Digital Brushless AC servo drive system - Ref.0707
Connectors
Power terminals
POWER INPUTS (L1, L2, L3).
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.
L+, Ri, Re.
Terminals to configure and connect the external ballast resistor.
CONTROL POWER INPUTS L1, L2, GROUND (X3).
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
. Total isolation between the
power and the control circuits.
ACTIVATION OF THE INTERNAL FAN.
The internal fan that cools the drive's
power elements starts when enabling the Drive Enable signal. The fan will stop
when the heatsink temperature is lower 70 °C since the Drive Enable signal
is turned off. This method decreases the fan's operating time, thus increasing
its useful life.
Control signals
Voltage ± 12 V, (pins 1, 2, 3 of X1).
Output of an internal power supply so
the user can easily generate a command signal. It offers a maximum current
of 20 mA limited internally.
Velocity command (pins 4, 5 and 6 of X1).
Velocity command input for the
motor. It admits a range ±10 V and offers an impedance of 22 k
Ω
.
Programmable analog input (pins 4 and 7 of X1).
Input of the analog
command used by some integrated function. It offers an impedance of 10 k
Ω
.
Programmable analog output 1 (pins 8 and 10 of X1).
Voltage range of
±10 V.
Programmable analog output 2 (pins 9 and 10 of X1).
Voltage range of
±10 V. They offer an analog value of a set of internal variables of the drive.
Programmable digital output 1 (pins 1 and 2 of X2).
Optocoupled open
collector output that reflects the output of some integrated functions.
Common, (pin 5 of X2).
Reference point for the following:
Drive Enable, (pin 4 of X2).
At 0 V DC no current can circulate through the
motor and it has no torque.
