Description

FD1.1EC and FD1.2EC, part of the FD family of drives, boast a compact design tailored for direct mounting on motor end-shields. These drives are powered by ARM-based microcontrollers, utilizing ultra-low RDS-on MOSFETs and Hall-effect current sensors to enhance power efficiency significantly.
FD1.1EC and FD1.2EC are equipped with a 12-bit single-turn magnetic encoder to serve multiple functions: it verifies the execution of ordered steps, it modulates motor current with the load, it allows the accumulation of steps that cannot be executed because of load torque, and more, detailed comprehensively in the firmware manual.
They feature configurable I/Os, offering 4 digital inputs and 2 digital outputs. These ports can serve as step, direction, quadrature steps, homing sensor, alarm, start, stop, torque-off, etc.
Communication occurs via EtherCAT using CoE (CAN over EtherCAT) and FoE protocols through industrial M12 circular connectors. Additionally, a RS-232 port, accessible through one of the screw caps, facilitates firmware programming, parameter adjustment, and real-time monitoring during operation.
Compared to its predecessor, FD1.1E, FD1.1EC and FD1.2EC introduce several enhancements. Its redesigned enclosure accommodates NEMA 34 motors, alongside NEMA 23 and 24. The M12 type connectors, located at the rear, offer additional I/O options. Notably, there’s galvanic insulation between power GND and logic GND, ensuring robust electrical separation.
The drive logic is supplied only from external VEXT 24 VDC, which allows to keep communication and multiturn position counting active in case of loss of power. FD1.1EC drive’s logic relies solely on an external VEXT 24 VDC supply, while FD1.2EC logic can be supplied by VEXT and by main power supply VPOW. This setup guarantees active communication and multiturn position counting even in the event of power loss, enhancing the drive’s reliability and operational continuity
