P2.2.3
b
DI2 function
ID 1803
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
2
Options:
0 = Not used, no action.
1 = IO terminal start signal 1, when the control source is set to IO terminal, this input when closed will perform the action defined by
P2.1.3.
2 = IO terminal start signal 2, when the control source is set to IO terminal, this input when closed will perform the action defined by
P2.1.3.
3 = Reverse, when Start/Stop logic is set to three start pulse stop pulse, this input will cause the drive to start in the reverse direction.
4 = Ext. fault 1, when closed, Ext. fault 1 will be activated.
5 = Ext. fault 2, when closed, Ext. fault 2 will be activated.
6 = Ext. fault 3, when closed, Ext. fault 3 will be activated.
7 = Fault reset, when closed, all active faults will be reset.
8 = Run enable, when closed, the drive will allow a start command and be in the ready state.
9 = Preset speed B0, the seven preset speeds are selected via three binary inputs. This is least significant bit in that binary input.
10 = Preset speed B1, the seven preset speeds are selected via three binary inputs.
11 = Preset speed B2, the seven preset speeds are selected via three binary inputs. This is most significant bit in that binary input.
12 = Jog enable, when closed, the jog speed defined at P2.3.8 will override the frequency reference.
13 = Accel. pot value, when closed, the motor potentiometer value will increment at the rate defined by motor pot ramp time.
14 = Decel. pot value, when closed, the motor potentiometer value will decrement at the rate defined by motor pot ramp time.
15 = Reset pot zero, when closed, the motor potentiometer value will reset to zero.
16 = Accel./decel. time set, when open, accel./decel. time 1 will be used. When closed, accel./decel. time 2 will be used.
17 = Accel./decel. prohibit, when closed, the drive will hold the output frequency and ignore changes to the reference value.
18 = No access to param., when closed, no changes can be made to any setting in the drive.
19 = Remote control, when closed, the drive will be forced to the remote control place.
20 = Local control, when closed, the drive will be forced to the local control place.
21 = Parameter 1/2 Sel., when open, parameter set 1 is active. When closed, Parameter set 2 is active.
22 = PI controller, when closed, the drive will force the reference source to PI controller output.
23 = PI setpoint select, when open, parameter setpoint 1 is active. When closed, setpoint 2 is active.
24 = Motor interlock 1, when closed, the motor will be enabled to run.
25 = Smoke mode, when closed, smoke mode will be active.
26 = Fire mode, when closed, fire mode will be active.
27 = Fire mode Ref. 1/2 Sel., when fire mode is active and this input is open, fire mode Ref. 1 will be active. When closed, fire mode
Ref. 2 will be active.
28 = Fire mode reverse, when fire mode is active and this input is open, the direction will be forward. When closed, the direction will
be reverse.
29 = DC brake active, when closed, DC injection braking will be active.
30 = Preheat active, when closed, preheat mode will be active.
31 = Derag. enable, when closed, the Derag. cycle for pumps will be intiated.
