Start-up, control with I/O and ID Run
54
How to perform the ID Run
The drive estimates motor characteristics automatically when the drive is started for
the first time and after any motor parameter (group
99 START-UP DATA ) is changed.
This is valid when parameter 9910 ID RUN has value 0 (OFF/IDMAGN).
In most applications there is no need to perform a separate ID Run. The ID Run
should be selected if:
• vector control mode is used [parameter 9904 = 1 (VECTOR:SPEED) or
2 (VECTOR:TORQ)], and
• operation point is near zero speed and/or
• operation at torque range above the motor nominal torque, over a wide speed
range, and without any measured speed feedback (i.e without a pulse encoder) is
needed.
Note: If motor parameters (group 99 START-UP DATA ) are changed after the ID
Run, it must be repeated.
ID Run procedure
The general parameter setting procedure is not repeated here. For Basic Control
Panel, see page
63 and for Assistant Control Panel, see page 74 in chapter Control
panels . The ID Run cannot be performed without a control panel.
PRE-CHECK
WARNING! The motor will run at up to approximately 50…80% of the nominal speed
during the ID Run. The motor will rotate in the forward direction. Ensure that it is
safe to run the motor before performing the ID Run!
De-couple the motor from the driven equipment.
If parameter values (group 01 OPERATING DATA to group 98 OPTIONS ) are changed
before the ID Run, check that the new settings meet the following conditions:
2001 MINIMUM SPEED < 0 rpm
2002 MAXIMUM SPEED > 80% of the motor rated speed
2003 MAXIMUM CURRENT > I
2N
2017 MAX TORQUE 1 > 50% or 2018 MAX TORQUE 2 > 50%, depending on which limit
is in use according to parameter 2014 MAX TORQUE SEL
Check that the Run Enable signal is on (parameter 1601 ).
Ensure that the panel is in local control (LOC shown on the left / at the top). Press key to
switch between local and remote control.
