PARAMETERS
98
Note:1. The frequenc
y
can be varied b
y
RH
(
acceleration
)
and RM
(
deceleration
)
between 0 and the maximum frequency (Pr. 1 or Pr. 18 setting).
2. When the acceleration or deceleration si
g
nal switches on, the set frequenc
y
varies accordin
g
to the slope set in Pr. 44 or Pr. 45. The output frequenc
y
acceleration/deceleration times are as set in Pr. 7 and Pr. 8, respectivel
y
.
Therefore, the lon
g
er preset times are used to var
y
the actual output
frequency.
3. If the start si
g
nal
(
STF or STR
)
is off, turnin
g
on the acceleration
(
RH
)
or
deceleration (RM) signal varies the set frequency.
REMARKS
A restart (STF signal ON) after ON-OFF of the clear signal (RL) should be made
after more than 1 minute has elapsed. The output frequency provided when a restart
is made within 1 minute is the output frequency given after the clear signal (RL) is
turned off (multi-speed frequency).
