Control Signal Setup Timing. Leadshine MX 3660

Below you will find brief information for Multi-axis Stepper Drive MX 3660. The MX3660 is a multi-axis stepper drive that is specially designed to allow for easy and rapid implementation of multiple axis stepper solutions. It is capable of driving multiple 2-phase stepper motors in frame sizes 17, 23, 24, and 34. It features anti-resonance, multi-stepping, digital smoothing, options of different configurations for each axis, automatic idle current reduction, and easy configurations of micro stepping and output currents via DIP switches.

Control Signal Setup Timing

To make a reliable operation, the MX3660 requires the control signals to meet the setup time requirements as follows. Otherwise losing of steps may happen.

Protection Functions

To improve reliability, the drive module incorporates some built-in protection functions. It uses one red LED to indicate the protection type. The periodic time of red is 4 s (seconds), and the blinking times of red LED indicates what protection has been activated. Because only one protection can be displayed by red LED, so the drive will decide what error to display according to their priorities. See the following protection Indications table for displaying priorities.

Over-current Protection

Over-current protection will be activated when continuous current exceeds the limit or in case of short circuit between motor coils or between motor coil and ground, and RED LED will blink once

within each periodic time.

Over-voltage Protection

When power supply voltage exceeds the limits, protection will be activated and red LED will blink twice within each periodic time.

Caution

When above protections are active, the motor shaft will be free or the LED will blink. Reset the drive by repowering it to make it function properly after removing above problems. Since there is no protection against power leads (﹢,﹣) reversal, it is critical to make sure that power supply leads correctly connected to drive.

Otherwise, the drive will be damaged instantly.
