Parameter Frequency setting by external terminals
FR-D700 SC EC 6 - 57
NOTES The range of frequency changeable by RH (acceleration) and RM (deceleration) is 0 to max-
imum 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 and Pr. 45. 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.
If the start signal (STF or STR) is off, turning ON the acceleration (RH) or deceleration (RM)
signal varies the preset frequency (when Pr. 59 = 1 or 2).
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 E²PROM) invalid
(Pr. 59 = 2 or 3). If set valid (Pr. 59 = 1), frequency is written to E²PROM frequently, this will
shorten the life of the E²PROM.
The RH, RM, RL signals can be assigned to the input terminal using any Pr. 178 to Pr. 182.
When terminal assignment is changed, the other functions may be affected. Please make
setting after confirming the function of each terminal.
