Chapter 1 Drive Configuration
Auto/Manual Masks
The port configuration of the Auto/Manual feature is performed through a set of
masks. Together, these masks set which ports can control the speed and/or logic
control of the drive as well as which ports can request Manual control. The masks
are configured by setting a 1 or 0 in the bit number that corresponds to the port
(Bit 1 for port 1, Bit 2 for port 2, and so forth). Digital Inputs are always
configured through Bit 0, regardless of what port the module physically resides
in. If both [Manual Ref Mask] and [Manual Cmd Mask] for a particular port are
set to 0, that port is unable to request manual control.
P324 [Logic Mask]
Logic Mask enables and disables the ports from issuing logic commands (such as
start and direction) in any mode. Stop commands from any port are not masked
and still stop the drive.
P325 [Auto Mask]
Auto Mask enables and disables the ports from issuing logic commands (such as
start and direction) while in Auto mode. Stop commands from any port are not
masked and still stop the drive.
P326 [Manual Cmd Mask]
Manual Command Mask enables and disables the ports from exclusively
controlling logic commands (such as start and direction) while in Manual mode.
If a port assumes Manual control, and the corresponding bit for the port in the
[Manual Cmd Mask] is set, no other port is able to issue logic commands. Stop
commands from any port are not masked and still stops the drive.
P327 [Manual Ref Mask]
Manual Reference Mask enables and disables the ports from controlling the
speed reference while in Manual mode. If a port assumes manual control, and the
corresponding bit for the port in the [Manual Ref Mask] is set, the drive is
commanded to the speed reference from that port. An alternate speed reference
can be commanded using P328 [Alt Man Ref Sel]. If the respective bit for the
manual control port is not set, then the drive follows its normal automatic speed
reference, even in Manual mode.
Alternate Manual Reference Select
By default, the speed reference used in Manual mode comes from the port that
requested manual control (For example, if a HIM in port 1 requests manual
control, the speed reference in Manual mode comes from port 1). If instead it is
desired to use an a different speed reference, P328 [Alt Man Ref Sel], can be used.
The port selected in the parameter is used for manual reference regardless of
which port requested manual control, as long as the port in manual control is
allowed to set the manual reference per P327 [Manual Ref Mask]. If P328 [Alt
Man Ref Sel] is an analog input, the maximum and minimum speeds can be
configured through P329 [Alt Man Ref AnHi] and P330 [Alt Man Ref AnLo].
