Drive Data Registers Overview 5 1 1 General The drive is monitored and controlled over the network by reading and writing network commands Explicit Poll or Bit Strobed to the drive s data registers The data registers are addressed over the network by a register number Reg and contain 16 bit values The data registers are divided into separate types according to function Generally speaking the Tune Config registers hold an image of the P xxx and U xxx parameters accessable by the drive s keypad and the Control Reference registers hold an image of the drives physical inputs start stop speed ref etc When the drive is configured for network control and other certain conditions are met the drive registers accessed by the network option card are selected as an alternate source for controlling the drive as opposed to the keypad and or physical input Network data written to the drive s data registers is buffered before it is transferred to the drive s internal regulator In order to minimize regulator board CPU loading the rate of transfer of register data to the drive regulator varies for different data register types Additionally some register data transfer are blocked until additional conditions are met The sections that follow describe each data type for input and output register data along with the drive s response and conditions for acceptance of transfer The presented response times do not include DeviceNet transfer times The

Poll connection provides the primary means of monitoring and controlling the drive During normal operation the DeviceNet master will transfer a group of OUTPUT data in a Poll Request If the number of data registers bytes received matches the number expected by the network option card it will accept the OUTPUT data and reply with a Poll Response containing a group of INPUT data The number and specific data registers passed in a group is fixed however during drive configuration one of two sets of groups may be selected for operation P 063 These two sets of groups are refered to as control only and control config and are defined below Some applications will make use of a large number of drives with limited functionality connected to a single network Only certain parameters and diagnostic information commonly used will be required for network control Complete configuration over the network will not be a requirement for these lowest cost highest density highest network performance applications This type of Poll connection will be referred to as the control only Poll connection The network master will issue a Poll request that contains 3 words of data for output to the drive and the drive will return a series of Poll response messages that contain 9 words of input data from the drive Other applications will accept a slower lower density network in exchange for greater drive data access over the network This type of Poll connection is refer
