2.0 N·m EtherCAT Stepper Motor with Integrated Drive

The iESSL60-36-20-17BC-EC is a 2.0 N·m EtherCAT Stepper Motor rated at 5.0 A phase current on a 36 VDC supply, with a 17-bit absolute encoder and integrated drive in a 60 mm body. The motor and drive share the housing, so the axis is installed as a single unit with one bus connection, and it is supplied with the EtherCAT ESI file for fast network setup.

EtherCAT as the Only Interface

This variant communicates solely over EtherCAT, which keeps the network clean on machines that have standardized on the protocol. There is no secondary bus to configure, and diagnostics are read through the standard EtherCAT interface.

Encoder and Closed Loop

Feedback comes from a 17-bit absolute encoder. The closed loop holds position against load disturbances, and absolute position at power-up removes the homing sequence from the machine cycle.

Specifications

• Frame size: 60 mm
• Holding torque: 2.0 N·m
• Supply voltage: 36 VDC
• Rated current: 5.0 A
• Fieldbus: EtherCAT
• Encoder: 17-bit absolute
• Control: closed loop

Thermal Behavior

The rated current of 5.0 A draws most of the heat budget at continuous duty. Provide airflow over the frame or mount it to a heat-spreading plate; the static torque figure assumes the motor is not thermally saturated. If the axis runs near the 5.0 A rating continuously, add forced airflow or a larger heat-spreading plate to keep the winding temperature inside the continuous-duty range.

Applications

• Industrial automation
• Packaging machinery
• Robotics
• CNC machine tools

Setup Notes

For synchronized lines, verify the EtherCAT cycle time against the axis inertia and the required index rate. Because the unit is EtherCAT-only, no additional protocol configuration is needed. The EtherCAT-only interface also keeps the network configuration consistent across the line, which reduces commissioning effort on machines with many axes; confirm the distributed-clock settings so all axes index together. Ask Lyenwsin for the ESI file, wiring example, and duty-cycle guidance.
