This instruction manual (basic) provides handling information and precautions for use of the equipment. Please forward this instruction manual (basic) to the end user.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the inverter until you have read through this instruction manual (basic) and appended documents carefully and can use the equipment correctly. Do not use the inverter until you have a full knowledge of the equipment, safety information and instructions. In this instruction manual (basic), the safety instruction levels are classified into "WARNING" and "CAUTION".
Assumes that incorrect handling may cause hazardous conditions, resulting in death or severe injury.
Assumes that incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause physical damage only.
Note that even the level may lead to a serious consequence according to conditions. Please follow strictly the instructions of both levels
because they are important to personnel safety.
1. Electric Shock Prevention
While power is on or when the inverter is running, do not open the front cover. Otherwise you may get an electric shock.m
Do not run the inverter with the front cover or wiring cover removed. Otherwise, you may access the exposed high-voltage terminals or the charging part of the circuitry and get an electric shock.
Even if power is off, do not remove the front cover except for wiring or periodic inspection.You may access the charged inverter circuits and get an electric shock.
Before starting wiring, inspection or switching EMC filter on/off connector, switch off the inverter power, check to make sure that the operation panel indicator is off, wait for at least 10 minutes after the power supply has been switched off, and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power off and it is dangerous.
This inverter must be earthed. Earthing must conform to the requirements of national and local safety regulations and electrical codes. (NEC section 250,
WARNING
CAUTION
CAUTION
WARNING
(2) Wiring
Do not install a power factor correction capacitor, surge suppressor or radio
noise filter on the inverter output side.
The connection orientation of the output cables U, V, W to the motor will affect the direction of rotation of the motor.
(3) Test operation and adjustment
Before starting operation, confirm and adjust the parameters. A failure to do so may cause some machines to make unexpected motions.
(4) Operation
When you have chosen the retry function, stay away from the equipment as it will restart suddenly after an alarm stop.
The key is valid only when the appropriate function setting(refer to page
71) has been made. Prepare an emergency stop circuit (power off,
mechanical brake operation for an emergency stop, etc.) and switch separately.
Make sure that the start signal is off before resetting the inverter alarm. A failure to do so may restart the motor suddenly.
The load used should be a three-phase induction motor only. Connection of any other electrical equipment to the inverter output may damage the inverter as well as equipment.
Do not modify the equipment.
Do not perform parts removal which is not instructed in this manual. Doing so
may lead to fault or damage of the inverter.
The electronic thermal relay function does not guarantee protection of the motor from overheating.

Power-off and magnetic contactor (MC)
2.5 Power-off and magnetic contactor (MC)
(1) Inverter input side magnetic contactor (MC)
On the inverter input side, it is recommended to provide an MC for the following purposes.
(
Refer to page 3 for selection.)
1)To release the inverter from the power supply when the inverter's protective function is activated or when the drive is not functioning (e.g. emergency stop operation).
2)
To prevent any accident due to an automatic restart at restoration of power after an inverter stop made by a power failure
3)The control power supply for inverter is always running and consumes a little power. When stopping the inverter for an extended period of time, powering off the inverter will save power slightly.
4)To separate the inverter from the power supply to ensure safe maintenance and inspection work The inverter's input side MC is used for the above purpose, select class JEM1038-AC3MC for the inverter input side current when making an emergency stop during normal operation.
REMARKS
Since repeated inrush current at powering on will shorten the life of the converter part (switching life is 100 million times), frequent on/off must be avoided. Turn on/off the inverter start controlling terminals (STF, STR) to run/stop the inverter.
• Inverter start/stop circuit example
As shown on the left, always use the start signal (ON or OFF across terminals STF or STR-PC) to make a start or stop.

Precautions for use of the inverter
2.6 Precautions for use of the inverter
The FR-F700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items.
(1) Use crimping terminals with insulation sleeve to wire the power supply and motor.
(2) Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.
(3) After wiring, wire offcuts must not be left in the inverter.
Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling mounting holes in an enclosure etc., take care not to allow chips and other foreign matter to enter the inverter.
(4) Use cables of the size to make a voltage drop 2% maximum.
If the wiring distance is long between the inverter and motor, a main circuit cable voltage drop will cause the motor torque to decrease especially at the output of a low frequency. Refer to page 12 for the recommended cable sizes.
(5) The overall wiring length should be 500m maximum.
Especially for long distance wiring, the fast-response current limit function may decrease or the equipment connected to the secondary side may malfunction or become faulty under the influence of a charging current due to the stray capacity of the wiring. Therefore, note the overall wiring length. (Refer to page 13.)
Precautions for use of the inverter
(13) If the machine must not be restarted when power is restored after a power failure, provide a magnetic contactor in the
inverter's input side and also make up a sequence which will not switch on the start signal. If the start signal (start switch) remains on after a power failure, the inverter will automatically restart as soon as the power is restored.
(14) Instructions for overload operation
When performing an operation of frequent start/stop of the inverter, increase/decrease in the temperature of the transistor element of the inverter may repeat due to a continuous flow of large current, shortening the life from thermal fatigue. Since thermal fatigue is related to the amount of current, the life can be increased by reducing bound current, starting current, etc. Decreasing current may increase the life. However, decreasing current will result in insufficient torque and the inverter may not start. Therefore, increase the inverter capacity to have enough allowance for current.
(15) Make sure that the specifications and rating match the system requirements.

Reset method of protective function
5 TROUBLESHOOTING
When an alarm (major failures) occurs in the inverter, the protective function is activated bringing the inverter to an alarm stop and the PU display automatically changes to any of the following error (alarm) indications. If your fault does not correspond to any of the following errors or if you have any other problem, please contact your sales representative.
Retention of alarm output signal ..................When the magnetic contactor (MC) provided on the input side of the inverter is
opened at the activation of the protective function, the inverter's control power will be lost and the alarm output will not be held.
Alarm display ........................................... When the protective function is activated, the operation panel display
automatically switches to the above indication.
Resetting method............................................When the protective function is activated, the inverter output is kept stopped.
Unless reset, therefore, the inverter cannot restart. (Refer to page 89.)
When the protective function is activated, take the corresponding corrective action, then reset the inverter, and
resume operation. Not doing so may lead to the inverter fault and damage.
Inverter alarm displays are roughly divided as below. (1) Error message
A message regarding operational fault and setting fault by the operation panel (FR-DU07) or parameter unit (FR­PU04/FR-PU07) is displayed. The inverter does not shut off output.

Stall prevention (overcurrent)
Description
During acceleration
When the output current of the inverter exceeds the stall prevention operation level (Pr. 22 Stall prevention operation level, etc.), this function stops the increase in frequency until the overload current decreases to prevent the inverter from resulting in overcurrent shut-off. When the overload current has decreased below stall prevention operation level, this function increases the frequency again.
During constant­speed operation
When the output current of the inverter exceeds the stall prevention operation level (Pr. 22 Stall prevention operation level, etc.), this function lowers the frequency until the overload current decreases to prevent overcurrent shut-off. When the overload current has decreased below stall prevention operation level, this function increases the frequency up to the set value.
During deceleration
When the output current of the inverter exceeds the stall prevention operation level (Pr. 22 Stall prevention operation level, etc.), this function stops the decrease in frequency until the overload current decreases to prevent the inverter from resulting in overcurrent shut-off. When the overload current has decreased below stall prevention operation level, this function decreases the frequency again.
