Terminal blocks TB4 and TB6 (B Frame drives & up) allow the
drive power supplies to be operated from an external voltage source.
Both terminal blocks are located on the Base Driver Board and are
accessible from the front of the drive. See Figure 2.1 for locations.

TB4 can be used to externally power the low voltage power supply,
allowing operation of drive control functions in the absence of bus
voltage. Applying proper voltage to TB4 (see Table 2.J) provides
+5V,

±

15V and isolated 12V outputs for:

Main Control Board (Control Interface Boards, RIO Board, etc.)

SCANport

t (HIM, etc.)

Encoder(s)

ELMS

Precharge

Any DC fans in the drive

TB6 can be used to externally power the high voltage power supply
which provides inverter IGBT drive voltage and the low voltage
necessary to power the low voltage power supply. This allows
operation of the drive in the absence of bus voltage.

The maximum and minimum wire size accepted by TB4 is 2.1 and
0.06 mm

2

(14 and 30 AWG). Wire sizes for TB6 are 5.3 and 0.06

mm

2

(10 and 30 AWG). Use Copper wire Only with a minimum

temperature rating of 75

°

C. Maximum torque for both terminal

blocks is 0.57 N-m (5 lb.-in.).

The power source used to drive a power supply must be capable of providing the peak current at
startup. A “flat“ current or power limit is acceptable, but a foldback current limit may trip at startup,
never allowing the supply to start.

2 Must be supplied from a Class 2 Limited Power Source.

3 Must be supplied from a source that is provided with transient voltage surge suppression such that

transients are suppressed to 6000V peak maximum or less.
