24 Start-up, ID run and use
- The nominal motor current is less than 20% of the nominal drive current.
Scalar mode is not recommended for permanent magnet motors.
4. Set the nominal motor values:
• Nominal power
• Nominal current
• Nominal voltage
• Nominal frequency
• Nominal speed
• Nominal torque (optional)
• Nominal cosphi
5. Examine the direction of the motor.
If it is necessary, set the motor direction with the Phase order setting or with the
phase order of the motor cable.
6. In the Motor control view, set the start and stop mode.
7. Set the acceleration time and the deceleration time.
8. Set the maximum and minimum speeds.
9. In the Control macros view, select the applicable macro.
For units with a fieldbus adapter connected: you can see the fieldbus in the
Control macros view. There are certain parameters that you need to change, eg.
the station ID. See chapter Fieldbus control through a fieldbus adapter.
10. Tune the drive parameters to the application. You can use the Assistant control
panel (ACS-AP-x), or the Drive Composer PC tool with the drive.
Do the identification (ID) run
Background information
The drive automatically estimates motor characteristics using Standstill ID run when
the drive is started for the first time, and after any motor parameter (group 99 Motor
data) is changed. This is valid when:
• parameter 99.13 ID run request selection is Standstill and
• parameter 99.04 Motor control mode selection is Vector.
In most applications there is no need to perform a separate ID run. Select the ID run
for demanding motor control connections. For example:
• permanent magnet motor (PMSM) is used
• drive operates near zero speed references, or
• operation at torque range above the motor nominal torque, over a wide speed
range is needed.
