etection Signal (Z
S
)
Assign the output terminal function 040 [ZS] 0-Hz detection signal to one of [CC-01] to [CC-07] that cor-
responds to the output terminal and output the signal.
This function is to output a signal when the output frequency of the inverter becomes lower than the
level specified with the 0-Hz detection value level [CE-33].
When the feedback circuit board is used, the actual frequency of the motor is evaluated for outputting
the signal.
ZS Signal is switched only by existence or non-existence of speed detection at any control modes in
the following way:
Without speed detection: Output frequency monitor (dA-01)
With speed detection: Frequency detection monitor Absolute values of (dA-08)
Precautions for Correct Use
While the operation is stopped, the [ZS] signal becomes ON state because the frequency is 0
Hz.
