Start-up, control with I/O and ID Run
• Motor nominal current (parameter 9906 )
Allowed range: 0.2…2.0 · I
2hd
A
• Motor nominal frequency (parameter 9907 )
• Motor nominal speed (parameter 9908 )
• Motor nominal power (parameter 9909 )
Select the motor identification method (parameter 9910 ).
The default value 0 (
OFF
/
IDMAGN
) using the identification magnetization is suitable for most
applications. It is applied in this basic start-up procedure. Note however that this requires
that:
• parameter 9904 is set to 1 or 2 (
VECTOR
:
SPEED
), or
• parameter 9904 is set to 3 (
SCALAR
:
FREQ
) and parameter 2101 is set to 3 (
SCALAR FLYST
)
or 5 (
FLY
+
BOOST
).
If your selection is 0 (
OFF
/
IDMAGN
), move to the next step.
Value 1 (
ON
), which performs a separate ID Run, should be selected if:
• vector control mode is used [parameter 9904 = 1 or 2 (
VECTOR
:
SPEED
)],
• 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.
If you decide to do the ID Run [value 1 (
ON
)], continue by following the separate instructions
given on page 40 in section How to perform the ID Run and then return to step DIRECTION
OF THE MOTOR ROTATION on page 38 .
