E1 Series Servo Drive User Manual Electrical Planning
HIWIN MIKROSYSTEM CORP. 5-3
Use the cables specified by HIWIN while wiring.
If cables which are not specified by HIWIN are used, perform wiring by using the wiring materials specified by
HIWIN or equivalent products after checking the rated current of the servo drive and environment.
Ensure the screws on cable connectors are tightened and the servo drive is securely installed inside the
control box.
If the screws are not tightened, the cable connectors could fall off during operation.
Do not put high power cables (such as main circuit power cable) and low power cables (such as I/O signal
cable and encoder cable) in the same cable tray or tie them together. If high power cable and low power cable
are not put in separate cable trays, they should be at least 30 cm apart.
If this is not followed, false operation may occur when low power cable is interfered.
Encoder battery must be installed on encoder cable.
While installing encoder battery, pay attention to its polarity.
A broken battery may cause encoder malfunction.
For a safe and stable servo system, the following must be followed while wiring.
(1) Use the cables specified by HIWIN. While designing and configuring a system, the cables must be
as short as possible.
(2) The conductors of signal cable must be 0.2 mm
2
or 0.3 mm
2
. Do not bend or apply tension to the
cable.
Circuit breaker or fuse must be applied to protect the main circuit.
If the servo drive is directly connected to a commercial power supply and is not
insulated by transformer or other device, circuit breaker or fuse must be used to
prevent the servo system from being affected by external system.
Earth leakage circuit breaker must be applied.
The servo drive has no protective circuit for ground fault. To have a safer system, it
is suggested to install earth leakage circuit breaker or earth leakage circuit breaker
with molded-case circuit breaker to prevent overload or short circuit.
Do not frequently turn on or turn off the power of the servo drive.
The internal components of the servo drive may be deteriorated if the power is
frequently turned on or off.
The interval between power on and power off must be at least one hour after
