NOTE
• 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, 12, 13"). If the frequency setting value storage function
is valid (Pr.59 = "1, 11"), the frequency is written to EEPROM frequently, and this will shorten the life of the EEPROM.
• The range of frequency changeable using the acceleration (RH) signal and the deceleration (RM) signal is 0 to the maximum
frequency (set in Pr.1 or Pr.18). Note that the maximum value of set frequency is equal to the total of the main speed and the
maximum frequency.
• Even if the start signal (STF or STR) is OFF, turning ON the RH or RM signal varies the preset frequency.
• The RH, RM, or RL signal can be assigned to an input terminal by setting Pr.178 to Pr.189 (Input terminal function
selection). Changing the terminal assignment may affect other functions. Set parameters after confirming the function of each
terminal.
• The inverter can be used in the Network operation mode.
• The remote setting function is invalid during JOG operation and PID control operation.
• The multi-speed operation function is invalid when remote setting function is selected.
When setting frequency is "0"
• Even when the remotely-set frequency is cleared by turning ON the clear (RL) signal after turning OFF (ON) both the RH and
RM signals, the inverter operates at the remotely-set frequency stored in the last operation if power is reapplied before one
minute has elapsed since turning OFF (ON) both the RH and RM signals.
