Update rate Background
The drive can operate from either a high voltage supply or a low voltage supply, usually from a battery. Different methods are used to connect the low
voltage battery supply depending on the frame size of the drive. This parameter, which indicates which supply is active, is set up to the correct value
just as the UU trip is reset. A low voltage battery supply should not be used without first consulting the appropriate documentation on the power and
control connections required for this mode.
0: Normal high voltage supply
The drive is operating in normal high voltage supply mode.
SP1xxx, SP2xxx, SP3xxx:
The drive is using the main power terminals to derive its control supplies. The drive will operate normally. Parameters that are saved at power-down
are saved when the supply is removed and a UU trip occurs.
SP4xxx, SP5xxx, SP6xxx, SPMxxxx:
The drive is using the main power terminals to derive its control supplies and the battery mode enable power supply input has no supply connected.
The drive will operate normally. Parameters that are saved at power-down are saved when the supply is removed and a UU trip occurs

1: Low voltage battery supply

The drive is operating in low voltage battery supply mode.
SP1xxx, SP2xxx, SP3xxx:
The drive is using the low voltage auxiliary power input to derive the power circuit supplies (i.e. gate drives, fans, etc.). The main power terminals can
be connected to a different supply of any voltage up to the maximum normal supply level. All parameters voltage based parameters are calculated
from the auxiliary supply level and not the supply from the main power terminals. If the auxiliary supply and the main supply are different then these
parameters will not be correct. Parameters that are saved at power-down are not saved when the power is removed in this mode.
SP4xxx and larger:
The drive is using the battery mode enable input to derive the power circuit supplies (i.e. gate drives, fans, etc.) A low voltage DC supply is connected
to the DC power terminals. All parameters that are calculated based on voltage are derived from the voltage connected to the power terminals.
Parameters that are saved at power-down are not saved when the power is removed in this mode.
For all sizes of drive in low voltage battery mode, 24V must also be supplied via the 24V control board power supply input. The drive will operate
normally except that mains loss detection is disabled, the braking IGBT will only operate when the drive is enabled, and the voltage levels contained
in the following table are used instead of the normal high voltage levels whatever the voltage rating of the drive.
Voltage level
DC_VOLTAGE_MAX
Braking IGBT threshold voltage
Under voltage trip level
Restart voltage level after UU trip
Full scale voltage measurement and the over voltage trip level are defined by DC_VOLTAGE_MAX. However, the maximum level of the low voltage
battery supply voltage should not normally exceed 90% of this value to avoid spurious over voltage trips.

Update rate Background
The drive thermal model system normally controls the fan speed, however the fan can be forced to operate at full speed if this parameter is set to 1.
When this is set to 1 the fan remains at full speed until 10s after this parameter is set to zero.
