Input and output phase loss fault (F17.03 - F17.06)
Ref. Code Function Description Setting Range [Default]
F17.03 The detection base of lack of input 0 - 100 [30%]
F17.04 The detection time of lack of input 0.0 - 5.0 [1.0s]
F17.03 is a percentage of rated voltage of MONT72.
When MONT72 detects certain input voltage does not hit the detection base (F17.03) and exceeds the preset
detection time (F17.04), MONT72 alarms E0015 fault (lack of input).
•
F17.03 or F17.04 = 0 or in the battery driven run mode, MONT72 will not detect input phase loss fault.
F17.05 The detection base of lack of output 0 - 100 [20%]
F17.06 The detection time of lack of output 0.0 - 20.0 [3.0s]
F17.05 is a percentage of rated current of MONT72.
When MONT72 detects certain output current does not hit the detection base (F17.05) and exceeds the
detection time (F17.06), MONT72 alarms E0016 fault (lack of output).
•
F17.05 or F17.06 = 0, MONT72 will not detect output phase loss fault.
Motor fault (F17.07)
Ref. Code Function Description Setting Range [Default]
F17.07 Motor overload protect factor 20.0 - 110.0 [100.0%]
The motor overload protection factor can be set as 100% when MONT72 drives a motor of the same power
class.
To protect the motor when the motor power is smaller than the standard matched power, user needs to set
proper motor overload protection factor (F17.07). The factor can derive from the following formula:
Motor overload protect factor (F17.07) =
Rated current of motor (F07.02 / F10.03)
Rated output current of MONT72
× 100%
Fault auto-reset function and fault relay action (F17.08 - F17.10)
Auto reset function enables MONT72 to reset the fault as per the preset times and interval.
The following faults do not have the auto reset function:
E0008: Power module fault E0021: Control board EEPROM read and write failure
E0010: Brake unit fault E0022: Operation panel EEPROM read and write failure
E0014: Current detection fault E0024: External device failure
E0036: Brake contactor pull-in / off failure
Ref. Code Function Description Setting Range [Default]
F17.08 Fault auto reset times 0 - 100 [0]
F17.09 Fault auto reset interval 2.0 - 20.0 [5.0s/times]
When F17.08 = 0, it means “auto reset” is unused and the protective device will be activated in case of fault.
•
If no other fault is detected within 5 minutes, the auto reset count will be automatically cleared.
•
On condition of external fault reset, auto reset count will be cleared.
F17.10 Faulty relay action 00 - 11 [00]
Bit0: In auto reset process
Bit1: In undervoltage process
•
0: Faulty relay doesn’t act.
•
1: Faulty relay acts.
Note: Relay needs to be set as No. 14 function. (Controller fault)
