DATA CONTROL

Setting Data

The parameter setfile is stored in the EEPROM on the main control brd.. This is non-volatile
memory and will not generally be lost when the drive is powered down. However, this data could be lost if
there is a brd. failure. If this data is lost, the drive will need to be re-commissioned. For this reason, it is
recommended that the parameter setfile data be backed up in a file stored on a personal computer. This
requires the use of the optional commissioning software. The software and training is available through
Toshiba.

FAULT AND RECOVERY

Cautions when Handling Fault

When a fault occurs, before resetting, understand the fault code. It may be unsafe to restart if a
component or motor has failed. Every effort should be made to determine the cause of the fault and to
correct any problems before attempting to restart the drive.
To do this, it is necessary to record and evaluate the phenomena and conditions of the fault in detail
from both electrical and mechanical standpoints. Collect as much data as possible on the following items to
determine the operation situation when the fault occurred.
1) Record the fault message (fault display) shown on the display/keypad at the moment the fault
occurred.
2) Collect Tracesave data with a PC. Visit our website at
support for information about Tracesave and where to send the file for analysis.
3) Operation different from ordinary operation
Check if there was anything that affected the input power supply of the equipment at the moment
the fault occurred (for example, powering-on of large-capacity equipment which is connected to the
common AC power supply or short-circuits, etc.).
4) Power failure
Check if the input power supply of the equipment was disconnected at the time of the fault (for
example, if the line of the AC power supply was switched or if the breaker was turned on or off).
5) Load condition
Check if the load was drastically changed at the time of the fault.
6) Operation
Check to see if any changes in the process or load machinery were made by the operator at the
time of the fault.
7) Installation environment
Check if there was any abnormal ambient conditions present in the electrical room at the time of the
fault or before the fault. (Fault of air-conditioner or ventilation system, water leakage into the room,
intrusion of dirt or chemicals, etc...)
8) Changes
Check if there were any recent changes to other equipment around the drive or load machinery.
For example, if some electrical work was carried out on or around the equipment.
9) Lightning
Check if there were any lightning strikes in the area.
10) Abnormal sound, odor
Check if there was any odor or abnormal sound around the equipment at the time of the fault or
after.
Understanding the conditions before and during the fault can help to determine whether the fault is
attributable to factors inside or outside of the drive. Further, this information becomes an important clue to
determine the cause of intermittent faults. It is important to keep a precise record.
