92 Program featuresDrive configuration and programmingThe drive control program performs the main control functions, including speed,torque and frequency control, drive logic (start/stop), I/O, feedback, communicationand protection functions. Control program functions are configured and programmedwith parameters. Configuring via parametersParameters configure all of the standard drive operations and can be set via• the control panel, as described in chapter Control panel• the Drive composer PC tool, as described in Drive composer user’s manual(3AUA0000094606 [English]), or• the fieldbus interface, as described in chapters Fieldbus control through theembedded fieldbus interface (EFB) and Fieldbus control through a fieldbusadapter.All parameter settings are stored automatically to the permanent memory of the drive.However, if an external +24 V DC power supply is used for the drive control unit, it ishighly recommended to force a save by using parameter 96.07 Parameter savemanually before powering down the control unit after any parameter changes havebeen made.If necessary, the default parameter values can be restored by parameter 96.06Parameter restore.Drive control programSpeed controlTorque controlFrequency controlDrive logicI/O interfaceFieldbus interfaceProtectionsM
