Allen-Bradley PowerFlex 70 Reference Manual

2-114 Masks
Masks A mask is a parameter that contains one bit for each of the possible
Adapters. Each bit acts like a valve for issued commands. Closing the valve
(setting a bit's value to 0) stops the command from reaching the drive logic.
Opening the valve (setting a bit's value to 1) allows the command to pass
through the mask into the drive logic.
Example: A customer's process is normally controlled by a remote PLC,
but the drive is mounted on the machine. The customer does not want
anyone to walk up to the drive and reverse the motor because it would
damage the process. The local HIM (drive mounted Adapter 1) is
configured with an operator's panel that includes a “REV” Button. To assure
that only the PLC (connected to Adapter 2) has direction control, the
[Direction Mask] can be set as follows:
276 [Logic Mask]
Determines which adapters can control the drive. If the bit for an adapter is set to
“0,” the adapter will have no control functions except for stop.
