07-00: Trip Prevention Selection
=xxxx0 : Enable Trip Prevention During Acceleration
=xxxx1 : Disable Trip Prevention During Acceleration
=xxx0x : Enable Trip Prevention During Deceleration
=xxx1x : Disable Trip Prevention During Deceleration
=xx0xx : Enable Trip Prevention in Run Mode
=xx1xx : Disable Trip Prevention in Run Mode
=x0xxx : Enable over voltage Prevention in Run Mode
=x1xxx : Disable over voltage Prevention in Run Mode
07-01 : Trip Prevention Level During Acceleration (%) 50 ~ 200
07-02 : Trip Prevention Level During Deceleration (%) 50 ~ 200
07-03 : Trip Prevention Level In Run Mode (%) 50 ~ 200
07-04 : Over voltage Prevention Level in Run Mode 350.0 VDC ~ 390.0 VDC
700.0 VDC ~ 780.0 VDC
Note:
1. In acceleration, the inverter will delay the acceleration time if the time is too short resulting in the
over current in order to prevent the inverter trips.
2. In deceleration, the inverter will delay the acceleration time if the time is too short resulting in the
over voltage of DC VUS in order to prevent the inverter trips with ‘OV’ displayed.
3. Some mechanical characteristics (such as press) or unusual breakdown (seize due to insufficient
lubrication, uneven operation, impurities of processed materials, etc.) will cause the inverter to
trip, thus inconvenience users. When the operating torque of the inverter exceeds the setting of
07-03, the inverter will lower the output frequency following the deceleration time , and return to
the normal operation frequency after the torque get steady.
07-05: Electronic Motor Overload Protection Operation Mode :
0 : Enable Electronic Motor Overload Protection
1 : Disable Electronic Motor Overload Protection
07-06 : Motor type selection:
0 : Electronic Motor Overload Protection Set for Non-Inverter Duty Motor
1 : Electronic Motor Overload Protection Set for Inverter Duty Motor
07-07 : Motor Overload Protection Curve Selection
:
0 : Constant Torque (OL =103 %) (150 % for 1 Minute)
1 : Variable Torque (OL = 113 %)(123 % for 1 Minute)
07-08 : Operation After Overload Protection is Activated
0 : Coast-to-Stop After Overload Protection is Activated
1 : Drive Will Not Trip when Overload Protection is Activated (OL1)
Description of the thermal relay function:
1. 07-07 = 0: To protect the general mechanical load, as long as the load is less than 103% rated
current, the motor continue to run. The load is larger than 150% rated current, the
motor will run for 1 minute. (Refer to following curve (1)).
= 1: To protect HVAC load(FAN
、
PUMP…so on)
:
as long as the load is less than 113%
rated current, the motor continue to run. The load is larger than 123% rated current,
the motor will run for 1 minute.
