Function 36 Frequency At Reference (FAR)
I
This signal is active (On) when the output fre-
quency reaches the reference frequency.
This is an open collector output.
If the optional relay unit is used, this signal can be
used as a contact output.
FAR: 0.5 to 5.0 Hertz
Starting Actions
Function 37 Starting Frequency
Function 36 Start Frequency Hold Time
Starting frequency set range is 0.5 to 5 Hz.
-- Starting frequency holding time setting range is
0.0 to 10 sec.
A starting frequency and holding time can be set
that is suitable for the starting torque
tics of the load. (Setting is ignored during decelera-
tion and reverse operation.)
Frequency Jump
These functions are used to avoid the natural
mechanical vibration of the load.
Three jump frequencies can be set.
are not active during acceleration and decel-
eration or if the multi-step speed settings are used.
The jump frequency range is adjustable between 0
to 5 Hz. (When the jump frequency is not used, set
it to ‘0.0’.
Jump 1, Jump 2, &Jump 3:
to 400 Hz
