Inverter status
Diagnostic Parameters
Description
Electronic Motor Overload protection
was activated.
This message indicates that serial
c o m m u n i c a t i o n b e t w e e n t h e
keypad operator and the drive or
the drive and the elevator control
has been lost. See parameter
US.2 to bypass this fault.
This message precedes most faults
and also occurs if the drive enable is
turned off while the car is running.
This indicates the power stage is not
ready for operation.
Normal Operating Messages
Display Significance
No Operation, terminal X2.1 (Drive Enable) is not set
noP
Low speed, inverter is enabled but no direction of
LS
rotation is set, motor current still off
Forward acceleration
Facc
Forward constant running
Fcon
Forward deceleration
FdEc
Reverse acceleration
rAcc
rCon Reverse constant running
rdEc Reverse deceleration
boff Indicates brake should be in the process of releasing
at beginning of run
bon Indicates brake should be setting at end of run
Cause and Solution
• Excessive motor current above the
value adjusted in LF. for IM or LF. and
LF.12 for PM motors.
• Look for mechanical loading problems
or motor data adjustment in parameters
LF.10...LF.1.
• If communication is restored this fault
will clear after 4 seconds. If not remove
the operator, cycle power to the drive,
verify the red pilot LED on the control
board of the drive turns on and stay on,
(not flashing), and then install operator
again.
• When using serial communication with
the elevator controller, make sure the
serial cable to the controller is plugged
into X6C on the operator. Also refer to
parameter LF.2 part "e" for more info on
clearing E.BUS faults in this case.
• Indicates the output transistors have
been safely shut off and are being
blocked from further operation.
• Typically the result of a hardware failure.
Replace the drive.
