P2.1.10 Identification ID631
Identification Run is a part of tuning the motor and the drive specific parameters. It is a
tool for commissioning and service of the drive with the aim to find as good parameter
values as possible for most drives. The automatic motor identification calculates or
measures the motor parameters that are needed for optimum motor and speed control.
NOTE: Set motor control mode to Frequency Control before identification!
NOTE: During identification drive will not open mechanical brake for safety reasons. If
motor rotation requires that brake is opened this needs to be achieved externally.
NOTE: During identification run torque and power limits should be above 100 %. Also
current limit should be above motor nominal current.
NOTE: During identification run acceleration time should be below 20 second.
NOTE:
identification run again.
NOTE: Small motor with long motor cabled may require reduction of switching
frequency if identification is not successful.
0 = No action
No identification requested.
1 = - Identification without rotating the motor
Current is applied to the motor but shaft will not be rotated. U/f settings are identified.
This identification is minimum requirement if motor is only to be used in open loop
control. it is however recommended to make always identification with rotating motor if
need for closed loop control comes after mechanics are connected to shaft.
