Table 14. Protections (Cont.).
P6.2.4
ab
4 mA fault frequency
ID 331
Minimum value:
0.00 Hz
Maximum value:
MaxFreq Hz
Default value:
0.00
Description:
When 4 mA fault happens, the output frequency of drive goes to this preset speed when P6.2.3 = 3.
P6.2.5
ab
External fault
ID 307
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
2
Options:
0 = No action;
1 = Warning;
2 = Fault, stop mode after fault according to parameter stop mode.
3 = Fault, stop mode after fault always by coasting.
Description:
A warning or a fault action and message is generated from the external fault signal in the programmable (digital inputs function select
external fault). The status information can also be programmed into digital output relay outputs RO1 and RO2.
P6.2.11
b
STO fault response
ID 2427
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
2
Options:
0 = No Action - drive will stop, no indication shown, no reset required, have to cycle start command.
1 = Warning - drive indicate warning/if STO clears drive will run without reset.
2 = Fault - drive will indicate fault/require reset to start again.
Description:
STO fault response defines the function of how the STO input will be seen on the keypad and how the drive functions to it.
P6.2.12
a
PI feedback AI loss response
ID 2401
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = No action;
1 = Warning;
2 = Fault; or
3 = Warning: preset frequency (P6.2.13).
Description:
This parameter defines the function of the PI feedback analog input loss response. If the AI feedback is lost based off the programed AI
feedback.
P6.2.13
ab
PI feedback AI loss pre-frequency
ID 2402
Minimum value:
0.00 Hz
Maximum value:
400.00 Hz
Default value:
0.00 Hz
Description:
This parameter defines the frequency the master would run to if a feedback is lost and P6.2.12 was set to option 3.
P6.2.14
b
PI feedback AI loss pipe fill
ID 2403
Minimum value:
0.00 varies
Maximum value:
1000.00 varies
Default value:
0.00 varies
Description:
Detects loss of prime in the pump based off the measured level. If the value drops below this level for the time in P6.2.15 and below,
the frequency in P6.2.13 “loss of prime” occurs.
P6.2.15
b
PI feedback AI loss pre-frequency timeout
ID 2404
Minimum value:
0.0 s
Maximum value:
6,000.0 s
Default value:
0.0 s
Description:
PI feedback AI loss pre-frequency timeout - when P6.2.12 is set to 3 or 4, when the feedback signal is lost, the drive will run at the
frequency in P6.2.15 for the time set here. After this time, the drive will fault out on ”feedback loss”. The time is disabled when set to
0 seconds.
P6.3 - Communications.
P6.3.1
ab
Fieldbus fault response
ID 334
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
2
Options:
0 = No action;
1 = Warning;
2 = Fault; or
3 = Fault, coast.
Description:
This sets the response mode for the fieldbus fault when a fieldbus mode is used and communication is lost between the PLC and
communication port.
Each protocol has another parameter to select in all control or only in fieldbus control to set fault or warning.
