FILTER Velocity Loop Filter Gain
Purpose Set the current command filter. FILTER is the bandwidth in hertz (Hz) of the low pass
filter on the output of the velocity regulator (the current command). Reducing the
value of FILTER will smooth the current command which reduces noise from high fre-
quency current pulsation.
Syntax FILTER = value
variable = FILTER
value The low pass filter roll off frequency in hertz (Hz). The maxi-
mum value is 300 Hz. Value can be a constant, a nonvolatile
variable Gn, a volatile variable Vn, or a system variable.
variable The variable may 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 Person-
ality Module is used. The value in the Personality Module is set in the Parameter
menu, Gains/Limits dialog

FNACTIVE Fkey active Flag System
Purpose Fkey pressed flag.
Syntax variable = FNACTIVE
variable If TRUE it indicates that an Fkey is pressed on the operator ter-
minal. Variable may be a nonvolatile flag Bn, a volatile flag Fn,
or another system flag.
Remarks The flag is ON when an Fkey is pressed and OFF otherwise. A common use for this
flag is to permit something to happen as long as the Fkey is pressed.

Example B2 = FNACTIVE
IF FNACTIVE = ON JOGF = ON ELSE JOGF = OFF
