● Variable Type C3
• The unit for the rated motor current, accumulated operating time standard, DC injection braking fre-
quency, startup DC injection braking time, DC injection braking-to-stop time, maximum output fre-
quency, frequency reference upper limit, and frequency reference lower limit is 0.1.
Examples:
0.7→ H’00000007
50.0 → H’000001F4
120 (120.0) → H’000004B0

The communications type is always 0.
(The frequency references set by Digital
Operator keys and by communications
are enabled).

000B Multi-function output selection 000: Not assigned.
001: Zero speed (Output turned ON
when the output frequency is 0 Hz
or operation is stopped.)
002: Frequency matching (Output turned
ON when the output frequency and
the frequency reference are the
same.)
003: Reverse operation (Output turned
ON when the direction of rotation is
set for reverse operation.)
