Description of parameters

The digital inputs can be used to bypass parameter P3.1 Control Place, for example, in an
emergency situation when PLC is not able to send command to the drive.

Contact closed: force the control place to I/O terminal.
P2.4.2.24 Control from Keypad
Contact closed: force the control place to keypad.
P2.4.2.25 Control from Fieldbus
Contact closed: force the control place to fieldbus.
NOTE! When the control place is forced to change, the values of Start/Stop, Direction and Reference
that are valid in the control place in question are used. The value of parameter ID125 (Keypad
Control Place) does not change. When the input opens, the control place is selected according to
keypad control parameter P3.1 Control Place.
P2.4.2.26 Enable CB Close ID1619
This input enables CB closing when the DC voltage is at a required level. It can be used
on a battery system where drive DC is charged but it is not necessary for CB to close at
this point. When the input goes high and DC is at required level, CB will close
immediately.
