UF-48Vxx EtherCAT 48 V DC servo drive

The UF platform with the EtherCAT interface board. This is the variant that supports STO, and the one I specify when a machine has several axes that must move together or when the safety case needs a torque-off function.

What to know about this drive

EtherCAT variants use RS485 for commissioning daisy-chaining between drives of the same type; the other three interfaces use MiniUSB.
The -P suffix adds 0.1 g force-control resolution and 16-bit current sampling.
EtherCAT is the only interface on this platform that supports STO. If your safety case needs it, that decides the bus for you.

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. Send me the motor model, bus type and axis count and I will come back with a written answer.
