Overview
Thank you for purchasing the GL10-2PH high-speed differential pulse positioning module developed and
manufactured independently by Inovance.
This product delivers 2*1 MHz high-speed differential output. It supports multiple pulse output modes, including
dir pulse (required) or CW + CCW. It also supports homing positioning and left and right limiting. This
product is a perfect solution for sophisticated manufacture industries which involves a large number of axes, such
as mobile phone manufacture and TP. This guide describes the specifications, characteristics and using methods
of the product. Please read this guide carefully before using to ensure safe usage. Visit our website (

Safety Levels and Definitions
WARNING
: Indicates that failure to comply with the notice may result in severe personal injuries or even death.
CAUTION
: The “CAUTION” sign indicates that failure to comply with the notice may result in minor or moderate
personal injury or damage to the equipment.
Please keep this guide well so that it can be read when necessary and forward this guide to the end user.
During control system design
WARNING
◆
Provide a safety circuit outside the PLC so that the control system can still work safely once external power failure or
PLC fault occurs.
◆ Add a fuse or circuit breaker because the module may smoke or catch fire due to long-time overcurrent caused by
operation above rated current or load short-circuit.
CAUTION
◆ An emergency stop circuit, a protection circuit, a forward/reverse operation interlocked circuit, and a upper position
limit and lower position limit interlocked circuit must be set in the external circuits of PLC to prevent damage to the
machine.
◆ To ensure safe operation, for the output signals that may cause critical accidents, please design external protection
circuit and safety mechanism;
◆ Once PLC CPU detects abnormality in the system , all outputs may be closed; however, when a fault occurs in the
controller circuit, the output may not be under control. Therefore, it is necessary to design an appropriate external
control circuit to ensure normal operation;
◆ If the PLC output units such as relays or transistors are damaged, the output may fail to switch between ON and OFF
states according to the commands;
◆
The PLC is designed to be used in indoor electrical environment (overvoltage category II). The power supply must have
a system-level lightning protection device, assuring that overvoltage due to lightning shock cannot be applied to the
PLC power supply input terminals, signal input terminals and output terminals and so forth, so as to avoid damage to
the equipment.

Installation
WARNING
◆
Installation must be carried out by the specialists who have received the necessary electrical training and understood
enough electrical knowledge.
◆ Disconnect all external power supplies of the system before removing/installing the module. Failure to do so may
result in electric shock, module fault or malfunction.
◆ Do not use the PLC where there are dust, oil smoke, conductive dust, corrosive or combustible gases, or exposed to
high temperature, condensation, wind & rain, or subject to vibration and impact. Electric shock, fire and malfunction
may also result in damage or deterioration to the product.
◆
The PLC is open-type equipment that must be installed in a control cabinet with lock (cabinet housing protection
＞IP20). Only the personnel who have received the necessary electrical training and understood enough electrical
knowledge can open the cabinet.
CAUTION
◆ Prevent metal filings and wire ends from dropping into ventilation holes of the PLC during installation. Failure to
comply may result in fire, fault and malfunction.
◆ Ensure there are no foreign matters on ventilation surface. Failure to comply may result in poor ventilation, which may
cause fire, fault and malfunction.
◆ Ensure the module is connected to the respective connector securely and hook the module firmly. Improper
installation may result in malfunction, fault or fall-off.
Wiring
WARNING
◆
Wiring must be carried out by personnel who have received the necessary electrical training and understood enough
electrical knowledge.
◆ Disconnect all external power supplies of the system before wiring. Failure to comply may result in electric shock,
module fault or malfunction.
◆ Install the terminal cover attached to the product before power-on or operation after wiring is completed. Failure to
comply may result in electric shock
◆
Perform good insulation on terminals so that insulation distance between cables will not reduce after cables are
connected to terminals. Failure to comply may result in electric shock or damage to the equipment.
CAUTION
◆ Prevent dropping metal filings and wire ends drop into ventilation holes of the PLC at wiring. Failure to comply may
result in fire, fault and malfunction.
◆ The external wiring specification and installation method must comply with local regulations. For details, see the wiring
section in this guide.
◆ To ensure safety of equipment and operator, use cables with sufficient diameter and connect the cables to ground
reliably.
◆ Ensure that all cables are connected to the correct interface. Failure to comply may result in module and external
equipment fault.
◆ Tighten bolts on the terminal block in the specified torque range. If the terminal is not tight, short-circuit, fire or
malfunction may be caused. If the terminal is too tight, fall-off, short-circuit, fire or malfunction may be caused.
◆ If the connector is used to connect with external equipment, perform correct crimping or welding with the tool
specified by manufacturer. If connection is in poor contact, short-circuit, fire or malfunction may be caused.
◆ A label on the top of the module is to prevent foreign matters entering the module. Do not remove the label during
wiring. Remember to remove it before system operation, facilitating ventilation.
◆ Do not bundle control wires, communication wires and power cables together. They must be run with distance of more
than 100 mm. Otherwise, noise may result in malfunction.
◆ Select shielded cable for high-frequency signal input/output in applications with serious interference so as to enhance
system anti-interference ability.
Operation and Maintenance
WARNING
◆ Maintenance & inspection must be carried out by personnel who have the necessary electrical training and experience.
◆ Do not touch the terminals while the power is on. Failure to comply may result in electric shock or malfunction.
◆ Disconnect all external power supplies of the system before cleaning the module or re-tightening screws on the terminal
block or screws of the connector. Failure to comply may result in electric shock.
◆ Disconnect all external power supplies of the system before removing the module or connecting/removing the
communication wirings. Failure to comply may result in electric shock or malfunction.
CAUTION
◆ Get with the guide and ensure safety before online modification, forcible output, and RUN/STOP operation.
◆ Disconnect the power supply before installing/removing the extension card.
Disposal
CAUTION
◆ Treat scrapped module as industrial waste. Dispose the battery according to local laws and regulations.
