Perform periodic inspections to maintain your equipment, as well as inspections before operation of
the servo and motor.
Periodically check to confirm the screws are securely tightened. This includes the screws in
the servo drive, the connection screws between the motor shaft and the machine, and the
connection screws between the terminal block and machine.
Prevent oil, water, metallic particles, and other foreign matter from entering the control box
or ventilation equipment. Protect the servo drive from any drill cuttings.
If the control box is installed in a location where dust or harmful gas are present, ensure the
dust or harmful gas cannot enter the control box.
Make sure to wire encoders and other devices in the proper sequence to avoid sudden
unintended acceleration or damage to the motor.
To avoid electric shock, connect the ground terminal of the servo drive to the ground
terminal of the control box. If wiring must be added or modified, wait at least 10 minutes
after disconnecting the servo drive from the power supply or discharge the electricity with a
discharge device.
Isolate the wires at the wiring terminal.
Make sure the wiring is correct to avoid damage or any abnormal operation.
Check for and remove any electrically conductive objects, including metal sheet and screws,
or flammable objects inside or near the servo drive.
Make sure the emergency stop switch is OFF.
To ensure the electromagnetic brake works, make sure the stop and circuit breaker functions
are working properly.
Reduce the electromagnetic interference if there is electromagnetic interference with the
peripheral devices.
Make sure the external voltage level of the servo drive is correct.
The encoder cable should be protected from excessive stress - make sure the cable is not
worn or stretched.
Contact AutomationDirect if the servo motor vibrates or makes unusual noise during
operation.
Make sure the parameter settings are correct. Different machines have different
characteristics. Adjust the parameters according to the characteristics of each machine.
Reset the parameters when the servo drive is in the Servo OFF status to avoid possible
malfunction.
If there is no contact noise or other abnormal noise when the relay is operating, contact
AutomationDirect.
Contact AutomationDirect if the power indicator or LED display does not function properly.

NOTE: Do not use APC-VSCN1T(xx)-AD or APC-VPCN1T-AD if using PLC/Drive serial
communication. Communication may be poor due to disconnection in cable shields. Build the
structure of a single connector holding individual lines of RS-422 communication cables and
input/output cables. Make sure to use shielded twisted cables (Twisted Pair Wire) for RS-422
communication cable.
NOTE: PE between the servo motor and the servo and between the servo and the device must
be connected.

NOTE: When connecting a single RS422 servo
to an RS485 PLC, use the following wiring:
PLC RS485 terminals
For best performance (and when communicating with multiple servos),
use an RS485 to RS422 adapter with the PLC
For the most reliable PLC/drive communication, limit the drive baud
rate (0x3002) to a maximum of 19,200 baud.
NOTE: Input signals DI1–DI10 and output signals DO1–DO8 are factory default signals and can
be reconfigured. Note that DO6-DO8 are permanently fixed as status output signals, but all
other digital I/O can be reprogrammed.

The LED status display can contain a variety of information, including the status of the drive’s
operating state, digital inputs, digital outputs, alarms, and warnings. Please refer to Chapter 10 of the
User Manual to see details of using the keypad on the front of the drive to monitor status, change drive
parameters, and control certain special functions of the drive (example: you can jog the drive from the
keypad).
AutomationDirect recommends skipping Chapter 10 and proceeding straight to using the Drive CM
software for maintenance, configuration, commissioning, and debugging.

The LS Electric Drive CM software does not include “Are you sure?” types of warnings. When you make
a change in the SW it takes place immediately in the drive, even settings that initiate motion.
Example 1:
When you go to the JOG screen and press “Enable”, the drive Enables
immediately.
Example 2:
When you change a Digital Input from active low to active high, the definition
changes immediately by pushing the “Edge” button. In the picture to the right,
Input #1 is configured for Servo On. If the input is physically low and you press
the Edge button, the input’s definition is changed to active low and the servo will
immediately be enabled.
There is nothing wrong with this approach, but it may be more direct than most
software packages that are in use today.
Drive CM software provides the fastest and easiest way to set up the LS Electric
L7C drive. The following steps show how to get started with the software and a few key features.
Before starting, you will need:
•
PC with Windows 8 or later.
•
PC USB port
•
USB Type A to miniB cable (SV2-PGM-USB15 is a good choice due to the dual ferrite filters and
opto-isolator included with the cable. This USB cable is helpful when dealing with PC to Drive
connectivity issues due to EMI)
Step 1
Download and install Drive CM Software from the AutomationDirect L7C servo drives support page at
https://support.automationdirect.com/products/lselectric.html.
Step 2
Connect the servo drive USB port to the PC USB port using a standard USB-A to USB-mini-B cable.
