Options for optimizing the control loops

Various options are available for optimizing the control:

a.

Select motor from motor catalog

b.

Automatic motor identification (energized)

c.

Automatic motor calibration (non-energized)

d.

Tuning of the motor and the speed controller

Details

The option to be selected depends on the respective application. Depending on the selected option, different procedures become active and thus different parameter groups are influenced:

–

Rated motor data

–

Inverter characteristic

–

Motor equivalent circuit diagram data

–

Motor controller settings

–

Speed controller settings

The optimization can be carried out via the keypad or the engineering tools.

Option 1: Performing optimization with engineering tool

Option 2: Performing optimization with keypad

Performing optimization with engineering tool

The following flow diagram shows the optimization process with an engineering tool (e. g. »EASY Starter«):



a)	The relevant motor data must be set first. You benefit from very precise motor equivalent circuit diagram data by selecting the motor from the motor catalogue. Select motor from motor catalog
b)	Manually set the motor data in accordance with the manufacturer's information / motor data sheet when a third-party motor is connected to the inverter. Manual setting of the motor data
c)	The speed controller must be first reinitialised alone if the load adjustment in the optimized system has changed. Tuning of the motor and the speed controller
d)	If the application enables you to energise the system during the optimization procedure, carry out an automatic identification. This procedure results in the best possible parameter settings. Automatic motor identification (energized)
e)	If the application does not enable you to energise the system during the optimization procedure, carry out an automatic calibration. Automatic motor calibration (non-energized)

Performing optimization with keypad

Since there is no access with the keypad to the motor catalogue, first the motor data must be set manually with the keypad according to the manufacturer data/motor data sheet.

Manual setting of the motor data

The following flow diagram shows the optimisation process with the keypad:



a)	Manually set the motor data in accordance with the manufacturer's information / motor data sheet when a third-party motor is connected to the inverter. Manual setting of the motor data
c)	If the application enables you to energise the system during the optimization procedure, carry out an automatic identification. This procedure results in the best possible parameter settings. Automatic motor identification (energized)
d)	If the application does not enable you to energise the system during the optimization procedure, carry out an automatic calibration. Automatic motor calibration (non-energized)
