Description
This command can be used to start the automatic determination of the resolver parameter RK (sine/cosine gain factor). To do this, the output stage must be enabled and the drive must be able to move freely. While this command is being carried out, the motor makes approx. 2.5 turns at the given velocity. If CALCRK is started without parameter, the default value is used. After this function has been completed, the newly determined RK parameter can be stored in the EEPROM, using the SAVE command. This command can be used to reduce the current ripple of the motor at high velocity. It can only be used with resolver feedback. Therefore the value of RK is: 12.000 = RK = 19.000 A value of 16384 is the amplification of 1.0 example: RK=18000 -> amplification of 1.098 RK=16000 -> amplification of 0.976 |
