Standard programposi features 55
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 is
highly recommended to force a save by using parameter 96.07 Parameter save
manually before powering down the control unit after any parameter changes have
been made.
If necessary, the default parameter values can be restored by parameter 96.06
Parameter restore.
Application programming
The functions of the firmware program can be extended with application
programming. (A standard drive delivery does not include an application program.)
Application programs can be built with function blocks based on the IEC 61131-3
standard using a PC tool available separately.
For more information, see Programming manual: Drive application programming
(IEC 61131-3) (3AUA0000127808 [English]).
Control interfaces
Programmable analog inputs
The control unit has two programmable analog inputs. Each of the inputs can be
independently set as a voltage (0/2…10 V or -10…10 V) or current (0/4…20 mA)
input by a jumper or switch on the control unit. Each input can be filtered, inverted
and scaled. The number of analog inputs are increased by installing FIO-11 or FAIO-
01 I/O extensions (see Programmable I/O extensions).
Settings
See parameter group 12 Standard AI (page 140).
Programmable analog outputs
The control unit has two current (0…20 mA) analog outputs. Each output is filtered,
inverted and scaled. The number of analog outputs are increased using FIO-xx I/O
extensions. See Programmable I/O extensions (page 56).
Settings
See parameter group 13 Standard AO.
Programmable digital inputs and outputs
The control unit has six digital inputs, a digital start interlock input, and two digital
input/outputs.
One digital input (DI6) doubles as a PTC thermistor input. See section Motor thermal
protection (page 83).
