3.2.2 Wiring diagram of three phase 230V/400V
·
Input voltage range of 220V system:
AC 220V(-15%)~240V(+10%)
·
Input voltage range of 400V system:
AC 380V(-15%)~440V(+10%)
·
Do not disconnect the short circuit
wire between B2 and B3 unless an
external regenerative braking
resistor is used.
·
When an external regenerative
braking resistor is used, disconnect
the short circuit wire between B2 and
B3, and connect it according to the
dotted line in the figure.
·
Connect the output U, V and W of
the drive to the servo motor correctly
according to the phase sequence of
the motor cable of the servo motor.
Wrong phase sequence will cause
drive fault.
·
Be sure to ground the servo drive to
avoid accident of electrical shock.
·
The electromagnetic brake uses 24V
power supply which should be
provided by the user. Moreover, it
must be isolated with the DC12-24V
power supply which is used by the
control signal.
·
Pay attention to the connection of the
freewheeling diode. Reversed
polarity may damage the drive.
·
The user is required to make this
emergency stop protection circuit.
·
Add surge absorbing devices on both
ends of the electromagnetic
contactor winding.
