8 WIRING
8.1 General
CAUTION
1) Refer to the relevant drivers manuals for the wiring.
2) Determine the correct power supply voltage from the product label.
8.2 Wiring the LC8
DANGER
1) Do not excessively bend, pull or pinch the power cable or motor leads. Electric shock may result.
2) To avoid electric shock, disconnect the power and wait one minute before performing maintenance or inspection
on the wiring.
3) Carefully follow the wiring diagrams when making wiring connections to avoid fire or electric shock.
4) Do not reverse the motor drive leads. Also be careful not to ground the wires or short them.
5) Do not attempt to use the signal terminals for other than the specified signals.
CAUTION
1) Do not attempt to measure the insulation resistance. Damage may result.
2) Ground resistance must be lower than 0.1 Ω.
3) Install appropriate surge protection to avoid malfunction.
8.3 Wiring Diagram
6 MOUNTING
There are two mounting possibilities: Bracket and Bulkhead mounting
6.1 Mounting Dimensions
To avoid overheating keep the minimum distance from enclosure as shown
below.
Installing the controller in an enclosure may result in overheating due to
increased temperatures inside the enclosure. Ensure the enclosure is venti-
lated sufficiently to prevent the ambient temperature from exceeding 50ºC
(122ºF) for 50 Watt and 100 Watt controllers and 40°C (104°F) for 200 Watt
controllers. Additionally, allow at least 50mm (2”) above and below the con-
trollers, 20mm (.78”) between controllers and 30mm (1.18”) between the
controllers and sides of the enclosure for ventilation.
7 LC8 POSITIONING DRIVER SPECIFICATIONS
WARNING
Never operate the actuator out of specifications.
8.4 LC8 positioning driver and motor power supply
Use specification table in section 7 to determine the correct fuse or circuit breaker for protecting the LC8
controllers:
Cable Termination
Strip the wire and twist the ends. (Do not solder the core.)
The Motor/Power connector is used to connect the LC8 to the AC power supply and to connect the motor power
cable to the LC8. The Motor/Power connector has a separate plug that is inserted into the header in the LC8 so
that the wiring can be quickly disconnected and reconnected for servicing.
8.5 RS 232 interface
The RS-232 connector is used for serial communication to a PC. An RS-232 communication cable is available from
SMC or from most distributors of computer supplies.
8.6 Encoder connector
The encoder connector connects the motor encoder to the LC8. The encoder connector is a 20 pin AMP champ
series connector that mates with the encoder connector of the SMC standard actuators.
8.7 Multi-axis communication connector
The multi axis communications connector is used to connect a single LC8 master to up to 6 slaves using a multi
axis communication cable from SMC.
8.8 Command I/O connector
The Command I/O provides the input and output signals for normal operation of the LC8. All of the signals on this
connector are optically isolated from the rest of the LC8 electronics and a separate power supply is required when
using the Command I/O port. The Command I/O connector is a 26 pin AMP Champ series connector. A cable with
the appropriate mating connector is available from SMC (see Section 3.5).

9 OPERATION
WARNING
1) Never access or touch terminals and switches while energized. It may lead to electric shock.
2) Never touch any moving part of the actuator when it is powered up or operating. This may lead to injury.
CAUTION
1) Do not touch the driver radiator and motor for some time after power has been disconnected, as they heat up
when energized. It may lead to a burn.
2) Immediately stop the operation in the event of failure. There is a possibility of electric shock, injury and fire.
3) Check the rotating direction before connecting with other devices. It may cause injury and damage.
10 MAINTENANCE INSPECTION
DANGER
Do not overhaul the product, it could lead to fire and electric shock.
Check the voltage using a tester, more than 1 minute after the power is turned off before commencing
any wiring and inspection.
CAUTION
Ask SMC for repair. This product may become inoperable if disassembled.
10.1 General
It is important to perform regular maintenance inspections of the LC8 positioning driver, to optimise its
performance and safe operation. Please familiarize yourself with the information given below, this will enable you
to perform the maintenance inspections in a safe and proper manner.
Before performing an inspection it is important to ensure that the power to the positioning controller is switched
off/disconnected to avoid the risk of electric shock.
Do not touch the circuits inside the positioning driver.
Avoid performing an inspection while the positioning driver is in operation, as the heat sink may become quite hot
during operation.
Disassembling the controller may cause it to malfunction.
If a fault is detected during the inspection, contact your nearest SMC service department as soon as possible.
11 GENERAL EMC PRECAUTIONS
Noise Considerations
The "-Q" version of the LC8 Positioning Driver has been designed and tested to meet the emission and susceptibility
requirements of the CE (European Economic Area) without the aid of external filters. This compliance is based on
following the instructions in this manual for installing and wiring the LC8.
Noise Sources
Two types of noise will affect the LC8 positioning driver and all other electronic devices, radiated noise and
conducted noise.
Radiated noise is electromagnetic interference (EMI) that travels through the air and couples to the circuits and/or
cables of the LC8. Radiated noise is always present but generally at harmless levels. Circuits and cables can act
as antennas and as amounts of noise increase, signals traveling in the circuits and cables can have enough noise
coupled to them that the signal is lost in the noise. Very large amounts of EMI can even damage components.
Power equipment and cables can be unintentional sources of radiated noise. Radio equipment is designed to be a
source of radiated noise.
Conducted noise is electrical noise that travels through wires. This kind of noise is also always present but usually
harmless. Conducted noise problems are usually associated with power supply and grounding issues. If there is an
extreme amount of noise on the AC power lines it can pass through the filtering built into the LC8 and have a
negative effect on the circuit. The LC8 positioning driver has been tested to make sure that it is not susceptible to
normal amounts of radiated and conducted noise and also to make sure that it is not a significant source of radiated
or conducted noise.
Noise Suppression/Prevention
The following guidelines will insure robust performance:
A. General noise reduction
- Avoid bundling power cables (motor and power) and control cables together.
- Use shielded or twisted pair cables for control cables whenever possible.
- Ground the LC8 positioning driver and its actuator together at one point or a ground plane (metal enclosure).
B. Reduce EMI of other instruments and devices
- Use surge absorbers on the noise sources (such as magnetic contactors, AC relays, AC valves, etc) to reduce
noise.
- Separate noisy equipment or devices from the LC8 positioning driver. Maintaining the maximum physical
distance can be an effective method to reduce radiated noise couplings.
- Signal cables (I/O, encoder, communications) should be routed away from power cables. Version 1.02
C. Improve noise immunity in high noise environments
- Install ferrite filters on the encoder and signal lines (as well as RS-232 lines during setup and testing).
- Ground the shields of the encoder and the control signal lines with cable clamp fittings (Pclips).
D. Optional components to improve noise immunity
- Power Line Filter
Recommended part numbers:
Tokin GT Series or equivalent
- Ferrite EMI suppressor: The noise immunity of the driver can be improved by filtering the noise with clamp-
on ferrites on the Encoder, Command I/O and RS-232 cables. Locate ferrite beads as close as possible to the
source of noise to minimize radiation. Ferrite beads can be attached to cables with tie wraps or heat-shrink
tubing.
