 Do not open the cover while the power is on or at any time during operation.
Doing so may result in an electric shock.
 Do not operate the inverter while the cover is open.
Exposing the high voltage terminal or charging area to the external environment may
result in an electric shock.
 Do not open the cover even when the power supply has been switched off. This
excludes necessary maintenance or regular inspection.
Opening the cover may result in an electric shock even if the power supply is off. The
inverter may hold a charge long after the power supply has been switched off.
 Do not conduct maintenance or inspection without first ensuring that the DC
voltage of the inverter has been fully discharged. To ensure this, use a voltage
tester at least ten minutes after the power supply has been cut off.
Doing so may result in an electric shock. (DC 30 V or less)
 Do not operate switches on the inverter with wet hands.
Doing so may result in an electric shock.
 Do not use the inverter if the cable has been damaged.
Doing so may result in an electric shock.
 Do not place heavy objects on the cable.
Placing heavy objects on the cable could damage its sheath and may result in an
electric shock.
Caution
 Do not install the product near any flammable materials.
Mounting the inverter on or near flammable materials may start a fire.
 Switch off the power supply to a faulty inverter.
Failure to switch off the power supply to a faulty inverter may start a fire.
 Do not touch the inverter while the power supply is on or within ten minutes of
switching the power supply off.
Touching the inverter during this period may result in a burn due to the high operating
temperatures of this product.
 Do not supply power to a faulty inverter even after it has been installed.
Doing so may result in an electric shock.
 Make sure that foreign substances, such as screws, metal, water, and oil, do not
enter the inverter.

If you use a product with a built-in braking resistor (capacity = less than 3.7 kW),
make sure that PRT67 [DB RES SEL] is set to “Inside” and PRT66 [DB
Warn %ED] is set to 1 or 2 percent.
If [DB Warn %ED] is 0%, it means that there is no limit on the use of the braking
resistor. Continuously using the braking resistor in an environment that requires
frequent braking may burn out the braking resistor.
Moreover, for products with a built-in braking resistor, [DB Warn %ED] can be set
to 2% to limit capacity and protect the braking resistor. For environments that
require frequent braking, please select a product without a built-in braking
resistor and use a separate braking resistor.
2% usage means that, if the braking operation conditions are sustained for 100
seconds, braking is activated for 2 seconds only and is deactivated for the
remaining 98 seconds even under braking operation conditions.
Products with a built-in braking resistor can continuously operate the braking
resistor for 5 seconds. Thus, if the braking operation conditions are maintained,
braking is activated for 5 seconds but is deactivated for the next 245 seconds
even under braking operation conditions. Therefore, if the braking operation is
interrupted, the braking resistor is unavailable for at least 245 seconds (when set
at 2%).

2. Winder/Unwinder Operation
2-1
2. Winder/Unwinder Operation
2.1 Overview
Winders are also called “spoolers”. These components wind up web material
(iron wire, iron plate, steel wire, etc) as they maintain a constant tension in the
material. In contrast to this, unwinders unwind web material, as they maintain a
constant tension in the material.
Basically, the winder and unwinder in an iS7 inverter use analog feedback from
the tension control detectors, such as the dancer or load cell, to activate the PID
controller and maintain a constant tension. This way, the winder and unwinder
form a closed loop tension control system when winding and unwinding web
material. In addition, the characteristics of the PID controller in the closed loop
tension control system differ from existing PID controllers. That is why this
system is referred to as a “Web PID controller” in this manual.
However, even open loop tension control systems that do not use a Web PID or
tension control detectors like dancers and load cells can function using the
winder and unwinder from an iS7 inverter.
The tension control operation of an iS7 inverter can be broadly subdivided into
the winder/unwinder, closed loop/open loop, and speed/tension command
operations.

The actual diameter (m) of the winder increases during operation. As shown in
Eq. 1.1.1, the motor speed (rpm) decreases as the diameter of the winder
increases to maintain a constant flux (mpm). The motor speed, i.e. output
frequency of the inverter, is reduced by activating the Web PID controller. In
addition to this, the Web PID controller computes and estimates the increases to
the diameter of the winder internally and uses the computed diameter ultimately
to decrease the output frequency of the inverter.
In contrast to the winder, the actual diameter (m) of the unwinder decreases
during operation. As shown in Eq. 1.1.1, the motor speed (rpm) increases as the
diameter of the winder decreases to maintain a constant flux (mpm). In a closed
loop tension control system, this motor speed, i.e. the output frequency of the
inverter, is increased by activating the Web PID controller. In addition to this, the
Web PID controller computes and estimates the decreases to the diameter of the
winder internally and uses the computed diameter ultimately to increase the
output frequency of the inverter.
This system offers more consistent control over the winder tension than
conventional PID controllers. Since the internally computed diameter
compensates for the inverter's output frequency once again, the Web PID
controller uses significantly less of the inverter's output frequency. Therefore, the

2. Winder/Unwinder Operation
2-2
Web PID controller does not risk saturating the output, which is effective in
significantly reducing the oscillation of the I controller output.
The Web PID controller also offers the following functions:
 Eliminates the transient phenomenon that occurs with the dancer or load
cell at start up (related code: APP51).
 Compensates for the inertia of the winder (related code: APP56-57).
 Maintains the tension and, if necessary, performs an emergency stop
(related code: APP82).
 Detects potential ruptures in the web material in advance (related code:
APP76-80).
You must comply with the following settings to ensure that the iS7 properly uses
the winder (spooler) or unwinder, or applies them to the closed or open loop
system.
