Product Description:

The PC844-XYZ-F servo drive from Pacific Scientific has a robust construction. This drive incorporates SERCO816 ASIC functionality. The product features an all-digital DSP control. This device features minimal installation and setup time. The unit uses a noise-immune fiber optic cable for connection and supports a ring network topology. It comes with factory-assigned hardware customization. This drive allows SERCOS network communication up to a maximum baud rate of 16 MBaud.

The product complies with IEC/EN 61491 specifications. This device's setup and configuration is possible using an IBM-compatible PC. The unit has multiple inputs and outputs with optical isolation. Its parameters can be altered during the tuning process. This drive is typically used in robotics, material handling applications, and packaging machinery. The product has rugged PLC-like analog and digital inputs/outputs for maximum application flexibility. This device also features an encoder quadrature input for step or direction. The unit's IGBT power stage produces less audible noise and has high efficiency. It operates with the manufacturer's brushless servomotors.

This drive has one relay output with a rating of 30 VDC at 1 A. The product's connections are established through the front control panel. The device comes fitted with a D-Sub connector for feedback and a terminal block adapter to speed up its connections. The unit allows integration with controls or systems with SERCOS support. Its resolver feedback withstands rough environmental conditions. This servo drive is capable of delivering digital PWM sinewave high-frequency inaudible current control to ensure effective and reliable operation all the time.
