The old control system used GBV 5410 amplifiers and KSY 548.30-1 motors (0.51 Nm/A) to drive the antenna via an analog output signal in the range of ±5000 DAC units from the digital control loop. The DAC signal yields a voltage ±10V at 16bit resolution (i.e. 10V/32768). The amplifier produces 6A per 5V.
