Start mode
EdgE-r:
Following power ON or reset, the drive
will not start if a start signasl (FWD/REV) is still
present. To start DE1 a rising edge is necessary.
Auto-0
: The device will restart automatically
after a fault message if the supply voltage is not
switched off and the start command (FWD or REV)
is still present.
Auto-1
-
Auto-9
: 1 to 9 automatic start attempts
at 20-s intervals if the supply voltage is not
switched off and the start command (FWD or REV)
is still present. If the DE1 device does not start
automatically after the last selected start
attempt, it will be switched off with the fault
message. It will then have to be RESET (supply
voltage OFF-ON (power cycling), start command
with rising edge, or STOP command).

OvervoltageControl
0/1
0
Overvoltage control
The overvoltage control function (OV) will prevent
the DE1 device from being switched off if too
much energy is being fed into the DC link during
the motor's regenerative operation and the DC
link voltage increases to an excessive value as a
result:
0
: OV active. During deceleration, the configured
ramp time (P-02) will be automatically
lengthened. During continuous operation, the
output frequency (speed) will be temporarily
increased.
1
: OV locked (shutdown with a fault message).

AutoThermalManagement

Switching frequency, temperature
management
The temperature management function will
automatically lower the switching frequency
(P-29) if the heat sink in the power section gets
too hot.
This will reduce switching losses and prevent a
shutdown due to excess temperature.
0
: activated
1
: deactivated
Note:
This function must be turned off (1 = constant
switching frequency) if the DE1 device is being run
with a sine filter at its output.
