Before you connect the motors to the sat-nms ACU-RMU, take care that the circuit breakers F1, F2 and if available F4 are in off position before connecting the motors.

1. Connect the motors to the sat-nms ACU-RMU as described in chapter 4.2.2 .
2. Connect the emergency stop button to J6. If you do not have one, take care that Pin A and B as well as Pin C and D are bridged. Without a connection between these pins the power supply of the motors is disabled.
3. Press the STOP button on the sat-nms ACU-RMUs website. By this you can be sure that no motor movement will occur by switching on the circuit breakers.
4. Turn on circuit breaker F1 and F2, the frequency inverters have to run now.
5. Set the motor parameters to the frequency inverters as written in chapter 3.3.2 to the desired values.
6. Check the motor rotating directions, if necessary change it by interchanging 2 phase-wires of the motor cable.
7. If available, turn on F4 now and check the rotational direction of the POL Motor. If necessary, change + and - cable at J5.1 to reverse the direction.
8. Drive the antenna in every direction (AZ, EL and if available 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!
9. 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 3.3 Frequency Inverters .
