Chapter 1 Detail Drive Configuration and Operation
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 value to
0) stops the command from reaching the DriveLogix. Opening the valve (setting
a bit value to 1) allows the command to pass through the mask into the
DriveLogix.
Table 3 - Mask Parameters and Functions
The individual bits for each parameter are as follows:
• Bit 0 - “Digital Input”
• Bit 1 - “Adapter 1”
• Bit 2 - “Adapter 2”
• Bit 3 - “Adapter 3”
• Bit 4 - Not Used
• Bit 5 - “Adapter 5”
• Bit 6 - Not Used
• Bit 7 - “DriveLogix”
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 5)
has direction control, the [Direction Mask] can be set as follows:
This “masks out” the reverse function from all adapters except Adapter 5, making
the local HIM (Adapter 1) REV button inoperable. See Owners on page
77 or
the PowerFlex 700S User Manual for more information.
Motor Control Mode See Autotune on page 17 .
Parameter Function
[Logic Mask] Determines which adapters can control the drive. When the bit for an adapter is set to “0,”
the adapter will have no control functions except for stop.
[Start Mask] Controls which adapters can issue start commands.
[Jog Mask] Controls which adapters can issue jog commands.
[Direction Mask] Controls which adapters can issue forward/reverse direction commands.
[Fault Clr Mask] Controls which adapters can clear a fault.
