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.

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.
