7.2.1 Power supply requirements
The choice of a power supply is mainly determined by voltage and current ratings of the power supply. Main
requirements of the Nix power supply are:
•
The
voltage
should be the targeted for the motor. This means up to
48 V
for the
NIX-x/48
and up to
170 V
for the
NIX-5/170
. Make sure that the voltage rating of the power supply does not exceed the voltage rating
of the motor, otherwise it could be damaged.
•
The
current
should be the one able to provide the phase peak current of the application. This means up to
10 A
for the
NIX-5/xx
and up to
20 A
for the
NIX-10/48
. Make sure that the current rating for the power
supply is at least as high as the motor.
•
The voltage and current range can be decreased due to the motor requirements.
Although the logic supply accepts a wide voltage range, a power supply of 24 V and 5 W is recommended for the
NIX-5/170-y-z.
Further information on how to dimension a power supply for the Ingenia drives can be found

Description
Inrush current
During power up a short duration high current peak is needed to charge the drive internal DC bus capacitors (see
specification page to know the value of the capacitors), this is called inrush current. This current will only be limited
by the power supply, the wiring and connectors resistance, the drive reverse polarity protection resistance (~ 65
mΩ) and the bus capacitance equivalent series resistance (ESR ~ 5 mΩ).
•
The board could be hot during < 1 min after disconnection.
•
Preferably do not disconnect the supply while having a motor in motion.
•
If working with Motion Lab with USB connection, preferably disconnect the drive from the
application before disconnecting. This prevents COM port corruption.
