P6.2.7
ab
Unit under temperature protection
ID 1564
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 protection sets the response to a low frequency converter temperature on the heat sink.
P6.2.8
b
Cold weather mode
ID 2126
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = Disabled; or
1 = Enabled.
Description:
With this parameter, you are able to enable the cold weather function of the causing the frequency converter’s under temp limit to drop
from -10°C to -30°C. This then enables a warm-up feature when the frequency converter is between -30°C and -20°C. The motor,
when given a run command, will turn on for the cold weather time-out and output the cold weather voltage at 0.5 Hz to allow the motor
to warm up. If it does not warm up above -20°C, after that the time frequency converter will fault on under temp fault. If the frequency
converter does go above -20°C, output will begin to follow reference.
P6.2.10
b
Cold weather time out
ID 2128
Minimum value:
0 min
Maximum value:
10 min
Default value:
3 min
Description:
With this parameter, you are able to select the time limit that the frequency converter will run in the warm-up period.
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:
0.0 varies
Maximum value:
1000.0 varies
Default value:
0.0 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 s
Maximum value:
6,000 s
Default value:
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.
P6.2.16
ab
Overvoltage controller response
ID 1840
Minimum value:
N.A.
Maximum value:
N.A.
Default value:
0
Options:
0 = No action;
1 = Warning (W/O S); or
2 = Warning (W S).
Description:
Display options for overvoltage controller warning.
