H-22 Motor Feedback Loss Timeout
. Warning/Alarm 61
Feedback Error is related to the Motor Feedback Loss
Function.
H-21 Motor Feedback Speed Error
Range:
Function:
300 RPM
*
[1 - 600 RPM] Select the max allowed error in speed
(output speed vs. feedback).

H-22 Motor Feedback Loss Timeout
Range:
Function:
0.05 s
*
[0 - 60 s] Set the timeout value allowing the speed
error set in
H-21 Motor Feedback Speed Error
to be exceeded before enabling the function
H-24 Tracking Error Function
Option:
Function:
This function is used to monitor that the
application follows the expected speed profile.
In Closed loop the speed reference to the PID
is compared to the encoder feedback (filtered)
In open loop the speed reference to the PID is
compensated for slip and compared to the
frequency that is sent to the motor
(
DR-13 Frequency
).
The reaction will be activated if the measured
difference is more than specified in
for the time specified in
A tracking error in closed loop does not imply
that there is a problem with the feedback
signal! A tracking error can be the result of
torque limit at too big loads.

Warning/Alarm 78 Tracking Error is related to the Tracking
Error Function.
H-25 Tracking Error
Range:
Function:
10 RPM
*
[1 - 600
RPM]
Enter the maximum permissible speed
error 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.
H-26 Tracking Error Timeout
Range:
Function:
1 s
*
[0 - 60 s] Enter the time-out period during which an error
is permissible.
H-27 Tracking Error Ramping
Range:
Function:
100 RPM
*
[1 - 600
RPM]
Enter the maximum permissible speed
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.
H-28 Tracking Error Ramping Timeout
Range:
Function:
1 s
*
[0 - 60 s] Enter the time-out period during which an error
while Ramping is permissible.
H-29 Tracking Error After Ramping Timeout
Range:
Function:
5 s
*
[0 - 60 s] Enter the time-out period after ramping where
are still active.
