Inovance H2U Series User Manual

H2U Series PLC User Manual
Thank you for purchasing the H2U series programmable logic controller
(PLC) independently developed by Inovance Control Technology Co., Ltd.
Read the manual carefully to be familiar with the product features and be
able to use the product safely.
This manual describes the specification, features and usage of the H2U
series PLC. For the developing environment and design method of user
programs, see the Autoshop On-line Help of Inovance.
The H2U series PLC has the following features:
◆ The built-in program memory space reaches up to 16K steps.
◆ The internal large-capacity power supply can directly apply power to
sensors, HMI, and external auxiliary relays.
◆ It provides multiple high-speed I/O terminals, and has rich motion and
positioning control functions.
◆ It has four independent communication ports and supports various
communication protocols including Modbus, facilitating system
integration.
◆ The comprehensive encryption function protects intellectual property
rights of the user.
◆ It comes with fast execution speed and supports up to 128
subprograms and 21 interrupt subprograms. Each subprogram has the
parameter call and independent password security functions.
Safety Information and Precautions
In Design
■
DANGER
◆ Provide a safety circuit outside the PLC in the application so that the
control system can still work safely even if external power failure or
PLC fault occurs.
◆ In the external circuit of the PLC, an emergency stop circuit, a
protection circuit, an interlock circuit of forward/reverse rotation
operation, and position upper/lower limit interlock circuit are necessary
to prevent equipment damage
◆ The PLC is designed for indoor electric environment and is installed in
an overvoltage category 2 environment. A lightning protection device
must be installed for the power supply system, so that lightening
overvoltage is not applied on terminals of the PLC, avoiding damage to
the equipment.
During Installation
■
WARNING
◆ Install the PLC in places free from dust, oil smoke, conducting dust,
corrosive gas, combustible gas, high temperature, condensation, wind
& rain, vibration and shock. In addition, electric shock, fi re, malfunction
may also cause damage and deterioration to the equipment.
◆ During screw hole processing and wiring, ensure that no metal filing
and cable end fall into the ventilation hole of the controller, because
such stuff may cause a fi re, fault, or malfunction.
◆ After installation of the newly purchased PLC is complete, ensure that
there is no foreign stuff on the surface of ventilation. Failure to comply
may result in poor cooling effect during running, which may lead to a
fi re, fault or malfunction.
◆ The installation and wiring must be secure and reliable. Poor contact
may cause malfunction.
At Wiring
■
DANGER
◆ Ensure that all power supplies are cut off before installation or wiring.
◆ During screw hole processing and wiring, ensure that no metal fi lings
or cable end drops into ventilation holes of the controller. Failure to
comply may result in a fi re, fault or malfunction.
◆ Perform wiring or plug/remove the cable connector only after power-off.
Failure to comply may result in electric shock or damage to the circuit.
WARNING
◆ Use shielded cables for high-frequency signal input/output in
applications with severe interference to enhance anti-interference
capacity of the system.
◆ Suitable earthing connection shall be provided by the end system. The
earth wire must be connected only to the earthing point on terminal
which is marked with the earth symbol. The earth must be over 2 mm².
