5 WARNINGS
A sample disley
Description
F1-PWM Reset
Inverter outputs are blocked. RESET sources can be a binary input or any signal (see
Reset source [645] (page 39)).
W2-DC charging
W3-System
problem
Software problem occurred. Please, contact the service.
W4-24V Overload
24V power supply voltage dropped under 22V. 24V supply is probably overloaded. For
the duration of the warning, the value of Voltage 24V [72] (page 25) is displayed in
FAULTS window.
F5-Power
restriction
Power restriction after reaching critical temperature or an overload status. Power
restriction function is configured in the parameter Power restriction (PR) [700] (page 45).
For the duration of the warning, the value of Power restriction [809] (page 19) is
displayed in FAULTS window.
W6-Cooler
temperature
High cooler temperature. Cooler temperature Cooler temperature [74] (page 26)
exceeded the value defined by the parameter Cooler temperature warning [699] (page
78). If the automatic power restriction Power restriction (PR) [700] (page 45) function is
turned on, the inverter can restrict power. Life cycle of the device decreases when the
device is overheated excessively and very often. For the duration of the warning, the
value of Cooler temperature [74] (page 26) is displayed in FAULTS window.
W7-CB
temperature
Igh temperature of control board. CB temperature CB temperature [75] (page 26)
exceeded value of parameter CB temperature warning [870] (page 78). Life cycle of the
device decreases when the device is overheated excessively and very often. For the
duration of the warning, the value of CB temperature [75] (page 26) is displayed in
FAULTS window.
W8-DC
Undervoltage
Low voltage of the DC link. The value DC Voltage [46] (page 19) dropped under the fault
limit DC Undervoltage - control and evaluation of other faults is blocked. For the duration
of the warning, the value of DC Voltage [46] (page 19) is displayed in FAULTS window.
W9-PWM
saturation
Inverter reached maximum voltage on the output. At actual voltage value of the DC link,
duty cycle of the PWM modulation is at maximum and the current controllers are
saturated. Quality of the regulation decreases. For the duration of the warning, the value
of Modulation index [750] (page 19) is displayed in FAULTS window.
W10-INV
Overload
Inverter is overloaded - inverter integral Thermal integral INV [440] (page 26) exceeded
the 90% value and the fault " E8-Inverter overload (page 32)" can occur shortly, after
which the inverter is blocked for a longer time! If the automatic power restriction Power
restriction (PR) [700] (page 45) function is turned on, the inverter may restrict power. For
the duration of the warning, the value of Thermal integral INV [440] (page 26) is
displayed in FAULTS window.
W11-Fan error
Fans on the inverter cooler are damaged or clogged by debris. If the problem is not
eliminated, inverter overheating and other faults and warnings can occur.
W12-Replace the
battery
Voltage of the 3V battery of the control card dropped under the 2.7V value. If the battery
is not replaced, loss of settings and saved history settings is impending. For the duration
of the warning, the value of Battery voltage [759] (page 25) is displayed in FAULTS
window.
W13-External
temperature
Cooler temperature ETP Temperature [799] (page 24) exceeded the value defined by the
parameter ETP Warning [796] (page 71). For the duration of the warning, the value of
ETP Temperature [799] (page 24) is displayed in FAULTS window.
W14-IGBT
Overheating
Power module is thermally overloaded. Inverter operates at high current on high switching
frequency. For the duration of the warning, the value of the maximal IGBT current is
displayed in FAULTS window.
W15-Set
date
and time
Date and time have not been set.
W16-Reserved
Reserved
F17-Auto off
Inverter performed automatic shutdown (auto off), because the function Auto off [681]
(page 40) was turned on and the condition of operation was not satisfied. Time to the next
trial for successful operation is displayed in ON / OFF time [686] (page 18). For the
duration of the warning, the value of ON / OFF time [686] (page 18) is displayed in
FAULTS window.
