Fig 6.21 Timer Function Operation Example
 Motor Contactor Answer Back Detection
The motor contactors can be observed using the motor contactor answer back function. Therefore an auxiliary
contact of the motor contactors must be connected to a digital input which is set to for this function
(H1-=86). If the contactor close command is set and no answer back signal comes from the contactor, the
inverter detects a SE1 fault (see below). Parameter S1-28 selects if the detection is enabled or disabled and
whether the SE1 fault is reset automatically or if has to be reset manually.
