P2.2.5
b
DI3 function
ID 1805
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
4
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 t
o IO terminal this input when closed will perform the action defined by
P2.1.3;
3 = Reverse - when start/stop logic is set to 3 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 7 preset speeds are selected via 3 binary inputs, this is least significant bit in that binary input;
10 = Preset speed B1 - the 7 preset speeds are selected via 3 binary inputs;
11 = Preset speed B2 - the 7 preset speeds are selected via 3 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 parameters - 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 set point select - when open, parameter set point 1 is active: when closed, set point 2 is active;
24 = Motor interlock 1 - when closed, 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 reference 1/2 sel. - when fire mode is active and this input is open, fire mode reference 1 will be active: when closed,
fire mode reference 2 will be active;
28 = Fire mode reverse - when fire mode is active and this input is open, direction will be forward: when closed, reverse;
29 = DC brake active - when closed, DC injection braking will be active;
30 = Preheat active - when closed, preheat mode will be active; or
31 = Derag. enable - when closed, the Derag. cycle for pumps will be initiated.
Description:
Defines the function of digital input 3.
