3.4 Time Sequence Diagram of Control Signal
Precautions on Control Signal:
1. The maximum frequency
of the input pulse is 400
KHz.
2. Disable direction signal
change during pulse
signal rise time.
3. A free signal shall be set
up 1ms earlier than a
pulse signal.
Precautions on Wiring:
1. 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.
2. 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).
3. Due to endurance of heavy current, conductors with cross-section no less than
1.5mm
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.
4.
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.
5. 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.
