Safety Precaution
First thank you for using our iS7 Synchonization Option Board!
Please follow the following safety attentions since they are
intended to prevent any possible accident and danger so that you
can use this product safely and correctly.
Safety attentions may classify into ‘Warning’ and ‘Caution’ and their
meaning is as following:
Symbol
Meaning
WARNING
This symbol indicates the possibility of death or
serious injury.
CAUTION
This symbol indicates the possibility of injury or
damage to property.
The meaning of each symbol in this manual and on your equipment
is as follows.
Symbol
Meaning
This is the safety alert symbol.
Read and follow instructions carefully to avoid
dangerous situation.
This symbol alerts the user to the presence of
“dangerous voltage” inside the product that might
cause harm or electric shock.
After reading this manual, keep it in the place that the user always
can contact. This manual should be given to the person who
actually uses the products and is responsible for their maintenance.
WARNING
Do not remove the cover while power is applied or the unit is in
operation.
Otherwise, electric shock could occur.
Do not run the inverter with the front cover removed.

1 Installation Conditions
iv
WARNING
Otherwise, you may get an electric shock due to high voltage terminals or
charged capacitor exposure.
Do not remove the cover except for periodic inspections or wiring,
even if the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
Wiring and periodic inspections should be performed at least 10
minutes after disconnecting the input power and after checking the
DC link voltage is discharged with a meter (below DC 30V).
Otherwise, you may get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use the cable when its insulating tube is damaged.
Otherwise, you may get an electric shock.
Do not subject the cables to scratches, excessive stress, heavy
loads or pinching.
Otherwise, you may get an electric shock.
CAUTION
Be cautious when handling CMOS elements on the option board.
It may cause a failure due to static electricity.
When changing and connecting communication signal lines,
proceed the work while the inverter is turned off.
It may cause a communication error or failure.
Make sure to connect the inverter body to the option board
connector accurately coincided each other.
It may cause a communication error or failure.
Make sure to check the parameter unit when setting parameters.
It may cause a communication error.

Performance Standard
Position Sync
Within ±5 degree, the deviation in position between
the master and the slave during steady-state
operating under the rated load.
Speed Sync
Within a bigger value between ±0.5% and ±5rpm, the
deviation in speed between the master’s order speed
and the slave’s current speed during steady-state
operating under the rated load. (Note2)
Table 3 Performance Standard
(Note2) For example, if the speed of the master’s command is 1800rpm, the
maximum deviation between the speed of the master’s command and the one of the
slave’s command shall be within ±9rpm (=±0.5%). In addition, if the master’s
command speed is 500rpm, the maximum deviation between the speed of the
master’s command and the one of the slave’s command shall be within ±5rpm since
±2.5rpm (=±0.5%) is smaller than ±5rpm.

3. Installation
Step 1
Remove the cover and mount an encoder option card (slot 3) and a
synchronization option card (slot 2) as seen in the figure below. But,
if any inverter is used as the master for the synchronization
operation, the master inverter does not need any synchronization
option card to be mounted (Refer to Step 2).
Step 2
Wire the encoder option card (slot 3)and the synchronization option
card (slot 2) as seen in the figure below. The following figure shows
a wiring example of the case where the master motor’s encoder is
of 5V line driver type and the slave motor’s encoder is of 15V open
collector type.
1. Remove the
cover
2. Mount an encoder card
to slot 3
3. Mount an encoder card
to slot 2
