Page 4: Introduction
1.1.3 Installation The UD51 must be fitted in the small option module bay of the Unidrive. All connections to the drive are made by a multi-way connector. Connections from external equipment are made by a plug-in 16-way screw-terminal block on the UD51. -

Some parameters have a profound effect on the operation of the drive. They must not be altered without careful consideration of the impact on the controlled system. Measures must be taken to prevent unwanted changes due to error or tampering. UD51 User Guide www.controltechniques.com Issue Number: 5... -
Page 7: Installing The Ud51
1. Before installing the UD51 in the Unidrive, ensure the AC supply has been disconnected from the drive for at least 10 minutes. 2. Check that the exterior of the UD51 is not damaged, and that the multi- way connector is free from dirt and debris. Do not install a damaged or dirty UD51 in the drive. - Page 8 Figure 3-1 Installing the UD51 in the Unidrive UD51 User Guide www.controltechniques.com Issue Number: 5...

Ensure that the supply to be used is suitable for the encoder. CAUTION The UD51 can be used with an encoder that does not produce Z marker NOTE pulses. In this case, ensure that the Z marker pulse inputs are left unconnected.

Main feedback: Quadrature encoder connected to the 15-way D-type connector in the drive The UD51 can be used to supply a speed reference signal to another drive or to a controller Signal format can be either quadrature AB or frequency and direction (F/D). -
Page 14: Encoder Shaft Position
Encoder shaft position The UD51 monitors the change in position of the encoder shaft by detecting the states of the quadrature A and B signals. Zero position is detected from the appropriate edge of the Z marker pulse, as follows:... - Page 15 Figure 5-4. UD51 User Guide Issue Number: 5 www.controltechniques.com...
