Product Description:
The SCE906NN-050-01 Servo Drive is designed for high performance motor control applications. It supports a wide input voltage range and delivers fast response and high precision. Its digital control architecture ensures stability, speed and accuracy for motion systems.
The SCE906NN-050-01 servo drive operates on an input range of 90 – 264 VAC, 47 – 63 Hz single phase. It features ride through capabilities during AC line drops—1 cycle at 90 VAC 50 Hz, 2.5 cycles at 120 VAC 60 Hz and 10 cycles at 240 VAC 60 Hz. For three phase input configurations, nominal bus voltages are 650 VDC at 480 VAC, 540 VDC at 400 VAC and 320 VDC at 240 VAC. The analog command input of the drive supports a ± 13.5 V differential range and a ± 21 V single ended range. The full scale tolerance is ± 5 % worst case and ± 1 % typical. The linearity is within 0.1 % of full scale. It supports monotonic resolution. The signal to noise ratio is optimized through high resolution A/D conversion—14 bit at full bandwidth, 16 bit at 150 Hz and 18 bit at 10 Hz. The analog offset is adjustable to zero for precise calibration. This model can be installed at a maximum elevation height of 1500 meters above sea level.
The velocity loop of the Pacific Scientific SCE906NN-050-01 servo drive has a maximum stable bandwidth exceeding 400 Hz in motion control. It updates every 250 microseconds that supports a speed command range from 0 to 21,000 rpm. The command resolution is below 0.001 rpm. This ensures highly accurate velocity control. The drive is designed for reliable high speed and high precision servo applications in automation and industrial systems.
