INVT SV-DB100 Series, Operation Manual

Page: 28 / 171

The input voltage range of main circuit and
control circuit is 230V±15%
Correctly connect to output U, V, and W of the
drive according to the phase sequence of the
motor cable of the servo motor. Wrong phase
sequence will cause drive fault.
Do not disconnect the short circuit wire between
B2 and B3 unless an external regenerative
braking resistor is used.
When and external regenerative braking resistor
is used, disconnect the short circuit wire between
B2 and B3, and connect it according to the
dashed in the figure.
Be sure to ground the servo drive to avoid
accident of electrical shock.
Please refer to section 4.6 for connection of the
electromagnetic brake.
The electromagnetic brake uses 24V power
supply which should be provided by the user.
Moreover, it must be isolated with the 12-24V
power supply which is used for the control
signal.
Pay attention to the connection method of the
freewheeling diode. Reversed polarity may
damage the drive.
The user is required to make this emergency
stop protection circuit.
Fit surge absorbing devices on both ends of the
electromagnetic contactor winding.
