Preface
Thank you for purchasing our Remote Keypad "TP-E1."
The Remote Keypad allows you to remotely operate FRENIC-Mini series of inverters. Using this
remote keypad, you can perform the operations that are available on the built-in keypad on
FRENIC-Mini inverter, such as running and stopping the motor, monitoring the running status, and
setting the function codes.
In addition, you can perform "data copying": You can read function code data from an inverter, copy
(write) it into another inverter, or verify it.
To use the Remote Keypad, make sure that the FRENIC-Mini inverter is equipped with the RS485
Communications Card (OPC-C1-RS), and connect the two using an optional Remote Operation
Extension Cable (CB-5S, CB-3S, or CB-1S, depending on the distance).
This manual describes how to install the Remote Keypad and the "data copying." For other
operations that are common to the built-in keypad, refer to the FRENIC-Mini Instruction Manual
(INR-SI47-0791-E), Chapter 3.
Before installing and using the Remote Keypad, read through this manual in conjunction with the
FRENIC-Mini User's Manual and make yourself familiar with its proper use. Improper use may
prevent normal operation or cause a failure or reduced life of the inverter.

Failure to heed the information indicated by this symbol may
lead to dangerous conditions, possibly resulting in death or
serious bodily injuries.
Failure to heed the information indicated by this symbol may
lead to dangerous conditions, possibly resulting in minor or
light bodily injuries and/or substantial property damage.
Failure to heed the information contained under the CAUTION title can also result in serious
consequences. These safety precautions are of utmost importance and must be observed at all
times.
ii
Operation
• Be sure to install the terminal block cover before turning the power on. Do not remove the
cover during power application.
Otherwise electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause electric shock.
• If the retry function has been enabled, the inverter may automatically restart after tripping,
depending on its cause, causing the motor driven by it to start rotating. In designing a
system or a facility using the motor driven by the FRENIC-Mini, make sure that such
automatic restart would not cause any personal injury, damage to equipment, or other
unintended incidents.
•If the stall prevention function has been selected, the inverter may operate at an
acceleration/deceleration time or frequency different from the set ones. Design the
machine so that safety is ensured even in such cases.
Otherwise an accident could occur.
• The key is only effective when function setting (Function code F02) has been
established to enable the key. Prepare an emergency stop switch separately. If you
disable the STOP key priority function and enable command (FWD) or (REV), you cannot
stop the inverter output by the key on the built-in keypad.
• If an alarm reset is made with the operation signal turned on, a sudden start will occur.
Check that the operation signal is turned off in advance.
Otherwise an accident could occur.
• If you have selected "Active" as the mode of Restart after momentary power failure (F14 =
4 or 5), the inverter will automatically restart, causing the motor driven by it to start
rotating. In designing a system or a facility using the motor driven by the FRENIC-Mini,
make sure that safety is secured even in such instances.
• If you set the function codes wrongly or without completely understanding the instruction
manuals and the FRENIC-Mini User's Manual, the motor may rotate with a torque or at a
speed not permitted for the machine.
An accident or injuries could occur.
• Do not touch the inverter terminals while the power is applied to the inverter even if the
inverter stops.
Doing so could cause electric shock.
iii
Installation and cabling/wiring of option cards
• Do not operate the switch SW1 with wet hands.
Doing so could cause electric shock.
• Before starting installing the RS485 Communications Card, first turn off the power, wait
more than 5 minutes, and make sure, using a circuit tester or another appropriate
instrument, that the DC voltage between the P (+) and N (-) terminals of the main circuit is
less than +25 VDC.
Otherwise electric shock could occur.
• A high voltage is present just on the RS485 Communications Card. Do not remove the
cover for the control circuit terminal block (TB) while power is applied.
Doing so could cause electric shock.
• Generally, the sheath of control circuit wires is not reinforced by any insulation. If the
control circuit wires come into direct contact with the live main circuit terminal, therefore,
the sheath may break. Accordingly, there is a possibility that high voltage on the main
circuit may be applied to the control circuit wires. It is DANGEROUS. Be sure to keep the
control wires away from the live main circuit terminals.
An accident or electric shock could occur.
Disposal
•Handle this Remote Keypad or the RS485 Communications Card as an industrial waste
when disposing of it.
Otherwise injuries could occur.
Others
• Never attempt to modify the inverter.
Doing so could cause electric shock or injuries.

