3.4 Time Sequence Diagram of Control Signal
Precautions on Control
Signal:
The maximum frequency of
the input pulse is 400 KHz.
Disable direction signal
change during pulse
signal rise time.
An offline signal shall be set
up 1ms earlier than a pulse
signal.
Precautions on Wiring:
To avoid interference on
the driver, the strong
current cables (phase wires
and power cables of the
driver) shall be isolated
from the weak current
cables (for a distance of at
least 10cm) when
connecting wires for the
driver.
It is recommended that the
twisted pairs be adopted
for control signal cables for the driver, and the shielding layer be grounded reliably (to
the true ground of the driver and equipment).
Due to endurance of heavy current, conductors with cross-section no less
than1.5mm
2
are recommended for the motor cabling, or even thicker ones as
appropriate.
Motor cabling put insulated terminals ,it can reduce the contact
resistance between motor and driver.
It is strictly forbidden to connect wires while the power is on; otherwise, it may
cause
equipment damage and personal injury. Please note that the power line of the
motor
still carries heavy current even if the motor is in the locked status. Pull out or
connect the wire forcibly may cause equipment damage and personal injury.
The length of bare wires at the inputs of the power line of the motor and the power
input cable of the driver shall be around 10mm; it may result in poor contact if the
length is too short and may cause electric shock if the length is too long.
