SECTION
A
A complete functional Decoder consists of a Cradle
(specific to the programmable controller type), a Decoder Module
(ASY-M8350-010), and a Filler Module (ASY-M8250-FIL). If fault
and/or motion outputs need to be directly wired to field devices,
an output module (such as, ASY-M8250-XOUT) must be used in
place of the filler module. Consult Autotech for specifications on
output module.
Card Location: Uses one or two slots (any location) in an I/O rack.
PLC Communication: Command-based communication using
standard program controller logic.
Power Requirements:
Backplane:
5 VDC @ 650mA
Customer (Input Power): 24 VDC ± 100mA
Environment Conditions:
Operating Temperature:
-10° to +130° F (-23° to +55° F)
Relative Humidity: 5 to 95% non-condensing
RESOLVER INTERFACE:
Position Transducer: Autotech's series RL 100, E7R, E8R, or RL101,
RL500 or equivalent resolvers.
Cable Length between Resolver and M8350: 2500 feet max,
shielded.
Resolver Cable: Overall foil shielded, twisted pair, such as
Autotech's cable (CBL-10T22-xxxx).
PROGRAMMING:
All features programmable from keypad or through backplane.
Scale Factor: Programmable from 19 to 4095 (Resolution 20-4096
counts per turn).
Offset: Programmable from 0 to scale factor value.
OUTPUTS:
RPM Format: Binary
Fault Detector: —TRUE (active) on power-up —FALSE if broken
resolver wire or internal fault is detected.
Motion Detector: —Low and high motion limits are
programmable from 0 to 1999 RPM —motion detector is TRUE
when the machine's RPM is within the programmed limits —
motion detector's status is available on the backplane.
Direction: CW (clockwise) or CCW (counterclockwise) indication.
On is CCW, Off is CW.
RESPONSE TIMES:
Tach Update Time: 15ms
Position, Tach and Output Status available to Backplane:
Every 700 µs typical
CONTROL INPUTS:
Program Enable (PE): PE must be TRUE for programming.
ELECTRICAL SPECIFICATIONS:
Optical Isolation: 2500 VAC RMS
Input Current: 3mA typical @ 24 VDC
Logic Levels: —TRUE: 21 to 27 VDC (not to exceed V+
relative to V-) —FALSE: <1 VDC
