Cyclic Data Access - Dout Mapping
5.4 Cyclic Data
5.4.1 Overview
The control and status words allow the digital control and monitoring of the drive to be implemented using
a single data word for each function. Each bit in the control word has a particular function and provides
a method of controlling the output functions of the drive, such as run and direction. Each bit in the status
word provides feedback about the drive’s state of health and operational condition, such as drive healthy,
drive at speed, etc. The various Network Setpoints provide a method of editing the drives’ Frequency,
Speed, Toruque or PID control etc.
5.4.2 P44x = 1, SMV Control Word
The SMV Control Word consists of 16 control bits some of which are reserved.

12 Controller Inhibit Set to 1 to disable the drive and allow the motor to coast to a stop
13 Quick Stop Set to 1 to disable the drive and stop the ramp time defined in P127
14 PID Disable When using PID mode, setting this bit (14) to 1 will disable PID control. (Active only in Network Control)
15 DC Braking Set to 1 to activate DC injection braking. Refer to P174 for details.
