2. LINEAR SERVO MOTOR
2. LINEAR SERVO MOTOR
The secondary side of the linear servo motor contains a strong permanent magnet. The wrong handling may
cause serious accidents, which is extremely dangerous. Please read this chapter carefully beforehand and use
it correctly.
2.1 Handling
2.1.1 General instructions
WARNING
The linear servo motor uses a strong magnet on the secondary side. Therefore,
not only the linear servo motor installation operators but also the machine
operators must use abundance of caution. For example, one who uses a medical
device like a pacemaker must keep away from the machine.
The permanent magnet on the secondary side makes the magnetic bodies
generate suction. Use caution with accidents so as not to get your hand stuck.
The performance is not guaranteed if the specified servo amplifier and linear
servo motor are not combined. If used with unspecified combination, the servo
amplifier or linear servo motor may be damaged. Depending on the case, it can
be out of control and fall into the extremely dangerous condition such as runaway.
CAUTION
The linear servo motor installation operators and machine operators must not
work wearing electronic devices (watch, calculator, personal computer, etc.) and
magnetic recording media (IC card, magnetic card, floppy disc, etc.) and must not
bring them around a magnetic. The magnetic influence may cause the operation
failure or malfunction.
The protection method of the linear servo motor is IP00. Take necessary
measures against dust, oil, etc. (Refer to Section 2.1.2 Installation direction.)
When the linear servo motor is damaged, it must be replaced. Contact Mitsubishi
Electric System & Service Co., Ltd.
When the protective function is operated, turn the power off immediately to
eliminate its cause, and then turn it on again. If the linear servo motor is continued
operating without eliminating the cause, it may run out of control or malfunction,
which may cause a damage and injury.
Take safety measures, e.g. provide covers, to prevent accidental contact of
hands and parts (cables, etc.) with the servo amplifier heat sink, regenerative
brake resistor, linear servo motor, etc. since they may be hot while power is on or
for some time after power-off. Their temperatures may be high and you may get
burnt or a parts may damaged.
The primary side (coil) and secondary side (magnet) may be damaged by a fall or
shock.
