3.2.3 Wiring diagram of three phase 400V (medium power range: 7.5kW–55kW)
· Input voltage range of 400V system:
AC 380V(-15%)~440V(+10%)
· It is necessary to connect external
regenerative brake resistor between
terminal (+) and PB
· 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 from 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.
