CAUTION
•
The frequency can be varied by RH (acceleration) and RM (deceleration)
between 0 and the maximum frequency (Pr. 1 setting).
•
When the acceleration or deceleration signal switches on, the set frequency
varies according to the slope set in Pr. 44 "second acceleration/deceleration time"
or Pr. 45 "second deceleration time". The output frequency acceleration and
deceleration times are as set in Pr. 7 "acceleration time" and Pr. 8 "deceleration
time", respectively. Therefore, the longer preset times are used to vary the actual
output frequency.
•
If the start signal (STF or STR) is off, turning on the acceleration (RH) or
deceleration (RM) signal varies the preset frequency.
CAUTION
When selecting this function, re-set the maximum frequency according to the
machine.
