WORDS

IXnPm

Position, Latched Interrupts

Purpose Position of encoder m latched by encoder n index interrupt.

Syntax variable = IXnPm

n The number of the encoder source of the index interrupt: n =1

or 2.

m The number of the encoder from which position is read: m = 1

or 2.

variable The variable may be a nonvolatile variable Gn, a volatile vari-

able Vn, or a system variable.

Remarks When an encoder 1 index interrupt occurs, the position of encoder 1 is captured and

stored in the variable IX1P1.

See Also IDXn, FIDXn

Example

V1 = IX1P1

V2 = IX2P2

G7 = IX1P2 - IX2P1

IZONE

Integrator Zone, Position Loop Gain

Purpose Set the region around the commanded position for which the position regulator inte-

grator is active. If IZONE is set to zero or KI = 0, the integrator is not active.

Syntax IZONE = distance

variable = IZONE

distance Specifies a distance around the commanded position in user

units. User units are defined by the SCALE parameter. The

value can be a constant, a nonvolatile variable Gn, a volatile

variable Vn, or a system variable.

variable The variable can be a nonvolatile variable Gn, a volatile vari-

able Vn, or a system variable.

Remarks Changes made to this variable by a program are only in effect while the program is

running. When the program ends it will return to the value stored in the Personality

Module. If no change is made to this variable by the program, the value in the Per-

sonality Module is used. The value in the Personality Module is set in the Parameter

menu, Gains/Limits dialog box.
