UF-48Vxx Modbus 48 V DC servo drive
The UF platform with the Modbus-RTU interface board. Modbus is the pragmatic choice when the machine already talks Modbus to everything else - the axis becomes one more register block rather than a new protocol to teach the controls team.

What to know about this drive
- A full Modbus register dictionary is published - every parameter, its address, data type and scaling is documented, which saves an afternoon of guessing.
- Modbus-RTU does not support STO on this platform.
- For a machine that also needs EtherCAT elsewhere, mixing buses is normal, but it does mean two commissioning toolchains.
Other UF interface options
EtherCAT
Supports STO, and the variant to specify when axes have to be synchronised.
CANopen
Point-to-point bus for single-axis machines. No STO.
Modbus-RTU
Pragmatic when the machine already speaks Modbus everywhere else. No STO.
Pulse and direction
The retrofit route into an existing motion controller. No STO.
Pricing, lead time and the exact ordering code are confirmed on quotation.
