[Product Description]:

The Allen-Bradley 1756-M02AS is a synchronous serial interface, or SSI, servo module. It is an analog servo interface module that has 2 axes available. Up to 32 axes of the 1756-M02AS module can be installed in a controller. This module has been optimized for control of drives or actuators that require +/-10V velocity or torque reference input. The 1756-M02AS module has an SSI position feedback output and is a cost-effective option for open-loop or closed-loop motion control of devices that support an analog motion interface. This module is compatible with a wide range of quadrature output rotary and linear transducers. SSI devices available are rotary absolute and incremental encoders, linear absolute and incremental encoders, linear laser distance, linear absolute glass scales, and linear magnetostrictive. You can use either the cage clamp 1756-TBCH or spring clamp 1756-TBS6H RTB for this module. It has two types of servo loops: torque and velocity/hydraulic. The torque has a PID with velocity feedforward position loop and its velocity loop is PI with Accel feedforward (nested) and with directional scaling and friction compensation. The velocity has a position loop of PID with velocity feedforward and accel feedforward with directional scaling and friction compensation. The velocity loop is not applicable, as it is handled by the drive or valve. The 1756-M02AS module has a gain resolution of 32-bit floating point and an absolute position range of 4,294,967,296 transducer counts. It has a selectable rate of 500Hz, 666.7Hz, 1kHz, 2kHz, and 4kHz and an update period of 250µsec, 500µsec, 1msec, 1.5msec, and 2msec. Its resolution ranges from 8 to 31 bits and it has an isolated 5V differential electrical interface (RS-422 signal). It also has an input impedance of 215 ohm differential and an output load of 100 ohm minimum. It has a clock frequency of 205kHz or 625kHz and the transducer can either be binary or gray code. It is an optically isolated, current sinking module. The 1756-M02AS module has a nominal input voltage of 24V DC, an off-state maximum voltage of 8.5V DC, and an on-state voltage that ranges from 17V DC to 26.4V DC. It has a current draw of 700 mA and 2.5 mA at 5.1V DC and 24V DC respectively. It also has a power dissipation of 5.5 W, a thermal dissipation of 18.77 BTU/hr, and an isolation voltage of 30V that is continuous from user to system.
