● 16: Simple PLC paused
When the terminal is switched on, the PLC running is paused and the frequency
converter runs at zero speed; when the terminal is switched off, the frequency con‐
verter resumes the status before the PLC pause. This function is dependent on the
level of the input terminal signal.

● 17: Reserved
● 18: The second frequency command source enabled
This function is used to switch frequency command source between the first channel
([b1.00]) and the second channel ([b1.16]), which is level-sensitive. When this func‐
tion is inactive, the first channel ([b1.00]) is active; when this function is active, the
second channel ([b1.16]) is active.
If status of external terminals for frequency source switching is changed during run‐
ning, the new frequency command is accepted and the frequency converter acceler‐
ates / decelerates to the new frequency command.
● 19: External fault N.O. contact input
● 20: External fault N.C. contact input
An external fault signal is connected to these terminals and if the signal is active, the
frequency converter indicates an "E-St" error and stops.
The reaction of the functions "External fault N.O. contact input" and "External fault
N.C. contact input" is defined as below:
N.C.:
– If terminal is active (closed), there is no error.
– If terminal is inactive (open), there is an error.
