Parameter
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 "Second acceleration/deceleration time" and Pr. 45 "Second deceleration
time". Note that when long time has been set in Pr. 7 or Pr. 8, 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 to 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 or 3). If set valid (Pr. 59 = 1), frequency is written to EEPROM frequently, this will
shorten the life of the EEPROM.
The RH, RM, RL signals can be assigned to the input terminal using any Pr. 178 to Pr. 189
"Input terminal function selection". When terminal assignment is changed, the other func-
tions may be affected. Please make setting after confirming the function of each terminal.
Also available for the network operation mode.
