Tab. 10-16: 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 between +V and DR_GND (unbalanced).
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.

Negative drive power –15 V ... –26 V
voltage
Note: Positive and negative drive power voltage must
always be symmetrical.
Absolute maximum +29 V (positive drive power)
rating
–29 V (negative driver power)
Note: The software disables the drive at 29 V.
The maximum voltage at which the software disables the
drive can only be set to a user defined value lower than
