CAUTION
⋅ The range where the frequency can be varied by RH (acceleration) or RM (deceleration) is 0 to the maximum frequency (Pr.
1 or Pr. 18 setting).
⋅ When the acceleration or deceleration signal switches on, acceleration/deceleration time is as set in Pr. 44 and Pr. 45. 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.
⋅ 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.
⋅ 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 functions may be affected. Please make setting after confirming the function
of each terminal.
⋅ Also available for the network operation mode.
REMARKS
During jog operation or PID control operation, the remote setting function is invalid.
Setting frequency is "0"
⋅ Even when the remotely-set
frequency is cleared by turning
on the RL (clear) signal after
turn off (on) of 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 turn off (on) of both the
RH and RM signals
⋅ When the remotely-set speed is
cleared by turning on the RL
(clear) signal after turn off (on)
of both the RH and RM signals,
the inverter operates at the
frequency in the remotely-set
frequency cleared state if power
is reapplied after one minute
has elapsed since turn off (on)
of both the RH and RM signals.
When selecting this function, re-set the maximum frequency according to the machine.
