Description

The SNAP-IDC5Q quadrature input module is part of the SNAP

PAC System. It mounts on a SNAP PAC rack and is designed to

allow a SNAP PAC brain or R-series controller with high-speed

counting capability (either a standard wired model or a

Wired+Wireless

position information from quadrature encoder devices. The

module outputs a pulse to the SNAP PAC processor upon each

change in quadrature state. The processor counts the module

output pulses and keeps track of the direction and position.

The SNAP-IDC5Q can be used with most quadrature devices,

including transducers with TTL, CMOS, and open collector

outputs. All inputs are isolated from each other and do not

share any common connections.

SNAP racks use a retention rail locking system that holds

modules securely to the rack. Normally, a hold-down screw is

not required. However, for applications that require additional

module security, each module has provisions for two 4-40 by

½-inch standard machine screws to hold each module in

position on the SNAP rack.

Module Operation

For each axis, the SNAP-IDC5Q quadrature module converts a

quadrature signal to a stream of pulses that is sent to the I/O

processor on one of two input channels. The rotation direction

of the encoder determines which output is used.

The position count is incremented when the signal into the A

channel leads the signal into the B channel. It is decremented

when the signal into the B channel leads the signal into the A

channel.

Since the I/O processor (brain or on-the-rack controller) has a

maximum input count rate, the maximum allowable RPM at

which the encoder may turn is related to the number of cycles

per turn that the encoder outputs. See charts on the next two

pages.

Notes for legacy hardware: The SNAP-IDC5Q is also

compatible with Ethernet-based SNAP-B3000-ENET and

* The SNAP-IDC5Q supports an encoder input frequency of 25

kHz. However, legacy I/O brains have limited quadrature

counting capability. The following limits apply to them:

2.5 kHz for SNAP-B3000-ENET brains

4 kHz for SNAP-UP1-ADS brains

5 kHz for other legacy brains with high-speed counting
