1771 Encoder Module

[Emir Ballard]

The1771-DL is electrically pretty simple, but has a wider input voltage range than most DC input modules (from 10 to 27 volts DC). You can see the simple sinking inputs in the user manual for the module:

The 1756-IB16IF should have been ideal for this application. It has fast inputs (the -DL had 1 ms filtering and the -IB16IF has 14 us) and isolated DC inputs that accept 10-30 V DC as either sinking or sourcing circuits.

The 1771-DL also had a triac zero speed switch on the bottom two terminals that was intended to be used with 120VAC motor control circuits. You definitely don't want to hook up any of the conductors that might have been involved in that to your 1756 module.

It looks like Pins 2 and 3 or 3 and 4 blew up, which would be Input 2 or Input 3. I can't say why those would be damaged by a 24V supply power inversion to the encoder. That should have been prevented by one of those big honking diodes.

The 1771-HS1 module is a servo controller module manufactured by Allen-Bradley/Rockwell Automation as part of the PLC-5 series that works with the IMC 120 Series motion controllers. This module comes with 32 KB of memory in its Allen-Bradley 1771-HM memory cartridge, an encoder module, an Allen-Bradley 1771-PS7 power supply module, and a maximum of 3 servo controller modules on the I/O chassis. The memory cartridge is connected to the controller module to provide storage for the entire controller module. The 1771-HS1 memory cartridge features a lithium battery for backup with a 3.6 Volts rating and a CMOS Random Access Memory (RAM) with a capacity of 32 KB for the MML program memory. Other notable features of this module include 4 red and green LED light indicators on the front panel along with a power connector for connecting the 1771-PS7 power supply module. The Allen-Bradley 1771-HS1 module comes with a power supply module rated at 120 Volts AC voltage at 1 Amp of current and at 220 Volts AC voltage at 2 Amps of current. It also uses the Allen-Bradley 1771-CAS connector cable to link the power supply to the power connector. Other features of this module include a 50-pin Axis E-stop I/O connector for receiving the encoder feedback signals, E-stop starting signals, E-stop status, and resolver feedback signals. Additionally, this connector provides fast I/O power. The 1771-HS1 module features a 15-pin AUX FDBK connector for receiving the auxiliary encoder feedback signals as well as an encoder. It also provides the encoder with power and it has an RS-232 connector on the front to allow for downloading and uploading the MML programs and AMP parameters.

The Allen-Bradley 1771-HS1 servo controller module is manufactured by Allen-Bradley/Rockwell Automation. It belongs to the PLC series that works with the IMC 120 motion controller. The 1771-HS1 module has a 1771-HM memory cartridge with a capacity of 32 KB as well as an encoder module and the 1771-PS7 power supply module.

The BASIC Module provides math functions, report generation and BASIC language capabilities for any Allen-Bradley processor that communicates with the 1771 I/O system using block-transfer. It provides: basic programming using the Intel BASIC-52 language., math functions consistent with the BASIC-52 definition, two independently configurable serial ports capable of connecting to various user devices, user accessible real-time clock with 5 ms resolution, user accessible "wall" clock/calendar with 1 second resolution, program generation and editing using a dumb ASCII terminal or a T3/T4 Industrial Terminal in alphanumeric mode, program storage and retrieval using the 1770-SA/SB Recorder, block-transfer communication capability from a PLC-2, PLC-3 or PLC-5 family processor, and on board program PROM burning.

Your module is a one-slot module with the following functions and features:

- 13 K bytes of battery backed RAM for user programs.

- 32 K bytes of EPROM storage for user software routines.

- One RS-423A/232C compatible serial communications port(PROGRAM port) which works with ASCII terminals providing operator program interaction, command level input printer output, etc. The program port baud rate defaults to 1200 baud. Initially you must set your terminal for 1200 baud. Use CALL 78 to change the program port baud rate. The program port is fixed at no parity, 1 start bit, 1 stop bit and 8 data bits.
