Parameter Descriptions
4-35 Tracking Error
Range: Function:
10 [1 - 600 Enter the maximum permissible speed error
RPM RPM] between the motor speed and the output
*
of the ramp when not ramping. In open
loop the motor speed is estimated and in
closed loop it is the feedback from
encoder/resolver.
4-36 Tracking Error Timeout
Range: Function:
1 s [0 - 60 s] Enter the time-out period during which an error
*
greater than the value set in
parameter 4-35 Tracking Error is permissible.
4-37 Tracking Error Ramping
Range: Function:
100 [1 - 600 Enter the maximum permissible speed
RPM 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 s [0 - 60 s] Enter the time-out period during which an error
*
greater than the value set in
parameter 4-37 Tracking Error Ramping while
Ramping is permissible.
4-39 Tracking Error After Ramping Timeout
Range: Function:
5 s [0 - 60 s] Enter the time-out period after ramping where
*
parameter 4-37 Tracking Error Ramping and
parameter 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 are shown on the LCP, and can be programmed
to be outputs or to be read out via serial bus in the
Extended Status Word.

Function:
Enter the I value. When the motor current
LOW
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 Illustration 3.32.
