Data sheet: RLI20-P Panasonic interface - 1

This data sheet contains an overview and specification of the Renishaw RLI20-P Panasonic interface. The RLI20-P provides an interface between a Renishaw laser encoder system (RLE and HS20) and a Panasonic controller (MINAS A5-series). It accepts differential analogue 1Vpp sine/cosine signals. The output is presented in RS485 format and as an incremental position reading. When used with a double pass plane mirror interferometer system (PMI) (fundamental period of sinusoids is nominally 158 nm), the RLI20-P interpolates the position data and scales it to be 1 nm/LSB. If used with a single pass retroreflector system (RRI) (nominal fundamental period of sinusoids is 316 nm), the scale would be 2 nm/LSB. The system architecture consists of: The RLI20-P is suitable for single or dual axis laser encoder applications, with each axis scaled for the individual laser wavelength. • 2 input channels, which take analogue quadrature from the Renishaw laser encoder system • A high speed interpolator that converts input to position readings and formats for Panasonic controllers • 2 RS485 output channels, an error line and the LED status indicator Maximum Velocity (Panasonic interface is limited to 0.4 m/s) Maximum data rate Controller position update rate Internal position data update rate Positional noise contribution (RMS) RLI20-P is intended to be mounted in an electrical control cabinet or similar environment. It is constructed with IP20 Protection. 100 mm connector/cable clearance is required from the front face of the RLI20-P. The RLI20-P connector kit is available to order. Part number: A-9926-0204. Fixing: Supplied with fixing kit: • 4 off M4 x 5 cap head screws • 4 off 4 mm plain washers • 2 off mount brackets It ensures that earthing is achieved directly through
