PPC-HDD(MS)A User’s Guide

CONTEC CO.,LTD.

Thank you for purchasing the PPC-HDD(MS)A hard disk unit for PC CPU Module. Follow the
instructions in this guide to use the product.

Notes!

- The hard disk drive can be easily damaged by electrostatic discharge (ESD). Use meticulous care
in handling the hard disk unit for moving or assembling.

- When using the hard disk unit, be sure to satisfy the conditions listed as its general specifications.
For use in a severe environment, use the silicon disk unit instead.

- For use in a place subject to vibration or shock, use a set of shock-proof brackets [PPC-HBR-01]
available as an option.

- As the hard disk unit has a limited life, be sure to back up important data recorded on the unit.
To back up the contents of the hard disk, including the OS, you should use a commercial backup tool
(such as Symantec Ghost).

- The hard disk drive (HDD) of this disk unit has not guaranteed use by continuation and continuation
power for 24 hours. When it is used by continuation operation and continuation power a life falls
extremely. In the case of a 24-hour operation system, use of our company silicon disk (SDD) is
recommended.

The life of a hard disk drive changes with environment or operating conditions. As a

-

standard, power time (motor-on time) below 333hours/month (below 11 hours/day), disk
access time is 20% or less, it becomes which for 20,000 hours (power time) or five years,
or an early thing.

- Do not touch the interface connector of the hard disk unit.

- Before plugging to or unplugging from the connector on the hard disk unit, be sure to turn off the
power unit.

- CONTEC assumes no liability for any loss or destruction of data recorded by this product regardless
of the attribute of the causing fault or failure. Be sure to back up important data.

Installing the Hardware

Precautions
Install the hard disk unit on the MELSEC-Q Series base unit before it can be used.

Before using the hard disk unit, be sure to mount the MELSEC-Q Series base unit on the control panel
using screws. Do not use the base unit mounted on the DIN rail.
For mounting the base unit, refer to the “Mitsubishi General-purpose Sequencer QCPU (Q Mode) User’s
Manual (Hardware Design, Maintenance and Inspection)”.
Device is to be powered by limited Voltage/Current circuit of Listed Power Supplies,
Models : Q61P-A1, Q61P-A2, Q61P, Q63P, Q64P, manufactured by Mitsubishi Electric Corp.

Fastening the Hard Disk Unit

- Fit the unit fixing hook in the unit fixing slot in the base unit, then push the hard disk unit in the
direction of the arrow to set the hard disk unit on the base unit

Unit fixing slot

Unit fixing hook

- After setting the hard disk unit on the base unit, be sure to use the attached unit fixing screw to fasten
the hard disk unit to the base unit.

- Tighten the screw within the following torque range.

Tightening torque range: 36 - 48N·cm

If the hard disk unit may be subject to vibration between 4.9 and 9.8 m/s2, use a set of hard disk unit
shock-proof brackets [PPC-HBR-01] available as an option. For installing the base unit with the hard
disk unit on the control panel, refer to the manual for the shock-proof brackets.

Average Life of the Hard Disk Drive

The average life of the hard disk drive is 5 years or 20,000 hours of energized time whichever reached first.

High-temperature Detection Feature

Using the hard disk unit in a high-temperature environment shortens the life of the hard disk. The hard
disk unit has a high-temperature detection feature to detect an ambient operating temperature of 47±3°C
or higher using the high-temperature detection function of bus interface driver software. Use this feature
as a means of warning when the hard disk unit is being used at high temperature.

When high-temperature detection is not necessary, you can disable the high-temperature detection
function by setting with the bus interface driver software. In that case, high-temperature detection is not
performed.

For details on this function, refer to the Bus Interface Driver User's Manual [PPC-CPU686(MS)-MU or
PPC-CPU852(MS)-MU, separately priced].
