3.3 LED Light Indication

There are two LED lights for DM542E. The GREEN one is the power indicator which will be always on generally. The
RED one is a protection indicator which will flash 1-2 times in a 3-second period, when protection enabled for a
DM542E. Different number of flashes indicates different protection type (read section 11 for detail).

4. Control Signal Connector (P1) Interface

The DM542E can accept differential and single-ended inputs (including open-collector and PNP output). The DM542E
has 3 optically isolated logic inputs which are located on connector P1 to accept line drive control signals. These inputs
are isolated to minimize or eliminate electrical noises coupled with the drive control signals. Recommend using line
drive control signals to increase noise immunity for the drive in interference environments. In the following figures,
connections to open-collector and PNP signals are illustrated.

5. Motor Connection

The DM542E can drive 2-phase and 4-pahse bipolar hybrid stepper motors with 4, 6, or 8 wires.

5.1 Connections of 4-lead Motor

The 4 lead motors are the least flexible and easy to connect. And the Speed – torque of motor depends on winding
inductance. The output current from drive that is multiply the specified phase current by 1.4 to determine the peak
output current.

5.2 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.
