Drive unit and peripheral devices
1.2.1 Peripheral devices
Check the drive unit model of the drive unit you purchased. Appropriate peripheral devices must be selected according to the
capacity.
Refer to the following list and prepare appropriate peripheral devices.
(1) S-PM geared motor

 Select an MCCB according to the power supply capacity.
 Install one MCCB per drive unit.

For the use in the United States or Canada, refer to "Instructions for UL and cUL" in the Instruction Manual (Basic),
and select an appropriate fuse or molded case circuit breaker (MCCB).

Magnetic contactor is selected based on the AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the magnetic contactor is
used for emergency stop during motor driving, the electrical durability is 25 times.
If using an MC for emergency stop during motor driving, select an MC regarding the drive unit input side current as JEM1038-AC-3 class rated current.

The power factor may be slightly lower.
NOTE

The life of the drive unit is influenced by surrounding air temperature. Pay attention to the surrounding air
temperature. This must be noted especially when the drive unit is installed in an enclosure.
(Refer to page 8.)
 Wrong wiring might lead to damage of the drive unit. The control signal lines must be kept fully away from the main
circuit to protect them from noise.
(Refer to page 14.)

Do not install a power factor correction capacitor, surge suppressor or noise filter (capacitor) on the drive unit output
side. This will cause the drive unit to trip or the capacitor and surge suppressor to be damaged. If any of the above
devices are connected, immediately remove them.
 Electromagnetic wave interference
The input/output (main circuit) of the drive unit includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the drive unit. In this case, install the FR-BIF optional noise
filter (capacitor) (for use in the input side only) or FR-BSF01 or FR-BLF noise filter (ferrite core) to minimize
interference.
(Refer to page 38.)

Refer to
the Instruction Manual of each option and peripheral devices
for details of peripheral devices.
 A PM motor cannot be driven by the commercial power supply.
 A PM motor is a magnet motor. High-voltage is generated at motor terminals while the motor is running even after the
drive unit power is turned OFF. Before closing the contactor on the output side, make sure that the drive unit power is
ON and the motor is stopped.
