4, 3, 2 or 1 Channel Synchro/Resolver-to-Digital Converter
|
The TPMC150 is a standard single-width 32 bit PMC module providing four (TPMC150-10R), three (TPMC150-11R), two (TPMC150-12R) or one channel (TPMC150-13R) of a Tracking Synchro/Resolver-To-Digital Converter (RDC) with a converter accuracy of 2 arcmin + 1LSB.
The TPMC150 is designed for use in high performance commercial and industrial systems. It can be used for many applications like motor control, robot axis control, process control, radar antenna position information, and CNC machine tooling.
Each of the up to four RDC channels on the TPMC150 utilizes DDC's versatile state-of-the-art Tracking Synchro/Resolver-To-Digital Converter RD-19231 with programmable resolution. Resolution programming allows selection of 10, 12, 14 or 16 bit conversion. This combines the high tracking rate of a 10 bit converter with the precision of a 16 bit converter. The RD-19231 provides incremental encoder emulation. Encoder phase signals A, B and Index I are fed to an on board 32 bit up-/down encoder counter with preload and output register. Additionally the synthesized encoder signals are available for external use via RS485/422 output drivers. The RD-19231 provides a 4V velocity output with a linearity of typically 0.25%, which can be used to replace a tachometer. A 24V isolated digital input per channel can be used as general purpose input or as reference input.
A 'Simultaneous Read' function allows latching of the actual values of the selected converters at the same time.
Signal Conditioning Adapters (TPMC150-Ay-xx) are required for each channel to adapt the signal levels of the Synchro/Resolver to the RD-19231 and to configure the optional reference oscillator input/output. The Signal Conditioning Adapters will be built individually to customer specification of the Synchro or Resolver specifications, and are factory installed on the TPMC150.
Four types of Signal Conditioning Adapters are available to adapt the signal levels of the Synchro/Resolver to the RD-19231: The TPMC150-A1-xxR and the TPMC150-A2-xxR use high precision, low TK discrete resistors. These Adapters are mainly used for resolver applications. The TPMC150-A3-xx and the TPMC150-A4-xx use a high precision resistor network with matched resistors. These Adapters are mainly used for synchro applications or resolver applications which require highest accuracy. Additionally the TPMC150-A2-xx and the TPMC150-A4-xx offer an on board reference oscillator with factory selectable frequencies in the range of 2 kHz to 10 kHz.
The on board encoder counter for each channel is a 32 bit up-/down counter with preload and output register. The encoder counter is fed with the emulated A, B and Index signals from the RD-19231. The counters are programmable for single, double and quad analysis of the incremental encoder signals. The counter can be manually or automatically loaded with the value of the preload register, depending on mode. An Auto Rreference Mode provides the possibility of automatic preload of the encoder counter during normal operation, whenever the motion system passes the reference position. A 'Simultaneous Read' function allows latching of the actual values of the selected encoder counters. These values can then be read successively without interfering with normal counter function.
The TPMC150 offers one digital 24V input per channel which is galvanically isolated by optocouplers. A high performance input circuit ensures a defined switching point and polarization protection against confusing the pole. The inputs are electronically debounced. Each of the four digital 24V inputs can generate an interrupt, triggered on rising or falling edge. Depending on the selected mode the input can be used as general purpose input or as reference input.
