Motor connections
If the power supply voltage is ±15 V, the motor must be rated for 12 V for an
unbalanced connection, and must be rated 24 V for a balanced connection.
Likewise, if the power supply voltage is ±26 V, the motor must be rated for 24
V for an unbalanced connection, and must be rated 48 V for a balanced
connection.
To have the motor voltage reduced by 50%, the motor can be
connected bV and DR_GND (unbalanced).
10.15 Drive Power
The NY4130 drive power is used to connect the drive power supply to the low
power DC drive module. The NY4130 has two drive power supplies (negative
and positive). The drive power and the drive ground are designed to conduct
14 A continuous.

Note: The software disables the drive at 29 V.
The maximum voltage at which the software disables the
