Parameter Descriptions
4-37 Tracking Error Ramping
Range: Function:
100 RPM [1 - 600 Enter the maximum permissible speed
*
RPM] error between the motor speed and the
output of the ramp when ramping. In
open loop the motor speed is estimated
and in closed loop it is the feedback from
encoder/resolver.
4-38 Tracking Error Ramping Timeout
Range: Function:
1.00 s [0.00 - 60.00 s] Enter the time-out period during which
*
an error greater than the value set in
4-37 Tracking Error Ramping while
Ramping is permissible.
4-39 Tracking Error After Ramping Timeout
Range: Function:
5.00 s [0.00 - 60.00 s] Enter the time-out period after ramping
*
where 4-37 Tracking Error Ramping and
4-38 Tracking Error Ramping Timeout are
still active.
3.6.3 4-5* Adjustable Warnings
Use these parameters to adjust warning limits for current,
speed, reference and feedback. Warnings that are shown on
the display can be programmed as an output or sent via
serial bus.
Warnings are shown on display, programmed output or
serial bus.

4-50 Warning Current Low
Range: Function:
0.00 A [Application Enter the I

dependant] current falls below this limit, the display
reads Current Low. The signal outputs can
be programmed to produce a status
signal on terminal 27 or 29 (FC 302 only)
and on relay output 01 or 02 (FC 302
only). Refer to the drawing in this section.
4-51 Warning Current High
Range:
Application [Application Enter the I
dependent dependant] motor current exceeds this limit,
*
the display reads Current High. The
signal outputs can be
programmed to produce a status
signal on terminal 27 or 29 (FC 302
only) and on relay output 01 or 02
(FC 302 only). Refer to the drawing
in this section.
4-52 Warning Speed Low
Range: Function:

speed exceeds this limit, the display
reads Speed Low. The signal outputs can
be programmed to produce a status

only).
4-53 Warning Speed High
