Function
When the output frequency exceeds the frequency set with the parameter F100, an ON
signal is put out. The function of this parameter is to send a signal for exciting or releasing
an electromagnetic brake.
through the open collector terminal OUT1 or OUT2 (24 Vdc - max. 50 mA). (Default setting: OUT 1)
Output terminal setting
The low-speed signal (ON signal) output function has been assigned to the
terminal OUT1 by default. To invert output signals, it is necessary to change
the setting of the output terminal selection parameter.
