WORDS

SLEWEN ON/OFF

Slew Enable Motion

Purpose Enable or disable the slew rate limit for the output of the gear calculation.

Syntax SLEWEN = value

value The value may be a nonvolatile flag Bn, a volatile flag Fn, ON,

OFF or another system flag. If value is equal to ON, enable the

slew rate limit. If value is equal to OFF, disable the slew rate

limit.

Remarks When the slew rate limit is enabled, if the rate of change of the gear output exceeds the

limit, the command generated by the ULTRA Plus or IQ will be limited to the Slew

variable. This will result in the ULTRA Plus or IQ not tracking the master input

exactly because the follower system will not respond as quickly as the master when

changing velocity.

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 Person-

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

menu, Velocity/Accel dialog box.
