4.3.4 Motors
Before you connect the motors to the
sat-nms ACU-ODU, take care that the circuit
breakers for the frequency inverters, motor drivers or conductors are in
off position before connecting the motors.
- Connect the motors to the sat-nms ACU-ODU
as described in chapter 4.2.3 .
- Connect the emergency stop button to its terminals, see chapter 4.2.2 . If you do not have one, take care that these
terminals are bridged. Without a connection between these pins the power
supply of the motors is disabled.
- Press the STOP button on the
sat-nms ACU-ODMs website. By this you can be
shure that no motor movement will occur by switching on the circuit
breakers.
- Turn on circuit breakers of the frequency inverters, they have to
run now.
- Set the motor parameters to the frequency inverters as written in
chapter 3.1.1 or 3.1.2 to the
desired values.
- Check the motor rotating directions, if necessary change it by
interchanging 2 phase-wires of the motor cable.
- If available, turn on POL motor circuit breaker now and check the
rotational direction of the POL Motor. If necessary, change pin 1 and 2
at POL motor terminals to reverse the direction.
- Drive the antenna in every direction (AZ, EL and POL) until the
limit switches stop the motor movement to ensure that the limit switches
work well. ATTENTION! While doing this test it is
absolutely necessary to be very mindful to check, if nothing
collides!
- Set the soft-limits to the desired values (e.g. 1° before the
hardware limit switch is activated) If you need more detailed
informations about the frequency inverters (parameter settings, fault
states etc.), please refer to chapter 3.1 Frequency
Inverters .
