24 Vdc supply

The 24 Vdc supply connected to control terminals 1 & 2 provides the
following functions:
• It can be used to supplement the drive's own internal 24 V supply
when multiple option modules are being used and the current drawn
by these module is greater than the drive can supply.
• It can be used as a back-up power supply to keep the control circuits
of the drive powered up when the line power supply is removed. This
allows any fieldbus modules, application modules, or serial
communications to continue to operate.
• It can be used to commission the drive when the line power supply is
not available, as the display operates correctly. However, the drive
will be in the Under voltage trip state unless either line power supply
or low voltage DC operation is enabled, therefore diagnostics may
not be possible. (Power down save parameters are not saved when
using the 24 V back-up power supply input).
• If the DC bus voltage is too low to run the main SMPS in the drive,
then the 24 V supply can be used to supply all the low voltage power
requirements of the drive. Low Under Voltage Threshold Select
(06.067) must also be enabled for this to happen.
NOTE
On size 6 and larger, the power 24 Vdc supply (terminals 51, 52) must
be connected to enable the 24 Vdc supply to be used as a backup
supply, when the line power supply is removed. If the power 24 Vdc
supply is not connected none of the above mentioned functions can be
used, "Waiting For Power Systems" will be displayed on the keypad and
no drive operations are possible. The location of the power 24 Vdc can
be identified from Figure 4-17 Location of the 24 Vdc power supply
connection on size 6 on page 80.
