Chapter 2 - Commissioning
The
Enable cogging torque compensation
function allows the commissioning of the motor cogging torque
compensation. This function is saved in the amplifier EEPROM.
The
Save cogging torque data into a file
function allows to store in a PC the cogging torque value
corresponding to a motor after the acquisition procedure
(*.COG
file).
The
Write cogging torque data into the drive
function allows to upload in the amplifier the cogging torque value
corresponding to a motor, if this value has previously been stored in the PC
(*.COG
file).
Note 1:
The motor cogging torque value is checked at the amplifier power up. If it contains some errors (storage problems
in the amplifier memory), the EEPROM error is displayed and the
Enable cogging torque compensation
function is disabled.
Note 2:
When exchanging an amplifier on an axis, the file of the adjustment parameters (*.
PAR
) as well as the cogging
torque file (*.
COG
) corresponding to the motor must be uploaded once again in the amplifier.
Note 3:
When exchanging the motor or when disassembling the resolver sensor, the acquisition procedure must be
renewed.
For a brushless motor equipped with an incremental encoder, the Cogging torque
compensation is only available if the encoder is providing one marker pulse per
motor revolution.
