C-50

This bit affects what happens when the module loses contact with the Programmable Controller.

When this bit is set, the module will finish any move it has started, otherwise it will halt

immediately upon detecting loss of contact with the PLC. This is useful for finishing a move that

must complete to prevent machine downtime (for example, a partial shot in an injection-molding

machine).

Bit 3 - Simulate bit

When this bit is set, the drive output is set to zero and the magnetostrictive transducer inputs are

ignored. Internally the Target Position is used as the Actual Position. This mode is used for

debugging. (The transducer error bits and LEDS will be cleared.)

Note: Drive output is always 0 volts while in simulate mode; no commands, including open loop,

will change this.

Bits 1 - 2 - Prescale Divisor Bits

Prescaling may be desired on systems with long strokes. The prescale bits are used along with

the Scale parameter to convert Transducer Counts to Actual Position. The effect is to divide the

Scale by 1, 2, 4, or 8. The divide-by factor is specified as follows:

Counts

Bit

The advantage of these bits is that they let you maintain a higher resolution in the Scale

parameter. For example, a Scale of 31027 and a divide-by of 4 gives an effective scale of

7756.75. Without using the divide-by bits, the Scale would have to be rounded up to 7757, which

has less resolution—with a 64" rod, the rounded value would make a 0.002" error at 64". Note:

The stroke is always limited to 220 inches due to the 18-bit transducer counter resolution.

These bits must be zero for Resolver modules.

Bit 0 - Integrator Limit

When this bit is cleared, the integrator limit is 20% of full drive. When the bit is set, the limit is

80%. If the integrator tries to go above the limit, the Integrator Windup bit in the status word is set

and the integrator value is held at the limit. The integrator limit is designed to prevent the drive

output from saturating.

Note: The actual drive output may be reduced based on the values of the Extend Feed Forward

and Retract Feed Forward .

C.4.2 Configuration Word Bit Map

The axis Configuration word contains 16 bits of information. The hexadecimal table below

provides an easy way to convert hexadecimal numbers to bit patterns.
