Safety precautions
The ISA-7 series is an open type servo drive that must be installed in a shielded control box for
operation. The drive uses precise feedback control and combines a digital signal processor (DSP) with
high-performance computing. It controls the IGBT to generate current output to drive the three-phase
permanent-magnet synchronous motor (PMSM) to achieve precise positioning.
The ISA-7 series can be used for industrial application. It is recommended to install it in the
distribution box specified in the manual. (The drive, filament and motor must be installed in an
environment that meets the minimum specifications for UL50 Type 1 or NEMA 250 Type 1.)
Acceptance inspection
The servo motor and drive must be used according to specified methods to avoid fire or
equipment breakdown.
Installation notes
It is prohibited to use the product in the place exposed to the steam, corrosive or flammable
gases, otherwise it may result in electric shock or fire.
Wiring notes
The earth terminal must be connected to Class 3 earthing (below 100Ω). Poor earthing may
cause electric shock or fire.
Do not connect the three-phase power supply to U, V and W motor output terminal;
otherwise it may result in personal injury or fire.
Secure the set screw of the power supply and motor output terminal, otherwise it may cause
fire.
Operation notes
Before the operation of the machinery equipment, the setting value must be adjusted
according to the user parameter of the machinery equipment. The machinery equipment
might lose control or breaks down if the setting value is not adjusted to the adequate setting
value.
Before the operation of the machine, check if the emergency button can be activated anytime
for shutdown.
It is prohibited to touch any motor part that is in rotation during motor operation, otherwise it
may result in personal injury.
To avoid accidents, separate the coupling from the belt of the machinery equipment and keep
them separate before the first commissioning.
When the servo motor and machinery equipment are connected and in operation, operating
error may result in the damage of the machinery equipment and occasional personal injury.
Strongly recommended: Test the operation of the servo motor under the unloaded condition
and connect the motor to the load afterwards to avoid danger.
Do not touch the radiator of the servo drive in operation, otherwise it may result in burn
injuries due to heat.
