R
Control circuit and main
circuit power supply
(switched in via the isolation
transformer)
R, S and T can be connected to a signal-phase or three-phase 220V
50HZ power supply. The control power supply for the driver and
the power supply for the main circuit are designed in an integrated
manner.
Note that It should not be connected to U, V and W.
S
T
PE
Power supply ground wire
Connected to the equipment housing and the power supply earth
of the workshop.
B1
External
connection
to
braking resistors
Normally not used, because the driver has a built-in resistor.
Externally connected braking resistors are used in case of a load
with large inertia.
B2
U
Output to the servo motor
U, V and W on the servo terminals must correspond to the ones on
the servo motor without misplacement. In case of incorrect
connection, the motor will pulsate, the servo will alarm, and the
servo and motor could be damaged.
Note that it should not connected with R, S and T.
V
W
PE
Motor ground wire
Connected to the PE for the housing of the servo motor.
