Parameter Descriptions
4-62 Bypass Speed To [RPM]
Array [4]
Range: Function:
upper limits of the speeds to be
avoided.
4-63 Bypass Speed To [Hz]
Array [4]
Range: Function:
0 Hz [0.0 - par. Some systems call for avoiding certain
*
4-14 Hz] output speeds due to resonance
problems in the system. Enter the upper
limits of the speeds to be avoided.
3.5.6 4-7* Position Monitor
4-70 Position Error Function
Option: Function:
NOTICE
This parameter is only available with
software version 48.XX.
Select the function which is activated when the
position error exceeds the maximum allowed
value. Position error is the difference between the
actual position and the commanded position. The
position error is the input for the position PI
controller.
[0] Disabled The frequency converter does not monitor the
*
position error.
[1] Warning The frequency converter issues a warning when
the maximum allowed position error is exceeded.
The frequency converter continues operation.
[2] Trip The frequency converter trips when the
maximum allowed position error is exceeded.

Function:
NOTICE
This parameter is only
available with software
version 48.XX.
Enter the maximum allowed
position tracking error in
position units defined in
parameter group 17-7* Position
Scaling. If this value is exceeded
during the time set in
parameter 4-72 Position Error
Timeout the position error
function in
parameter 4-70 Position Error
Function is activated.

4-72 Position Error Timeout
Range: Function:
NOTICE
0.100 [0.000 -
s 60.000 s]
*
This parameter is only available with
software version 48.XX.
If the error defined in
parameter 4-71 Maximum Position Error is
present longer than the time in this
parameter, the frequency converter activates
the function selected in
parameter 4-70 Position Error Function.
4-73 Position Limit Function
Option: Function:
NOTICE
This parameter is only available with
software version 48.XX.
Select the function which is activated when the
position is outside the limits defined in
parameter 3-06 Minimum Position and
parameter 3-07 Maximum Position.
[0] Disabled The frequency converter does not monitor the
position limits.
[1] Warning The frequency converter issues a warning when
the position is outside the limits.
[2] Warning & The frequency converter issues a warning when
Trip the set target is outside the position limits. The
frequency converter starts the positioning and
then trips when the position limit is reached.
[3] Abs. Pos. The frequency converter monitors position limits
Mode only in absolute positioning mode. The
*
Stop frequency converter issues a warning and stops
at the position limit when the target position is
outside the position limits.
[4] Abs. Pos. The frequency converter monitors position limits
Md. Stop only in absolute positioning mode. The
& Trip frequency converter stops at the position limit
and trips when the target position is outside the
position limits.
[5] Position When the set target is outside the position
Stop limits, the frequency converter uses the position
limit as target. This option works in all modes of
operation including speed and torque control.
The frequency converter issues a warning when
at limit position.
[6] Position When the set target is outside the position
Stop & limits, the frequency converter uses the position
Trip limit as target. This option works in all modes of
operation including speed and torque control.
The frequency converter trips when at limit
position.
