Digital Brushless AC servo drive system - Ref.0707 MCSi-17/84
Connectors
Power terminals
Connector X4
 POWER INPUTS (L1, L2): Mains input terminals.
 POWER OUTPUTS (U, V, W): Output terminals for the voltage applied to
the motor. Current control with PWM on a carrier frequency of 8 kHz. When
connecting to the motor, watch the matching of phases U-U, V-V and W-W.
Connector X9
 L+, Ri, Re: Terminals to configure and connect the external ballast resistor.
Connector X5
 CONTROL POWER INPUTS ( L1, L2, GROUND): Input terminals for the
voltage supply of the drive's control circuits from mains. The maximum
cable section at these power terminals is 2.5 mm
2
.
 ACTIVATION OF THE INTERNAL FAN: The internal fan that cools the
drive's power elements starts when enabling the Drive_Enable signal (only
on models with integrated fan). It will stop when the heatsink temperature
is lower 70 °C since the Drive_Enable signal is turned off. This system
decreases the fan's operating time, thus increasing its useful life.
