SVF-G7 Series Frequency Inverter Operation Manual
Chapter 6 Functional Parameter Detail
161
1:Protection
The frequency inverter conducts overload protection to motor through
inverse time limit curve.
Decade:Fault reset times limitation is valid
0: Fault reset is not limit
1: It need to rest 3 minutes if fault happens three times within three
minutes continuously.
Considering the damage caused to frequency inverter due to frequent fault,
this function could be started to protect the frequency inverter, at the
same time, this function could be used to remind the customer to check
whether the parameter setting is valid or not or eliminating whether the
around equipment is normal or not.

The motor will emit heat seriously if running overload in a long time, this
parameter is used to set factor that the frequency inverter conduct thermal

In the situation that the big frequency inverter drives the small motor,
it need to set this function code rightly to protect the motor. When one
frequency inverter drive several motors and run in parallel, the thermal
relay protection function will lose efficacy, in order to protect the motor,
please install the thermal protective relay at the wire entering terminal
or each motor.
