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.

2.4. Direction of and space for installation
Notes:
The direction for installation must conform to the specifications to prevent malfunction.
To ensure the cooling circulation remains effective, it is required to keep a sufficient space
between the upper, lower, left and right sides of the servo drive and the object and guard plate
(wall) nearby for the installation of the AC servo drive. If not, it may cause breakdown.
Do not seal the air inlet and outlet of the servo drive during installation or tilt the servo drive,
otherwise it may result in malfunction.
Drive installation:
The ISA-7 series server drive must be installed vertically on a dry and stable platform complying
to the NEMA standard. To ensure the circulation of ventilation air and heat radiation remain
effective, it is required to keep a sufficient space between the upper, lower, left and right sides of
the servo drive and the object and guard plate (wall) nearby for the installation of the AC servo
drive. (It is recommended to leave a free space of 50 mm, which is about 2 in.) Leave the space
required for wiring, if necessary. Besides, the bracket or platform for drive installation must be
made of materials with great thermal conductivity to prevent the platform and drive from
overheating.

We hope that the EMI filter elaborates the maximum suppression against the interference from the
servo drive. Therefore the servo drive must be installed and wired according to the manual.
Furthermore, the following must be noted:
1. The servo drive and EMI filter must be installed on the same metal surface.
2. For the installation of the servo drive and EMI filter, the servo drive should be installed above the
EMI filter, if possible.
3. The wiring must be as short as possible.
4. Adequate earthing is required for the metal surface.
5. The metal case or earth of the servo drive and EMI filter must be fixed firmly to the metal surface.
The contact surface between the metal case or earth and the metal area must be as large as
possible.
Selection of and installation notes for the motor wire
The selection and installation of the motor wire are associated with whether the EMI filter can
elaborate the maximum suppression against the interference from the servo drive. Note the following:
1. The cable with copper mesh for separation must be used (double separation preferred).
2. The copper mesh for separation on both ends of the motor wire must be grounded with shortest
distance and largest contact area.

The protective paint on the area where the U-shaped bracket for the metal pipe is fixed to the metal
surface needs to be removed to ensure that the contact is effective. Refer to the figure as follows.
3. The copper mesh for separation of the motor wire must be connected adequately to the metal
surface. The U-shaped bracket for the metal pipe should be used to fix the copper mesh for
separation at both ends of the motor wire to the metal surface. See the figure below for the correct
connection.
2.7. Selection for the regenerative resistor
If the output torque and rotating speed are in opposite directions, the energy is transmitted from the
loading end into the drive. The energy entered the capacitor of the DC bus so that the voltage of the
capacitor increases. The energy recharged can only be consumed by the regenerative resistor when the
voltage rises to a certain value. The regenerative resistor is included in the drive and available for
external connection.
The table below lists the specifications of the regenerative resistor offered by the ISA-7 series.

It is set for prevention of the drive
damage due to excessive amount of
instantaneous current caused by switch
turning or short circuit.
When an alarm occurs, the magnetic contactor can
be used with the servo drive to output the alarm
(ALRM) signal to control the magnetic contactor
(MC) to disconnect the power supplied to the servo
drive.
Use a proper EMI filter
and a correct installation
method to diminish the
interference.
Regenerative resistor:
To prevent the
abnormality caused by
the braking of the servo
motor, use the external
regenerative resistor to
connect to the P+ and D
ends of the servo drive to
open the circuit. If using
the internal regenerative
resistor, short the circuit
for the P+ and D ends
and open the circuit for
the P+ and C ends.

Installation notes:
1. Make sure that the power supply and wiring for the R S T and L1 and L2 must be accurate.
2. Make sure that the phase sequence regarding the wiring for the servo motor output U V W is
correct. The motor will not work if the connection is wrong and an alarm will occur.
3. When using the external regenerative resistor, open the circuit for the P and D ends and connect
the external regenerative resistor to the P and C ends. When using the internal external
regenerative resistor, short the circuit for the P and D ends and open the circuit for the P and C
ends.
If using the external braking unit, connect P+ and P- of the braking unit to the P and N ends of the
servo motor. Open the circuit for the P and D ends, as well as the P and C ends.
4. For the alarm or emergency stop, use ALM or WARN output to disconnect the magnetic
contactor (MC) to cut off the power supply of the servo drive.

The following must be noted for wire connecting:
1. When the power is cut off, do not touch the six major power lines R, S, T and U, V, W. It is allowed
to touch the lines after the charging light goes off.
2. Keep the six major power linesR, S, T and U, V, W away from other signal cables. Try to keep the
distance above 30 cm.
3. For extending the connecting line for encoder CN2, use the twisted-pair signal cable with isolated
grounding. Keep the cable within 20 m. If its length exceeds 20 m, use the one with the wire diameter
twice larger than the current one to keep the signal level from excessive attenuation.
