Note: 1. Set 701 in Pr. 77 to enable read and write. (When Pr.
77
=
701, Pr. 22 acts as a parameter for fast response
current limit level.)
2. Use Pr. 73 to switch the terminal 1 input voltage
between 0 to 5V and 0 to 10V.
3. When 9999 is set in Pr. 22, the terminal 1 input is
dedicated to stall prevention level setting. Therefore,
the auxiliary input and override functions of terminal 1
are made invalid.
4. The fast response current limit level is factory-set to
135%.

Pr. 28 "multi-speed, input compensation"
By entering a compensation signal into the auxiliary input termi-
nal 1 (Note), the speeds (frequencies) of multi-speed settings
selected by the
RH, RM
and
RL
terminals can be compensated
for
Compensation
1
by Auxiliary Input
No compensation
(Note) When any of 4, 5 , 14 and 15
is set in Pr. 73, the
compensation signal is
entered into terminal.2.

tionldeceleration in a short time up
to the 60Hz or higher speed range
(S-pattern accelerationldecelera- fb
tion A). In this accelerationldecel-
t
eration pattern, fb (base frequency)
is always the inflection point of an
S shape, allowing accelerationlde-
celeration time to be set according
to the reduction in motor torque in
the 60Hz or higher constant-output
operation range (Pr. 7, Pr.
8).
Note: For the accelerationldeceleration time, set the time re-
quired to reach the base frequency (Pr.
3),
not the accel-
erationldeceleration reference frequency (Pr. 20).
