The Control Techniques UD51 is a second encoder feedback module for the Unidrive classic series of AC drives.The UD51 is used where the reference signal and motor feedback signals are both EAI485 quadrature format. The module allows the Unidrive to receive feedback from a second encoder or change the encoder input to a reference input and can also be used with frequency oand direction signals. Freeze input is also available.

The A, B amd Z inputs may be configured for frequency and direction or quadrature format. The position is latched on the rising edge of Z when the direction is forward and on the failing edge when the direction is reversed. Termination resistorss can be selected by a parameter and do not have series capacitors. Input filters and over voltage protection are fitted to all three inputs.
On the Control Techniques UD51 the F and D outputs, enable the user to monitor the frequency and direction of the encoder/drive signal. The F and D outputs are derived from either the main encoder inputs or the encoder inputs to this module. The resolution can be reduced by any powerof 2 and the formatof the output can be either frequency and direction or quadrant. Delay encoder (main or 2nd) input to output.
The signal can be programmed as a freeze input or a Z output by setting the appropriate parameter. If the Z output is chose the output is beffered version of the Z input of the main encoder. If used a freeze input when a positive transition is deteced the position of both the main encoder and the 2nd encoder inputs are stored. There may be a small delay in latching the position but bohth will be latched together. Output and input modes comply with EIA485.
