Start-up, control with I/O and ID Run
How to perform the ID Run
The drive estimates motor characteristics automatically using identification
magnetization 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), and
• parameter 9904 = 1 (
VECTOR
:
SPEED
) or 2 (
VECTOR
:
TORQ
), or
• parameter 9904 = 3 (
SCALAR
:
FREQ
) and parameter 2101 = 3 (
SCALAR FLYST
) or
5 (
FLY
+
BOOST
).
In most applications there is no need to perform a separate ID Run [ 9910
ID RUN
=
1 (
ON
)]. The ID Run should be selected if:
• vector control mode is used [parameter 9904 = 1 (
VECTOR
:
SPEED
) or
2 (
VECTOR
:
TORQ
)], and/or
• the 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 is required.
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 Assistant Control
Panel see page
49 and for Basic Control Panel page 67 in chapter Control panels .
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.
Check that the values of the motor data parameters 9905 … 9909 are equivalent to those on
the motor nameplate, as shown in the steps on page 33 .
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
2hd
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.
