3. To prevent injury, note the following
CAUTION
Only the voltage specified in the Instruction Manual should be applied to each terminal, Otherwise, a burst,
damage, etc. may occur.
Connect the terminals correctly to prevent a burst, damage, etc.
Ensure that polarity ( , ) is correct. Otherwise, a burst, damage, etc. may occur.
The servo amplifier heat sink, regenerative resistor, direct drive motor, etc. may be hot while power is on
or for some time after power-off. Take safety measures, e.g. provide covers, to prevent accidental contact
of hands and parts (cables, etc.) with them.
During operation, never touch the rotor of the direct drive motor. Otherwise, it may cause injury.
4. Additional instructions
The following instructions should also be fully noted. Incorrect handling may cause a fault, injury, electric shock,
etc.
(1) Transportation and installation
CAUTION
Transport the products correctly according to their mass.
Stacking in excess of the specified number of products is not allowed.
Do not carry the direct drive motor by holding the cables, rotor, encoder or connector.
Do not hold the front cover to transport the servo amplifier. The servo amplifier may drop.
Install the servo amplifier in a load-bearing place in accordance with the Instruction Manual.
Do not get on or put heavy load on the equipment.
The servo amplifier and direct drive motor must be installed in the specified direction.
Leave specified clearances between the servo amplifier and cabinet inside walls or other equipment.
Otherwise, it may cause a malfunction.
Do not install or operate the servo amplifier and direct drive motor which has been damaged or has any
parts missing.
Do not block intake and exhaust areas of the servo amplifier. Otherwise, it may cause a malfunction.
Do not drop or strike servo amplifier or direct drive motor. Isolate from all impact loads.
Securely attach the direct drive motor to the machine. If you attach it insecurely, the direct drive motor may
come off during operation.
Measure a direct drive motor, and check the motor vibration level. A great vibration may cause the early
damage of a bearing, encoder, and brake. The great vibration may also cause the poor connector
connection or bolt looseness.
For the gain adjustment at the equipment startup, check the torque waveform and the speed waveform by
using a measurement device, and then check that no vibration occurs. If the vibration occurs due to high
gain, the vibration may cause the early damage of the direct drive motor.
Take safety measures, e.g. provide covers, to prevent accidental access to the rotor of the direct drive
motor during operation.
Never hit the rotor of the direct drive motor, especially when coupling the direct drive motor to the machine.
Otherwise, the encoder may malfunction.
