CAUTION
• The range of speed changeable by RH
(acceleration) and RM (deceleration) is 0 to
maximum speed (Pr. 1 setting). Note that the
maximum value of set speed is (main speed +
maximum speed).
• When the acceleration or deceleration signal turns on, the set speed varies according to the slope set
in Pr. 44 "second acceleration/deceleration time" or Pr. 45 "second deceleration time". The output
speed acceleration/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 speed. (Refer
to page 27 for the set speed and output speed.)
• If the start signal (STF or STR) is off, turning on the RH (acceleration) or RM (deceleration) signal varies
the set speed.
CAUTION
When selecting this function, re-set Pr. 1 "maximum speed" according to the machine.
