Lamp-test function
The bulbs of pilot lights and illuminated
pushbuttons on the control compartment door (2, 3
and 4 in Figure 96) can be tested with the lamptest
function.
The lamp test is activated via the CDP control panel
by setting parameter 16.7 to lamp test. The lamp-
test function resets itself after a set time.
Status messages
Overview of status messages
The following section lists the messages of the
main operating states of the drive which the drive
passes through: when it is put into operation (see
section Start sequence of the drive), when it is
stopped (see section Stop sequence), or when a
fault condition has occurred. The messages are
sent to the higher-level control system and are
displayed on the CDP control panel of the drive.
For information on other status messages, such as
particular fault status messages, see the status
words of the drive in Appendix M - Signal and
parameter table, located on the CD.
NotReadyOn means that the DC link cannot be
Not ready on
charged and the drive cannot be connected to the
main power supply, i.e. the MV switchgear cannot
be closed. This status message is displayed, for
example, when the doors of medium voltage
compartments are still open, the grounding switch
of the drive is in the grounded position, or the
motor starter of the fan unit is switched off, etc.
See Appendix N - Troubleshooting guide, located
on the CD, for further information.
Ready on
This status message signals that the drive is
healthy and ready for the ON command. The ON
command initiates charging of the DC link
capacitors and closing of the MV switchgear
of the drive. Depending on the control place,
the command can either be sent from the higher-
level control system to the drive or be initiated
by pressing the SUPPLY ON pushbutton on the
control compartment door.
Charging
The status message ReadyOn changes to Charging
when the DC link capacitors of the drive are being
charged.
Ready run
The message ReadyRun tells the operator that the
drive is energized and ready for operation. As soon
as the start command is initiated, the motor is
magnetized and the drive starts to modulate.
Ready ref
When the drive is in ReadyRef state, it is running
and operating according to the set speed or torque
reference value. When in remote control mode, the
reference value is set at the higher-level control
system. When in local control mode, the value is
entered into the CDP control panel.
