YASKAWA JUNMA SERIES User Manual

17
•
Only an electrical engineer should perform the wiring.
•
Design the circuit so that both the /S-ON signal and the main-circuit power supply turn
OFF at an emergency stop.
•
An overtravel function is not provided for the SERVOPACK. To configure a safer
system, include a function so that the /S-ON signal will turn OFF when the limit switch
is activated.
•
If the servomotor is used to drive a vertical axis, install a safety device such as a
counterweight to prevent the workpiece from falling down when an alarm occurs.
Failure to observe this precaution may result in injury or damage to the equipment
from fallen workpieces.
•
Use a molded-case circuit breaker and fuse to protect the power supply line from high
voltage. The SJDE SERVOPACK connects directly to a commercial power supply
without a transformer, so always use a circuit breaker and fuse to protect the
SERVOPACK from accidental high voltage.
•
The ground protection circuit is designed for ground fault inside the motor windings
while the motor is running. Therefore, it may not protect the system under the
following conditions.

A low-resistance ground fault occurs between the main circuit cable and connector
for the servomotor.

The power supply is turned ON during a ground fault.
To configure a safer system, install an earth leakage breaker to protect against both
overloads and shortcircuits, or install an earth leakage breaker for ground protection
and a molded-case circuit breaker.
•
The distance between a power line (such as a power supply line or servomotor cable)
and a signal line must be at least 30 cm. Do not put the power and signal lines in the
same duct, and do not bundle them together.
•
The longer a pulse line is, the lower the maximum frequency of the line is.
•
Customers must purchase a 24 VDC power supply with double-shielded enclosure.
•
Install an interlock system in the circuit to avoid any accident when opening or closing
the machine’s protective cover.
• To
ground a SERVOPACK, follow these conditions.

Use as thick a cable as possible (HIV 2.0 mm
2
or thicker) for grounding.

A ground resistance of 100
Ω
or less is recommended.

Ground to one point only.

Wiring Precautions
Caution for Grounding
•
For wiring, use the specified cables. Use cables that are as short as possible.
•
Do not bend exessively or apply tension to cables. The conductor of a signal cable is
very thin (0.08 to 0.12 mm
2
), so handle the cables carefully.
