Drive Configuration Chapter 1
To use the H-O-A switch, the run relay and allow for network or HIM control,
the circuit can be wired as in the figure below.
Here, the stop input is high when the H-O-A switch is in the Hand or Auto
position. This eliminates the asserted stop caused when the stop input is low,
allowing for the drive to be started from several sources when the H-O-A switch
is in the Auto position.
Masks A mask is a parameter that contains one bit for each of the possible ports for the
respective PowerFlex 750-Series drive. Each bit acts like a valve for issued
commands. Closing the valve (setting a bit value to 0) stops the command from
reaching the drive. Opening the valve (setting a bit value to 1) lets the command
pass through the mask into the drive.

Parameter No. Parameter Name Description
222 Dig In Filt Mask (1) Digital Input Filter Mask. Filters the selected digital input.
324 Logic Mask Enables/disables ports to control the logic command (such as start
and direction). Does not mask Stop commands.
325 Auto Mask Enables/disables ports to control the logic command (such as start
and direction), while in Auto mode. Does not mask Stop
commands.
326 Manual Cmd Mask Enables/disables ports to control the logic command (such as start
and direction), while in Manual mode. Does not mask Stop
commands.
327 Manual Ref Mask Enables/disables ports to control the speed reference while in
Manual mode. When a port is commanding Manual mode, the
reference is forced to the commanding port if the respective bit in
this parameter is set. If an alternate speed reference source is
desired, use P328 [Alt Man Ref Sel] to select the source.
885 Port Mask Act
(2)
Active status for port communication. Bit 15 “Security”
determines if network security is controlling the logic mask
instead of this parameter.
886 Logic Mask Act (2)
Active status of the logic mask for ports. Bit 15 “Security”
determines if network security is controlling the logic mask
instead of this parameter.
