Product Description:
The SC904AN-047-01 Servo Drive is manufactured by Pacific Scientific. This servo drive supports multiple command sources including analog, incremental digital and serial interfaces. This drive offers reliable torque, velocity and position control for various industrial automation systems.
The SC904AN-047-01 servo drive operates within a voltage range of 180 – 264 V AC and supports three phase power input. It requires a transformer rated between 3 to 6 kVA and can handle a maximum AC line power of 250 kVA. This drive features an inrush peak current of 340 A (0-p) with a 2 msec pulse width that ensures safe startup operation. A 30 A, 250 V Slo-Blo fuse (Littelfuse FLM 30) is recommended for proper circuit protection. The maximum differential range is ± 13.5 V while the single ended range extends up to ± 21 V. It maintains a full scale tolerance of ± 5 % (worst case) and ± 1 % (typical) with 0.1 % full scale linearity. The signal to noise ratio varies depending on bandwidth, reaching 14 bit resolution at full A/D bandwidth, 16 bit at 150 Hz and 18 bit at 10 Hz. Offset voltage is adjustable to 0 mV and CMRR exceeds 30 dB at 60 Hz.
The SC904AN-047-01 servo drive supports quadrature encoders, step & direction, or up/down counting. The maximum input frequency for fast decoding is 800 kHz with a minimum pulse width of 0.6 μSec. It includes 16 different emulated quadrature encoder output resolutions up to 16,384 PPR. This drive features an internally limited inrush current that eliminates the need for external isolation transformers. These features make it a reliable and efficient motor control solution for industrial applications.
