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.
