MITSUBISHI ELECTRIC M800, M80 User Manual

Introduction

This manual is a guide for using the MITSUBISHI CNC M800/M80 Series.

This manual is prepared on the assumption that your machine is provided with all of M800/M80 Series functions. Confirm the functions available for your NC before proceeding to operation by referring to the specification issued by the machine manufacturer.

Notes on Reading This Manual

(1)This manual explains general parameters as viewed from the NC.

For information about each machine tool, refer to manuals issued from the machine manufacturer.

If the descriptions relating to "restrictions" and "allowable conditions" conflict between this manual and the machine manufacturer's instruction manual, the later has priority over the former.

(2)This manual is intended to contain as much descriptions as possible even about special operations. The operations to which no reference is made in this manual should be considered impossible.

CAUTION

For items described as "Restrictions" or "Usable State" in this manual, the instruction manual issued by the machine tool builder takes precedence over this manual.

Items not described in this manual must be interpreted as "not possible".

This manual is written on the assumption that all option functions are added. Refer to the specifications issued by the machine tool builder before starting use.

Refer to the Instruction Manual issued by each machine tool builder for details on each machine tool.

Some screens and functions may differ depending on the NC system (or its version), and some functions may not be possible. Please confirm the specifications before use.

Precautions for Safety

Always read the specifications issued by the machine tool builder, 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 the user may be subject to imminent fatalities or major injuries if handling is mistaken.

WARNING

When the user may be subject to fatalities or major injuries if handling is mistaken.

CAUTION

When the user may be subject to injuries or when physical damage may 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.

The following sings indicate prohibition and compulsory.

This sign indicates prohibited behavior (must not do). For example, indicates "Keep fire away".

This sign indicated a thing that is pompously (must do).

For example, indicates "it must be grounded".

The meaning of each pictorial sing is as follows.

CAUTION	CAUTION	CAUTION HOT	Danger	Danger
	rotated object		Electric shock risk	explosive
Prohibited	Disassembly is	KEEP FIRE AWAY	General instruction	Earth ground
	prohibited

CAUTION

(1) Product and manual

For items described as "Restrictions" or "Usable State" in this manual, the instruction manual issued by the machine tool builder takes precedence over this manual.

Items not described in this manual must be interpreted as "not possible".

This manual is written on the assumption that all option functions are added. Refer to the specifications issued by the machine tool builder before starting use.

Refer to the Instruction Manual issued by each machine tool builder for details on each machine tool.

Some screens and functions may differ depending on the NC system (or its version), and some functions may not be possible. Please confirm the specifications before use.

(2) Adjustments

Do not adjust or change the parameter settings greatly as operation could become unstable.

In the explanation on bits, set all bits not used, including blank bits, to "0".

(3) Troubleshooting

If the battery low warning is issued in the controller side, save the machining programs, tool data and parameters in an input/output device, and then replace the battery. When the battery alarm is issued, the machining programs, tool data and parameters may have been destroyed. Replace the battery and then reload the data.

If the battery low warning is issued in the drive unit side, immediately replace the battery. Replace the batteries while applying the drive unit's control power.

(4) Maintenance, inspection and part replacement

Do not short-circuit, charge, heat, incinerate or disassemble the battery. Dispose of the spent battery according to local laws.

1 Operation Errors (M)

M01	Dog overrun	0001
	Details

When returning to the reference position, the near-point detection limit switch did not stop over the dog, but overran the dog.

	Remedy
	Increase the length of the near-point dog.
	Reduce the reference position return speed.
M01	Some ax does not pass Z phase	0002
	Details

One of the axes did not pass the Z-phase during the initial reference position return after the power was turned ON.

Remedy

Move the detector one rotation or more in the opposite direction of the reference position, and repeat reference position return.

M01	R-pnt direction illegal	0003
	Details

When manually returning to the reference position, the return direction differs from the axis movement direction selected with the AXIS SELECTION key.

Remedy

The selection of the AXIS SELECTION key's +/- direction is incorrect. The error is canceled by feeding the axis in the correct direction.

M01	External interlock axis exists	0004
	Details

The external interlock function has activated (the input signal is "OFF") and one of the axes has entered the interlock state.

	Remedy
	As the interlock function has activated, release it before resuming operation.
	Correct the sequence on the machine side.
	Check for any broken wires in the "interlock" signal line.
M01	Internal interlock axis exists	0005
	Details

The internal interlock state has been entered.

The absolute position detector axis has been removed.

A command for the manual/automatic simultaneous valid axis was issued from the automatic mode. The manual speed command was issued while the "tool length measurement 1" signal is ON.

A travel command has been issued to an inclined axis whose base axis is in control axis synchronization across part systems.

Selected an axis other than the 1st axis when the manual speed command was issued. A travel command has been issued to an axis stopped by the collision detection function.

Remedy

The servo OFF function is valid, so release it first.

An axis that can be removed has been issued, so perform the correct operations.

The command is issued in the same direction as the direction where manual skip turned ON, so perform the correct operations.

During the manual/automatic simultaneous mode, the axis commanded in the automatic mode became the manual operation axis. Turn OFF the "manual/automatic valid" signal for the commanded axis.

Turn ON the power again, and perform absolute position initialization.

Turn OFF the "tool length measurement 1" signal to start the program by the manual speed command. Cancel the control axis synchronization across part systems, then issue a travel command to the inclined axis.

Select the 1st axis of each part system when issuing the manual speed command. Cancel the collision detection alarm.
