ISD – Integrated Stepless Drive

ISD – Integrated Stepless Drive

Product catalog summary

Hardware Features
The integrated stepless drive operates with a nominal power supply of 120Vdc, ranging from 65Vdc to 130Vdc, and a logic supply of 20-130Vdc. The maximum current is internally set and depends on the motor. Feedback is provided by incremental and multiturn absolute encoders, with an incremental encoder output available only in the APD version. The drive includes 3 digital IN (24Vdc optoisolated PNP), 2 digital IN for general purposes or encoder input, 2 digital OUT (24Vdc optoisolated PNP), 2 bidirectional digital OUT (24Vdc optoisolated PNP), and 1 analog OUT ranging from -10V to +10V. Interfaces include CANopen, Profibus-DP, Modbus RS485, and Pulse/direction.

Functional Features
The drive supports speed, position, and torque control, along with gearing, electronic cams, and interpolated mode. It is programmable according to the IEC61131 standard using the ST language. Accessories include a serial interface cable for debugging and a power supply of AC/DC 80-170Vdc.

Ordering Code
The ordering code for the drive includes type, size, and interface options, such as ISD 1281 CAN 3 0 1, with various configurations for connectors and shaft diameters.

Technical Specifications
The document provides detailed specifications for different models (ISD 1281, ISD 1271, ISD 1261), including holding torque, phase current, rotor inertia, phase inductance, and weight. Dimensions and shaft sections are also specified for each model.

Motor Couplings
The document describes the integration of stepless drives with planetary gearboxes, detailing torque, flange types, and compatibility with various gearbox models (EP55, EP75, EP90, EP120, EP155, REP075, REP100, REP125, REP150).
