Frequency setting by input signals
NOTE
The range of frequency changeable by RH
(acceleration) and RM (deceleration) is 0 to
maximum frequency (Pr. 1 or Pr. 18 setting).
Note that the maximum value of set frequency
is (main speed + maximum frequency).
When the acceleration or deceleration signal switches ON, acceleration/deceleration time is as set in Pr. 44 Second
acceleration/deceleration time and Pr. 45 Second deceleration time. Note that when the time set in Pr. 7 or Pr. 8 is longer than
the time set in Pr. 44 or Pr. 45, the acceleration/deceleration time is as set in Pr. 7 or Pr. 8. (when RT signal is OFF)
When the RT signal is ON, acceleration/deceleration is made in the time set in Pr. 44 and Pr. 45, regardless of the Pr. 7
or Pr. 8 setting.
Even if the start signal (STF or STR) is OFF, turning ON the acceleration (RH) or deceleration (RM) signal varies the
preset frequency.
When switching the start signal from ON to OFF, or changing frequency by the RH or RM signal frequently, set the
frequency setting value storage function (write to EEPROM) invalid (Pr. 59 = "2, 3"). If set valid (Pr. 59 = "1"), frequency
is written to EEPROM frequently, this will shorten the life of the EEPROM.
