  • Page 6: Introduction

    1.1 Overview EM522-CAN is one of the new high performance stepper drive which can support CANopen communication protocol. By implementing latest 32-bit DSP technology, this stepper drive is able to power 2 phase and 4 phase stepper motors. It can configure drive parameters and motor operation in real time via CANopen commander.

    3. Connection Pin Assignment & DIP Switch & LED Indication The EM522-CAN has three connector blocks P1&P2&P3 (see above picture). P1 is for IO signals connections, P2 is for power and motor connections, and P3 is for CAN communication connection. The following tables are brief descriptions of the two connectors.

    EM522-CAN Field bus Stepper Drive User Manual V1.0 4.3.2 Connections of 6-lead Motor Like 8 lead stepping motors, 6 lead motors have two configurations available for high speed or high torque operations. The higher speed configuration, or half coil, is described, because it uses one half of the motor’s inductor windings. The higher torque configuration, or full coil, uses the full coil windings.

  • Page 15: Power Supply Selection

    4.4.2 Power Supply Sharing Multiple EM522-CAN drives can share one power supply to reduce cost, if that power supply has enough power capacity. To avoid cross interference, connect each stepper drive directly to the shared power supply separately. To avoid cross interference, DO NOT daisy-chain connect the power supply input pins of the Drivers.
