Safety Precaution
(Read these precautions before use.)
This manual classifies the safety precautions into two categories:
and
.
Depending on the circumstances, procedures indicated by
may also cause severe injury.
It is important to follow all precautions for personal safety
Indicates that incorrect handling may cause hazardous conditions, resulting in death or
severe injury.
Indicates that incorrect handling may cause hazardous conditions, resulting in medium or
slight personal injury or physical damage.
DESIGN PRECAUTIONS
•
Install a safety circuit outside the PLC so that the entire system conservatively operates even if an
abnormality occurs in the external power supply or a failure occurs in the PLC.
If the safety circuit is installed inside the PLC, malfunction and erroneous output may cause accidents.
STARTUP AND MAINTENANCE
PRECAUTIONS
•
Do not touch any terminal while the FX
2N
-20GM positioning controller's power is on.
Doing so may cause electric shock or malfunctions.
•
Before cleaning or retightening terminals externally cut off all phases of the power supply.
Failure to do so may cause electric shock.
•
Use the battery for memory backup correctly in conformance to the FX
2N
-10GM, FX
2N
-20GM
HARDWARE PROGRAMMING MANUAL.
-
Use the battery only for the specified purpose.
-
Connect the battery correctly.
-
Do not charge, disassemble, heat, put in fire, short-circuit, connect reversely, weld, swallow or
burn the battery, or apply excessive forces (vibration, impact, drop, etc.) to the battery.
-
Do not store or use the battery at high temperatures or expose to direct sunlight.
-
Do not expose to water, bring near fire or touch liquid leakage or other contents directly.
-
Incorrect handling of the battery may cause heat excessive generation, bursting, ignition,
liquid leakage or deformation, and lead to injury, fire or failures and malfunctions of facilities
and other equipment.
•
Thoroughly read the manual, sufficiently confirming safety, then perform returning to the zero point
in the MANU/AUTO mode, jog operation, step operation or automatic operation.
An operation error may damage the machinery or cause accidents.
STARTUP AND MAINTENANCE
PRECAUTIONS
•
Turn off the power to the FX
2N
-20GM positioning controller before attaching or detaching the
memory board. If the memory board is attached or detached while the FX
2N
-20GM positioning
controller's power is on, the data in the memory may be destroyed, or the memory board may be
damaged.
•
Do not disassemble or modify the FX
2N
-20GM positioning controller.
Doing so may cause fire, equipment failures, or malfunctions.
For repair, contact your local Mitsubishi Electric distributor.
•
Turn off the power to the FX
2N
-20GM positioning controller before connecting or disconnecting any
extension cable.
Failure to do so may cause equipment failures or malfunctions.
•
Turn off the power to the FX
2N
-20GM positioning controller before attaching or detaching the
following devices.
Failure to do so may cause equipment failures or malfunctions.

2. Outline of the unit
The FX
2N
-20GM positioning controller (hereinafter call FX
2N
-20GM or 20GM) is a pulse chain output unit
that enables the positioning control of a stepping motor or a servo motor via the drive unit.
•
One FX
2N
-20GM can control 2 axes. (Linear interpolation and circular interpolation are available.)
•
Both dedicated positioning language (cod instructions) and sequence language (basic instructions
and application instructions) are available.
•
A pulse generator can be connected to each axis or one pulse generator can be connected to both
axes and switched as required. The manual pulse generators must be an open collector output type.
•
The zero return operation at each start can be omitted with a servo amplifier with the absolute position
(ABS) detection function.
•
The FX
2N
-20GM can be used alone.
When an FX

TRANSPORTATION AND STORAGE
PRECAUTIONS
•
When transporting the FX
2N
-20GM positioning controller incorporating the optional battery, turn on
the FX
2N
-20GM positioning controller before shipment, the BATT LED is OFF, and check the
battery life.
If the FX
2N
-20GM positioning controller is transported with the BATT LED on or the battery
exhausted, the battery-backed data may be unstable during transportation.
•
The FX
2N
