Introduction

This manual describes the specifications of CNC C70. To safely use this CNC module, thoroughly study the "Precautions for Safety" on the next page before use.
Details described in this manual
At the beginning of each item, a table indicating it's specification according to the model.
CAUTION
The items that are not described in this manual must be interpreted as "not possible". This manual is written on the assumption that all option functions are added. Some functions may differ or some functions may not be usable depending on the NC system
(software) version.
General precautions
(1) When the contents of this manual is updated, the version (A, B, …) on the cover will be incremented. (2) In this manual, the machining center system is described as "M system" and the lathe system is described
as "L system".

Precautions for Safety

Always read the specifications issued by the machine maker, this manual, related manuals and attached documents before installation, operation, programming, maintenance or inspection to ensure correct use. Understand this numerical controller, safety items and cautions before using the unit. This manual ranks the safety precautions into "Danger", "Warning" and "Caution".
DANGER
When there is a great risk that the user could be subject to fatalities or serious injuries if handling is mistaken.
WARNING
CAUTION
When the user could be subject to fatalities or serious injuries if handling is mistaken.
When the user could be subject to injuries or when physical damage could occur if handling is mistaken.
Note that even items ranked as "
CAUTION
", may lead to major results depending on the situation. In any
case, important information that must always be observed is described.
DANGER
Not applicable in this manual.
WARNING
Not applicable in this manual.
CAUTION
1. Items related to product and manual
The items that are not described in this manual must be interpreted as "not possible". This manual is written on the assumption that all option functions are added. Some functions may differ or some functions may not be usable depending on the NC system
(software) version.
2. Items related to start up and maintenance
Follow the power specifications (input voltage range, frequency range, momentary power failure
time range) described in this manual.
Follow the environment conditions (ambient temperature, humidity, vibration, atmosphere)
described in this manual.
If the parameter is used to set the temperature rise detection function to invalid, overheating
may occur, thereby disabling control and possibly resulting in the axes running out of control, which in turn may result in machine damage and/or bodily injury or destruction of the unit. It is for this reason that the detection function is normally left "valid" for operation.

(Note 2)
(Note 1) This indicates the section of the power supply to which the equipment is assumed to be
connected between the public electrical power distribution network and the machinery within premises. Category II applies to equipment for which electrical power is supplied from fixed facilities. The surge voltage withstand level for up to the rated voltage of 300 V is 2500V.
(Note 2) This index indicates the degree to which conductive material is generated in terms of the
environment in which the equipment is used. In the environment corresponding to "Pollution level 2", basically only nonconductive pollution occurs, however temporary conductivity may occur due to the occasional condensing.

II. FUNCTIONAL SPECIFICATIONS

1. Control Axes

1.1 Control Axes

1. Control Axes
The NC axis, spindle, PLC axis are generically called the control axis. The NC axis is an axis that can be manually operated, or automatically operated with the machining program. The PLC axis is an axis that can be controlled from the PLC ladder.
1.1 Control Axes
1.1.1 Number of Basic Control Axes (NC axes)
M system : { 3 axes L system : { 3 axes
1.1.2 Max. Number of Control Axes (NC axes + Spindles + PLC axes)
A number of axes that are within the maximum number of control axes, and that does not exceed the maximum number given for the NC axis, spindle and PLC axis can be used. For example, if 16 NC axes are used, this alone is the maximum number of control axes, so a spindle and PLC axis cannot be connected.
Max. number of control axes (NC axes + spindles + PLC axes)
M system : 16 axes L system : 16 axes
Max. number of NC axes (in total for all the part systems)
M system : 16 axes L system : 16 axes
Max. number of spindles
M system : 7 axes L system : 4 axes
Max. number of PLC axes
M system : 7 axes L system : 7 axes
1.1.4 Number of Simultaneous Contouring Control Axes
Simultaneous control of up to four axes or less is possible in the same part system. However, for actual use, the machine tool builder specification will apply.
M system : 4 axes L system : 4 axes
1.1.5 Max. Number of NC Axes in a Part System
M system : 8 axes L system : 8 axes
II

1. Control Axes

1.2 Control Part System

1.2.1 Standard Number of Part Systems
M system : 1 part system L system : 1 part system
1.2.2 Max. Number of Part Systems
M system : Δ7 part systems L system : Δ3 part systems
For actual use, the machine tool builder specification will apply.

1.3 Control Axes and Operation Modes

1.3.2 Memory Mode
M system : { L system : {
The machining programs stored in the memory of the NC unit are run.
1.3.3 MDI Mode
1.2 Control Part System
M system : { L system : {
The MDI data stored in the memory of the NC unit is executed. Once executed, the MDI data is set to the "setting incomplete" status, and the data will not be executed unless the "setting completed" status is established by performing screen operations.
