OPERATING INSTRUCTIONS
FP-QUAD-510
4-Axis, Quadrature Input Module
These operating instructions describe the installation, features, and
characteristics of the FP-QUAD-510. For details on configuring
and accessing the FP-QUAD-510 over a network, refer to the user
manual for the particular FieldPoint network module you are using
with the FP-QUAD-510.
Features
The FP-QUAD-510 is a FieldPoint quadrature input module with
the following features:
• Four independent 32-bit position counters with

When defining a FieldPoint system that uses an FP-QUAD-510 module, you must calculate the power consumption. First refer to the specifications section in the user manual for your network module. The maximum number of terminal bases per bank multiplied by 1 watt is the total power the network module can supply. For example, an FP-1000 or FP-1001 can support nine terminal bases (9 × 1 W = 9 W). Next, refer to the specifications section in the operating instructions for the I/O modules. Use

Install Your Module Field Wiring The terminal base provides connections for each axis and for an external supply to power the FP-QUAD-510 input channels and field devices. The FP-QUAD-510 accepts two types of encoder signal inputs: single-ended (TTL) or differential line driver. Figure 2 shows the typical encoder wiring for differential signal input. Figure 3 shows the typical encoder wiring for single-ended signal inp

Basic Field Connections to Single-Ended Encoders The FP-QUAD-510 supports differential inputs for Phase A, Phase B, and Index signals. You can easily accommodate encoders with various phase relationships by swapping the signals and/or connecting them to the inverting inputs as specific applications require. The Index signal must occur when both the Phase A and Phase B signals are low, as shown in

Position Counter Operation Each position counter has a 32-bit binary counter that represents the current position of the shaft connected to the axis. Channels 0 through 3 contain the lowest 16 bits of these counters for axes 0 through 3 respectively. Channels 4 through 7 contain the uppermost 16 bits for axes 0 through 3 respectively. Primarily, the position counter channels increment or decrement in response to edges encountered at the Phase A and Phase B inputs. The following sections des

Reset on Index Capability You can configure each position counter to reset each time the index condition is met. An index-initiated reset resets both the upper and lower 16-bit registers associated with that axis. This is useful in applications in which only the position within one rotation of the encoder is important to the user. In this mode of operation, any count errors that occur are canceled when the index condition is met. Commands Channels 0 through 3 (the lowest 16 bits of the po

Note If the axis is stopped with the index condition true, then reading the status bit causes the bit to reset to 0. However, since the index condition is still true, the bit is immediately latched back to 1. If the Reset on Index attribute (see Position Counter Operation) is selected, then the index status bit does not need to be read between successive index pulses in order for the position counters to reset. The position counters respond to index pulses as programmed regardless of the

• As with any hazardous voltage wiring, make sure that all wiring and connections meet applicable electrical codes and common sense practices. Mount terminal bases in an area, position, or cabinet that prevents accidental or unauthorized access to wiring that carries hazardous voltages. • The isolation of the FP-QUAD-510 is certified as double-insulated for normal operating voltages of 250 Vrms. Do not use the FP-QUAD-510 as the only isolating barrier between human contact and working vol
