"F" Group: Main Profile Parameters

"F" Group: Main Profile Parameters

The basic frequency (speed) profile is
defined by parameters contained in the
"F" Group as shown to the right. The set
running frequency is in Hz, but accelera-
tion and deceleration are specified in the
time duration of the ramp (from zero to
maximum frequency, or from maximum
frequency to zero). The motor direction
parameter determines whether the keypad
Run key produces a FWD or REV command. This parameter does not affect the intelli-
gent terminal [FWD] and [REV] functions, which you configure separately.
Acceleration 1 and Deceleration 1 are the standard default accel and decel values for the
main profile. Accel and decel values for an alternative profile are specified by using
parameters Ax92 through Ax93. The motor direction selection (F004) determines the
direction of rotation as commanded only from the keypad. This setting applies to any
motor profile (1st or 2nd) in use at a particular time
Func.
