Table 66. HVAC parameters (Cont.).
P8.2 - Fire mode (*DM1 PRO).
P8.2.1
ab
Fire mode protection
ID 535
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Closing contact initiates fire mode function.
1 = Opening contact initiates fire mode function.
Description:
This parameter determines whether the fire mode function is determined by a contact closure or contact opening on the desired digital
input function select fire mode.
Note: When fire mode is enabled, this causes the drive to ignore any fault and run till its death. Warranty will be non-valid in the case
this is enabled and the drive causes issues to the system.
P8.2.2
ab
Fire mode reference select function
ID 536
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Fire mode minimum frequency;
1 = Fire mode reference;
2 = Fieldbus reference - reference from fieldbus process in;
3 = AI; or
4 = PI1 control - follows the PI control algorithm settings.
Description:
This parameter allows for setting the reference location for when the fire mode is enabled.
P8.2.3
b
Fire mode minimum frequency
ID 537
Minimum value:
MinFreq. Hz
Maximum value:
MaxFreq. Hz
Default value:
15.00
Description:
This parameter sets the minimum output frequency for fire mode. This can be used as a selection for reference command.
P8.2.4
b
Fire mode frequency reference 1
ID 565
Minimum value:
0.0%
Maximum value:
100.0%
Default value:
75.0%
Description:
This parameter sets the drive operating percentage based off the 0% being minimum frequency (P1.1) and 100% being maximum
frequency (P1.2) for fire mode reference 1.
P8.2.5
b
Fire mode frequency reference 2
ID 564
Minimum value:
0.0%
Maximum value:
100.0%
Default value:
100.0%
Description:
This parameter sets the drive operating percentage based off the 0% being minimum frequency (P1.1) and 100% being maximum
frequency (P1.2) for fire mode reference 2.
P8.2.6
Fire mode test enable
ID 2443
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
N.A.
Options:
0 = Disabled; or
1 = Enabled.
Description:
This parameter allows for testing the fire mode feature. With the parameter set to enable and fire mode input enabled, the drive will
run at the fire mode speed desired but all faults are enabled.
P8.2.7
ab
Smoke purge frequency
ID 554
Minimum value:
0.0%
Maximum value:
100.0%
Default value:
50.0%
Description:
Frequency setting for smoke purge. Preset speed used for a digital input selection. The percentage is based off the 0% being minimum
frequency (P1.1) and 100% being maximum frequency (P1.2).
P8.3 - Protections (*DM1 PRO).
P8.3.1
ab
Broken belt protection
ID 317
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = No action;
1 = Warning;
2 = Fault - stop mode after fault according to parameter stop mode; or
3 = Fault - stop mode after fault always by coasting.
Description:
If fault is set as the function, the drive will stop and activate the fault stage based on the parameter conditions and the monitoring
status of the motor. If the motor torque drops below the Fnom and F0 torque levels for the time limit, the protection is enabled.
Deactivating the protection by setting the parameter to 0 will reset the underload time counter to zero.
