Configuring the User Bit Mask Register

The User Bit Mask is a 32-bit parameter that can be configured through Power Tools Pro, in the User Program, or over the

communications network. The default value for the Mask register is 0xFFFFFFFF (HEX), or all bits ON. To change the Mask

value using PowerTools Pro, navigate to the Mask tab on the User Bits view, see Figure 66.

In the User Bits Mask view, each bit of the Mask can be set to 0 or 1 individually. ON (or 1) is indicated by a shaded square,

and OFF (or 0) is indicated by an empty square. Bit 31 is the most significant bit in the word, and bit 0 is the least significant

bit. If the bit is shaded, it means that particular bit will be passed through when written.

Each additional group of 32 User Bits that are added, a new Mask parameter will appear for that group. Mask 0 will control

the mask for User Bits 0 through 31. Mask 1 will control the mask for Bits 32 through 63. This sequence repeats for each

additional 32 bits that is added.

Figure 66: User Bits Mask View

To configure the mask in a user program, the parameter named BitRegisiter.#.ValueMask is written to. The mask can be

written to using Hexadecimal based values or decimal based values. To write a hexadecimal value to the parameter, the hex

value must be preceded with the characters "0x". To write a decimal value to the parameter, normal notation is used. For

examples of writing the Mask to a value in a program, see below.

For example: BitRegister.1.ValueMask = 0xFFFF0000

This example writes a 1 into all bits of the upper sixteen bits, and 0 into each of the lower sixteen bits using hexadecimal

value. To write the same value using decimal notation, the following instruction would be used.

For example: BitRegister.1.ValueMask = 4294901760

This instruction would also write a 1 into each of the upper sixteen bits, and a 0 into each of the lower sixteen bits.

I/O Setup Group

The I/O Setup group contains views that control input and output functions as well as other drive functions. These views are

as follows: Selector, Assignments, Input Lines, Output Lines, Analog Inputs, and Analog Outputs. These can be viewed by

expanding I/O Setup then simply clicking on any one of the setup views underneath the I/O Setup.

Assignments

External control capability is provided through the use of assignments to the Sources (Drive Inputs and Module Inputs) or the

Destinations (Drive Outputs and Module Outputs). Assignments provide a mechanism for the user to define the internal and

external dynamic control structure to separate complex motion profiles. These functions directly correspond to any input or

output line on the drive or the FM-3/4 module. External controllers, such as a PLC or other motion controllers, may be

connected to affect or monitor the device’s operation.

All inputs and outputs are configured as sourcing and are designed to operate from a +10 to 30 Vdc power source. The user

is responsible for limiting the output current to less than 200 mA for each digital output.
