Chapter 1 Drive Configuration
Owners An owner is a parameter that contains one bit for each of the possible port
adapters. The bits are set high (value of 1) when its adapter is currently issuing
that command, and set low (Value of 0) when its adapter is not issuing that
command.
Parameters and Functions
• P919 [Stop Owner] indicates which port is issuing a valid stop command.
• P920 [Start Owner] indicates which port is issuing a valid start command.
• P921 [ Jog Owner] indicates which port is issuing a valid jog command.
• P922 [Dir Owner] indicates which port has exclusive control of direction
command.
• P923 [Clear Flt Owner] indicates which port is currently clearing a fault.
• P924 [Manual Owner] indicates which port has requested manual control
of all drive logic and reference functions.
• P925 [Ref Select Owner] indicates which port is issuing a valid reference
select.
The bits for each parameter can be broken down as follows.
Ownership falls into two categories.
Exclusive : Only one adapter at a time can issue the command and only one bit in
the parameter is high.
Non Exclusive : Multiple adapters can simultaneously issue the same command
and multiple bits can be high.
Some ownership must be exclusive; that is, only one adapter at a time can issue
certain commands and claim ownership of that function. For example, it is not
allowable to have one adapter command the drive to run in the forward direction
while another adapter is issuing a command to make the drive run in reverse.
Direction control ownership is exclusive.
Conversely, any number of adapters can simultaneously issue stop commands.
Stop control ownership is not exclusive.
