The Allen-Bradley 1756-M02AE is an analog encoder (AE). The module has two axes and an orthogonal position feedback output. The module controls drives or actuators that require +/ -10V speed or torque reference inputs. It monitors the position feedback through the orthogonal encoder input, ensuring that the actuator (motor) follows the profile. It also generates a mock command reference for the drive.
The 1756-M02AE module can be used with multiple orthogonal output rotation and linear sensors. It can be mounted to the ControlLogix chassis, including 1756-A4, 1756-A7, 1756-A10, 1756-A13, and 1756-A17, but it requires RTB or detachable terminal blocks. The 1756-TBCH or 1756-TBS6H RTB are both compatible with this module, and they can be installed in any available slot in the chassis. Before installing the module with RTB into the chassis, ground the chassis and the power supply.
It has a position cycle update rate of 500 microseconds and a speed cycle update rate of 250 microseconds. The drive model time constant is 15 microseconds and the torque ring bandwidth is 106 Hz. The 1756-M02AE module also has an in situ limit switch input, a drive fault input, and a drive enable output. The 1756-M02AE module can be directly connected to three. The servo loop type is a nested PI digital position and speed servo. Its gain resolution is 32-bit floating point and its rate is 5 kHz. Its absolute position range is +/-1,000,000,000 encoder count.
The input type of the 1756-M02AE module is an encoder input with incremental AB orthogonal and marked. The encoder mode has 4X quadrature and a maximum encoder rate of 4 MHz counts per second.
The module has 5V or 24V position register input. Its current consumption is 700 mA (5.1V DC) and 2.5 mA (24V DC), and the module power is 3.63 W. The power consumption of the module is 5.5 W and its electrical interference is 5V differential (optical isolation). It has an on-voltage range of 3.4 to 5V and an off-state voltage range of 0 to 1.8V.
It also has an optically isolated current absorption input type. Its nominal voltage is 24V DC. The minimum on-state voltage is 17V DC, the maximum on-state voltage is 26.4V DC, and the maximum off state voltage is 8.5V DC.
Allen-Bradley 1756-M02AE is Allen-Bradley's solution for analog motion control requirements. The module can be mounted with any ControlLogix chassis and provides open or closed loop motion control. The module provides an analog output of +/-10VDC and is compatible with devices that receive +/-10VDC as a reference for speed or torque commands. The module integrates two (2) axes, however, the ControlLogix controller supports up to 32 axes, which can be achieved by installing additional modules.
The module receives an incremental AB orthogonal encoder with a label. The encoder mode is 4X orthogonal and the rate is 4MHz per second. The discrete input channels of the module are optically isolated and support current absorption configuration. The nominal input voltage is 24VDC, the minimum on-state voltage is 17VDC, and the maximum on-state voltage is 26.4VDC. The maximum off state voltage is 8.5VDC.
The servo output type of the module is analog voltage with a range of +/- 10VDC and a resolution of 16 bits. It is used as a speed and torque reference for connecting the servo drive modules. The discrete output channel of the module is the solid state isolation relay contact output. The nominal operating voltage of the output is 24VDC and the maximum operating voltage is 26.4VDC.
It can be installed in standalone or distributed applications, as the module supports all ControlLogix controllers and communication modules.
