It is prohibited to pull and plug connector P2 while the driver is powered ON, because there is
high current flowing through motor coils (even when motor is at standstill). Pulling or plugging
connector P2 with power on will cause extremely high back-EMF voltage surge, which may
damage the driver.
9. Typical Connections
A complete stepping system should include stepping motor, stepping driver, power supply and
controller (pulse generator). The following figures are two typical connections of the M415B.

10. Sequence Chart of Control Signals
In order to avoid some fault operations and deviations, PUL, DIR and ENA should abide by some
rules, shown as following diagram:

11. Protection Function
The M415B incorporates power leads (+, -) reversal protection function to protect the M415B
damaged by power leads (+, -) reversal.
12. Frequently Asked Questions
In the event that your M415B doesn
’
t operate properly, the first step is to identify whether the
problem is electrical or mechanical in nature. The next step is to isolate the system component that is
causing the problem. As part of this process you may have to disconnect the individual components
that make up your system and verify that they operate independently. It is important to document
each step in the troubleshooting process. You may need this documentation to refer back to at a later
date, and these details will greatly assist our Technical Support staff in determining the problem
should you need assistance.
Many of the problems that affect motion control systems can be traced to electrical noise, controller
software errors, or mistake in wiring.
