Description
F32-Kinetic backup
DC link voltage falled under KB setpoint [753] (page 72), the correction affects the
ramp output. Only if Kinetic backup is turned on ( Kinetic backup (KB) [748] (page
72)). For the duration of the warning, the value of Voltage DC [46] (page 16) is
displayed in FAULTS window.
W33-Quick STOP
Emergency STOP was activated, after which the START is blocked. Converter will
unblock after cancelling the START command with an inactive safety (quick) STOP.
F34-Quick reverse
Accelerated ramp-down Quick reverse is applied on the opposite polarity of the
frequency setpoint and the ramp output. For the duration of the warning, the value of
Quick reverse [807] (page 70) is displayed in FAULTS window.
W35-PC Parking
Process controller conditions to park the converter were met. For the duration of the
warning, the value of Error PC [410] (page 21) is displayed in FAULTS window.
F36-OPS on
Limit switch of the Overload Protection System (OPS) is on. For the duration of the
warning, the value of Load [854] (page 22) is displayed in FAULTS window.
F37-OPS detecion
Detection of overload limits. OPS limit switch is disabled. For the duration of the
warning, the value of Load [854] (page 22) is displayed in FAULTS window.
W38-Motor
disconnected
Motor current is too low. The motor is probably not connected or the motor parameters
do not match the connected motor. For the duration of the warning, the value of
Current MT [42] (page 16) is displayed in FAULTS window.
W39-Pantograph
outage
Voltage drop or outage of the pantograph voltage of the trolley vehicle. For the
duration of the warning, the value of Pantograph voltage [113] (page 23) is displayed
in FAULTS window.
W40-Slip restriction
Converter limited the frequency not to exceed the maximum allowed motor slip. For
the duration of the warning, the value of Slip freq. [938] (page 15) is displayed in
FAULTS window.
W41-Profibus
Timeout
Profibus master does not communicate with the Profibus module, or the Profibus
module does not communicate with the converter for a defined period of time PB
Warning timeout [815] (page 116).
W42-Modbus
Timeout
Modbus master does not communicate with the converter for a defined period of time
MB Warning timeout [962] (page 113).
F43-Limit switch 1
Limit switch 1 is switched. Configuration is possible in the group [876] (page 95).
F44-Limit switch 2
Limit switch 2 is switched. Configuration is possible in the group [877] (page 96).
F45-Limit switch 3
Limit switch 3 is switched. Configuration is possible in the group [878] (page 96).
F46-Limit switch 4
Limit switch 4 is switched. Configuration is possible in the group [879] (page 97).
F47-Set switching
Switching to another set is activated. If the message persists, it is not possible to
switch the sets (Some parameters can only be changed during stop). For the duration
of the warning, the value of [222] (page 117) is displayed in FAULTS window.
F48-Restore point
Restore point for restoring the converter settings is being created.
W49-External
warning
External warning signal is active. Source of the warning is configured in the parameter
Ext. warning signal [965] (page 111).
W50-CPU Overload
Excessive overload of the converter control processor. Control quality decreases
when this warning occurs. It is recommended to decrease the converter switching
frequency Switching frequency [6] (page 47). For the duration of the warning, the
value of load of the 10ms interrupt is displayed in FAULTS window.
F51-Initialization
During the initialization Initialization time [1154] (page 48) the converter ignores
control commands. It is used for slower superior systems.
W52-Brake
frequency
Frequency setpoint Freq. setpoint [162] (page 15) is less than Brake frequency [522]
(page 102). For the duration of the warning, the value of Brake frequency [522] (page
102) is displayed in FAULTS window.
W53-BM blocking
Blocking the switching pulses of BM from the source BM blocking [1204] (page 73).
F54-Auto on/off
Countdown to auto on/off in progress. For the duration of the warning, the value of ON
/ OFF time [1577] (page 15) is displayed in FAULTS window.
W55-Waiting
for
STOP
Waiting for the STOP command. Due to safety reasons, STOP command has to come
prior to the START command to start the drive.
W56-Low
DC
capacity
Low DC link capacity, high voltage ripple.
W57-IRC outage
Converter is detecting incorrect signals from IRC1 or IRC2. Testing can be turned off
in parameter Encoder fault mode [535] (page 109). For the duration of the warning,
the value of Freq. IRC1-IRC2 gear [1086] (page 19) is displayed in FAULTS window.
