AB5 and AB51 Drivers User Manual  

 

Introduction 

 

Nanomotion Ltd.  

 

13

 

An additional, related model is the AB51 driver, built identically to the AB5 but 

carrying a different firmware. The AB51 is designed to have a minimal 

controlled Dead Zone, which is beneficial in Z applications or in repetitive 

Start/Stop mode of operation. The AB51 feeds less driving power into the 

motor at low commands, thus facilitating the controlled Dead Zone, mentioned 

above, while maintaining the motor at a lower operating temperature. The 

AB51 driver should be chosen in general applications, unless a perfect servo 

tracking or very low ripple constant velocity is needed, where AB5 is 

preferable. 

 

 

Main Features 

1.2

•

  High precision (11 bits) control of the output power stage. 

•

  Zero Dead Band in AB5 and minimal Dead Band in AB51. 

•

  Drives up to four HR8 motors. 

•

  Four operation modes: Velocity, Step, and Brake On/Off. 

•

  Interface to an analog command. 

•

  Modular design, to allow replacement of configuration specific Personality 

cards. 

•

  Discrete inputs enabling feedback from external sources, such as: limit 

switches, Emergency_Stop command, etc. 

•

  Three color LED indicators. 

•

  Over Current, Over Voltage, and motor interlock protections. 

•

  Minimized sensitivity to cable length. 

•

  User defined Enable input logic. 

•

  Thermal Protection mechanism
