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.
