this detection signal is fed back to the inverter, and
its speed variation is automatically compensated for.
Hence, the Weed can be kept if load
variation occurs.
The actual motor speed can be monitored on the in-
verter LED display and parameter unit.
[Application example] extruder, winder, conveyor,
etc.
lnput interface used to set the inverter frequency ac-
curately using external BCD or binary digital signals.
Either 12-bit binary or BCD 3-digit signal can be se-
lected.

.
Input signal format: contact signal input or transistor
open collector (sink type) input
Example: MELSEC AY40, AY4OA, etc.
Gain and offset can also be adiusted.
.
Any three signals can be selected and output as re-
lay contacts,(change-over contacts) from among the
10 standard output signals (RUN, SU, IPFIUVT, OL,
FU1, FU2, RBP, THP, PRG, PU) of the inverter.
The FR-EPG and EPH have one point of relay
outout.
