The servo amplifier must be installed in the metal cabinet.
When fumigants that contain halogen materials such as fluorine, chlorine, bromine, and iodine are used for
disinfecting and protecting wooden packaging from insects, they cause malfunction when entering our
products. Please take necessary precautions to ensure that remaining materials from fumigant do not
enter our products, or treat packaging with methods other than fumigation (heat method). Additionally,
disinfect and protect wood from insects before packing products.
(2) Wiring
Before unplugging CNP1 connector from the servo amplifier, disconnect the lead of the built-in
regenerative resistor from CNP1 connector first.
Wire the equipment correctly and securely. Improper wiring may cause unexpected operation.
Do not install a power capacitor, a surge killer or a radio noise filter (optional FR-BIF) between the servo
motor and the servo amplifier.
Connect the wires to the correct phase terminals (U, V, W) of the servo amplifier and the servo motor. Not
doing so may cause unexpected operation.
Connect the servo amplifier power output (U/V/W) to the servo motor power input (U/V/W) directly. Do not
install a magnetic contactor, etc. between the servo amplifier and the servo motor.
Servo amplifier
Do not connect AC power supply directly to the servo motor. Otherwise, a fault may occur.
Install a surge absorbing diode on the DC relay designed for control output signal in the specified
direction. Improper installation of the surge absorbing diode may cause the servo amplifier to malfunction
such that the signals are not output, and emergency stop and other safety circuits are inoperable.
Configure a circuit to turn off EM1 when the main circuit power supply is turned off to prevent an
unexpected restart of the servo amplifier.
(3) Test run adjustment
Check and adjust the parameter setting before operation. Improper settings may cause some machines
to perform unexpected operation.
Never adjust or change the parameter values extremely as it will make operation unstable.
