5.4.1 Power connector
A two pin Molex MegaFit™ connector (Molex part no. 172065-0002) is available for power supply connection.
Mating connector housing e.g. Molex 171692-0102, contacts Molex 172063-0312. Please note that there are
alternative options available from Molex for both, housing and contacts.

+48V
Power supply
input
Power supply input. +24V … +48V +/- 10% regulated power
supply input. Supply input for all three motor driver
stages and logic supply.
Table 5.14: Power supply Brick: Power connector
CAUTION
Always keep the power supply voltage (+48V) below the upper limit of 53V!
Otherwise the driver electronics will be seriously damaged. Especially, when the selected operating voltage
is near the upper limit a regulated power supply is highly recommended.
Always keep the logic power supply voltage (+48V_LOGIC) above or equal to the main power supply!
Otherwise the on-board electronics (diode connection between +48V main power supply input and +48V
logic supply input) might be seriously damaged.
5.4.2 Control connector
A four pin Molex MicroFit™ connector (Molex part no. 436500415) is used for the driver stage enable signal and
optional separate logic supply input. Mating connector housing e.g. Molex 43645-0400, contacts Molex 43030-0007.
Please note that there are alternative options available from Molex for both, housing and contacts.

input
Separate logic supply input. May be used in order to
keep digital / logic part alive while driver stage is not
supplied (Power supply input via Power connector either
switched off or disconnected).

ENABLE
Input
Driver stage enable input (logic high). Maybe connected
to pin 3 / +48V_LOGIC in order to enable driver.

CAUTION
Always keep the digital logic power supply voltage (+48V_LOGIC) below the upper limit of 53V!
Otherwise the on-board electronics might be seriously damaged. Especially, when the selected operating
voltage is near the upper limit a regulated power supply is highly recommended.
Always keep the logic power supply voltage (+48V_LOGIC) above or equal to the main power supply
(on the Power supply connector)!
Otherwise the on-board electronics (diode connection between +48V main power supply input and +48V
logic supply input) might be seriously damaged.
