Thank you for choosing this Mitsubishi Sensorless servo drive unit.
This Instruction Manual (Applied) provides instructions for advanced use of the FR-E700EX series drive units.
Incorrect handling might cause an unexpected fault. Before using the drive unit, always read this Instruction Manual and the
instruction manual (Basic) [IB-0600506ENG] packed with the product carefully to use the equipment to its optimum performance.
1. Electric Shock Prevention
2. Fire Prevention
3.Injury Prevention
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the drive
unit until you have read through the Instruction Manual and
appended documents carefully and can use the equipment
correctly. Do not use this product until you have a full knowledge
of the equipment, safety information and instructions.
In this Instruction Manual, the safety instruction levels are
classified into "WARNING" and "CAUTION".
Incorrect handling may cause hazardous
conditions, resulting in death or severe
injury.
Incorrect handling may cause hazardous
conditions, resulting in medium or slight
injury, or may cause only material damage.
The level may even lead to a serious consequence
according to conditions. Both instruction levels must be
followed because these are important to personal safety.
While the drive unit power is ON, do not open the front cover
or the wiring cover. Do not run the drive unit with the front
cover or the 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 accidentally touch
the charged drive unit circuits and get an electric shock.
Before wiring or inspection, power must be switched OFF.
To confirm that, LED indication of the operation panel must
be checked. (It must be OFF.) Any person who is involved in
wiring or inspection shall 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 drive unit must be earthed (grounded). Earthing
(grounding) must conform to the requirements of national
and local safety regulations and electrical code (NEC section
250, IEC 536 class 1 and other applicable standards).
Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
The drive unit must be installed before wiring. Otherwise
you may get an electric shock or be injured.
Setting dial and key operations must be performed with dry
hands to prevent an electric shock.
Do not subject the cables to scratches, excessive stress, heavy
loads or pinching. Otherwise you may get an electric shock.
Do not change the cooling fan while power is ON. It is
dangerous to change the cooling fan while power is ON.
Do not touch the printed circuit board or handle the cables
with wet hands. Otherwise you may get an electric shock.
When measuring the main circuit capacitor capacity, the DC
voltage is applied to the motor for 1s at powering OFF. Never
touch the motor terminal, etc. right after powering OFF to
prevent an electric shock.
A PM motor is a synchronous motor with embedded magnets.
High-voltage is generated at motor terminals while the motor
is running even after the drive unit power is turned OFF.
Before wiring or inspection, the motor must be confirmed to
be stopped. For applications where the motor is driven by the
load, the low-voltage manual contactor, which is installed at
the drive unit's output side, must be opened before wiring or
inspection. Otherwise you may get an electric shock. Do not
use a magnetic contactor at the drive unit's output side.
WARNING
CAUTION
CAUTION
WARNING
Drive unit must be installed on a nonflammable wall without
holes (so that nobody touches the drive unit heatsink on the
rear side, etc.). Mounting it to or near flammable material
can cause a fire.
If the drive unit has become faulty, the drive unit power must
be switched OFF. A continuous flow of large current could
cause a fire.
When using a brake resistor, a sequence that will turn OFF
power when a fault signal is output must be configured.
Otherwise the brake resistor may overheat due to damage of
the brake transistor and possibly cause a fire.
Do not connect a resistor directly to the DC terminals P/+
and N/-. Doing so could cause a fire.
Daily and periodic inspections must be performed as
instructed in the Instruction Manual. If the product is used
without receiving any inspection, it may cause a burst,
break, or fire.
The voltage applied to each terminal must be the ones specified in
the Instruction Manual. Otherwise burst, damage, etc. may occur.
The cables must be connected to the correct terminals.
Otherwise burst, damage, etc. may occur.
Polarity must be correct. Otherwise burst, damage, etc. may
occur.
While power is ON or for some time after power-OFF, do not
touch the drive unit as they will be extremely hot. Doing so
can cause burns.