3-3
Conflict between the Remote Keypad and the built-in keypad on the FRENIC-Mini
When a Remote Keypad is connected to the FRENIC-Mini, the built-in keypad on the
FRENIC-Mini is automatically disabled to avoid conflicts between them, with the following
exceptions (for safety considerations).
When keypad operation is enabled (F02 = 0, 2, or 3) and the STOP key priority is selected
(H96 = 1 or 3), the key on the FRENIC-Mini is also enabled so that the FRENIC-Mini
can be stopped by either key. The key on the FRENIC-Mini is also enabled to
perform an alarm reset.
In any event, the 7-segment LED monitor on the FRENIC-Mini displays the same
information as that on the Remote Keypad.
3.3 Data Copying
Menu #7 of "Data copying" allows you to read function code data out of FRENIC-Mini inverter (for
which function codes have already been set up), to store the function code data block into another
inverter, or to verify function code data. That is, this function compares the function code data saved
in the Remote Keypad with that stored in the inverter.
The following conditions and restrictions apply to data copying:
Some function code data cannot be copied (stored) into another inverter.
For safety considerations, some function code data cannot be copied to another inverter if the
specifications of the destination inverter are different from those of the source inverter. Which
function code data can or cannot be copied is summarized in the FRENIC-Mini Instruction Manual
(INR-SI47-0791-E), Chapter 5, the "Data copy" column of Section 5.1 "Function Code Tables," using
the following designations:
Y : Can be copied unconditionally.
Y1 :Cannot be copied if the rated capacity differs from the source inverter.
Y2 :Cannot be copied if the rated input voltage differs from the source inverter.
N : Cannot be copied in any situation. （The function codes marked with N cannot be verified,
either.
Set up manually function code data that cannot be copied individually as necessary, by using Menu
#1 "Data setting" in Programming mode.
If you cannot copy function code data:
Check whether the "E" or "CPE " indicator is blinking.
(1) "E" is blinking ("Write error"): The following cases can be thought of:
• The memory of the Remote Keypad contains no data. (You have not read the memory since
delivery or you have aborted a data read operation.)
• The memory of the Remote Keypad contains some invalid or abnormal data.
• The destination inverter type differs from the source inverter type.
• A write operation has been performed while the inverter is running.
• The inverter is in data protection mode.
• The "Enable editing of function code data from keypad" command (WE-KP) is off.
(2) "CPE " is blinking: The following cases can be thought of:
• The function codes stored in the Remote Keypad are not compatible with those stored in the
inverter. Non-standard function code data may have been stored, or the inverter may have
been upgraded in an incompatible manner. Consult your Fuji Electric sales office.
3-4
Figure 3.2 shows the transition flow between different states of the inverter during data copying
operation, while Table 3.4 shows details of the data copying functions. The memory of the Remote
Keypad can save function code data for one inverter.
Figure 3.2 Status Transition during Data Copying

Basic key operation
If you cannot access all the menus, set function code E52 to "2" ("Full-menu mode").
(1) On the initial menu, select "Data copying" by pressing the key or key several times until
"7.CPy "is displayed.
(2) Press the
key to switch to the List of data copying functions (for example, " EAd "for a
read operation).
(3) Select the desired function by using the key and key and press the key. The
specified function will be carried out (for example, "EAd "will blink).
(4) When the specified function is successfully completed, "E d " is displayed. To return to the List
of data copying functions or the initial menu, press the key once or twice, respectively.
Table 3.4 Data Copying Functions
LED
monitor
display Function Description
EAd Read data Reads function code data from the inverter and saves it into the memory of
the Remote Keypad.
Pressing the key during the read operation (while " EAd "is blinking)
aborts the read operation, causing "E" to blink on the LED monitor (see
Note) and the memory of the Remote Keypad to be cleared.
CoPy Copy data Writes the data stored in the memory of the Remote Keypad into the inverter.
Pressing the key during the write operation (while "CoPy " is blinking)
aborts the write (copy) operation, causing "E" to blink on the LED monitor
(see Note) and function code data in the inverter memory to be incompletely
modified. Do not run the inverter in such a state. Retry the write operation or
initialize the inverter data.
If you cannot perform a write (copy) operation, see "If you cannot copy
function code data": on page 3-3.
UE Verify data Compares the function code data stored in the memory of the Remote
Keypad with that stored in the inverter. If any discrepancy is found, the
verification is terminated, and the function code for which the discrepancy is
found starts blinking on the LED monitor. Pressing the key skips this
function code; pressing it for the second time resumes the verification from
the next function code.
Pressing the key during the verification (while "UE " is blinking)
aborts the verification, causing "E" to blink on the LED monitor (see Note).
"E" is displayed also when there is no function code data in the memory of
the Remote Keypad (see Note).
(Note) If "E"or "CPE " appears and blinks, press the key to clear it.

Notes in data copying
•Do not disconnect the Remote Keypad from the inverter during data copying.
If you do so, the following problems will arise with the Remote Keypad and/or inverter depending
upon the actual operation being in progress. Take the necessary action, following the instructions
below.
If a data read operation (EAd ) was in progress:
The operation in progress is terminated. The read data stored in the memory of the Remote Keypad
becomes invalid (the original data is lost). Data write and verify operations thereafter will result in a
blinking "E" display. Mount the Remote Keypad again and retry the read operation.
If a write operation (CoPy )was in progress:
The operation in progress is terminated. The function code data in the inverter memory is incompletely
modified. Do not run the inverter in such a state. Mount the Remote Keypad again and retry the write
operation or initialize the inverter data.
If a verify operation (UE ) was in progress:
The operation in progress is terminated.
If there is no data or abnormal data stored in the memory of the Remote Keypad, the "E" blinks on the
monitor.
•If an error occurs in communication between the Remote Keypad and inverter during data copying,
the "- - - -" appears on the monitor and the following problems will arise with the Remote Keypad
and/or inverter depending upon the actual operation being in progress. Take the necessary action,
following the instructions below.
If a data read operation (EAd )was in progress:
The operation in progress is terminated and "- - - -" appears on the monitor. Once the read operation is
terminated, the read data stored in the memory of the Remote Keypad becomes invalid (the original data
is lost). Data write and verify operations thereafter will result in a blinking "E" display.
When the communications error is removed, the Remote Keypad automatically enters the Running
mode. So, retry the read operation at this point.
If a write operation (CoPy )was in progress:
The operation in progress is terminated and "- - - -" appears on the monitor. The function code data in
the inverter memory is modified incompletely. Do not run the inverter in such a state.
When the communications error is removed, the Remote Keypad automatically enters the Running
mode. So, retry the write operation or initialize the inverter data.
If a verify operation (UE ) was in progress:
The operation in progress is terminated and "- - - -" appears on the monitor.
When the communications error is removed, the Remote Keypad automatically enters the Running
mode.
