SCANport Control Configuration:
The SCANport controls are the functions that control the motor, like start,
stop, jog etc. The control can come from up to 6 SCANport devices and L
Option Inputs at the same time. The control is based on a ownership
mechanism which allows certain functions to have only one owner and other
functions to have multiple owners. Speed reference, direction and local
functions are the only one owner functions. The other functions like start,
stop, jog etc. are considered multiple owner functions. Ownership is when a
SCANport device or L option Input commands a function. As long as that
function is commanded, that device will be the owner of that function. For
Example: Device 1 is commanding a forward direction, this is a one owner
function. No other device can change the direction until Device 1 stops
commanding the forward direction. If Device 1 is commanding a start which
is a multiple owner function, other devices can also command a start. If
device 1 stops commanding a start, the drive will continue to run if another
device is still commanding a start.
NOTE: A rising edge is required for start and jog functions. If jog is
commanded and the drive has been stopped, Start and Jog functions will not
operate from any device until the Jog command is stopped. The same holds
true if a Start is commanded while the drive is stopped.
The parameters in the range from 340 to 350 indicate the owner of each
function. The owner is identified by the bit in the parameter as follows:
Bit 0 – L Option Inputs
Bit 1 – SCANport device 1
SCANport device number is
Bit 2 – SCANport device 2 determined by the SCANport
Bit 3 – SCANport device 3 connection.
Bit 4 – SCANport device 4
Bit 5 – SCANport device 5
Bit 6 – Internal Gateway
Bit 7 – Not Used
This is very useful for determining who may own a function.
Masking of the control functions allows control functions to be enabled or
disabled for all or some of the devices. The parameter bit configuration is
the same as the example detailed above with 0 indicating disable and 1
indicating enable. The masking control starts with the port enable mask
which enables or disables all of the devices control functions, then the local
control mask which allows a device to take full control of the drive, to the
individual masks like start, jog, direction, speed reference, clear faults and
reset.
Control Interface Option
The Control Interface Option Modes configure the Control Interface Option.
The different modes are explained in Chapter 2. The modes allow the user to
setup the inputs to meet the requirements of their application. The Input
Mode parameter 385 sets the mode and takes effect on a power cycle or reset.
The Input Status parameter 386 indicates the status of the input except for the
enable input which can be seen in parameter 54 bit 1. The Stop Select
parameters 387 & 388 select the way the stop input will function on the L
