is high or when the motor load is high. Remains TRUE for 60s after the load o
r temperature has dropped.
Initialised TRUE on frame size B following a power on.
CONTACTOR DELAY
PREF: 92.27
Default: 10.0 s
Range: 1.0 to 10 s
On entry to the SWITCHED ON state the sequencing logic sets the OUTPUT CONTACTOR output to TRUE and starts an
internal delay timer. The logic then waits for the feedback signal CONTACTOR CLOSED to be TRUE before moving on to
the READY state. If the CONTACTOR CLOSED signal does not go TRUE within the delay time set by CONTACTOR
DELAY then the drive will trip with
a CONTACTOR FBK trip.
