Mitsubishi Electric FR-F500 Series, Инструкция по эксплуатации

PARAMETERS
94
Note: 1. The frequency can be varied by RH (acceleration) and RM (deceleration) between 0 and 120Hz.
2. When the acceleration or deceleration signal switches on, the set frequency varies according to
the slope set in Pr. 44 or Pr. 45. The output frequency acceleration/deceleration times are as set
in Pr. 7 and Pr. 8, respectively. Therefore, the longer preset times are used to vary the actual
output frequency.
3. If the start signal (STF or STR) is off, switching on the acceleration (RH) or deceleration (RM)
signal varies the set frequency.
REMARKS
This function is invalid under jog operation and PID control operation.
Setting frequency is "0"
Even when the remotely-set frequency is cleared by turning on the RL (clear) signal after both the RH and
RM signals turn off (on), the inverter operates at the remotely-set frequency stored in the last operation if
power is reapplied before one minute has elapsed from when both the RH and RM signals turned off (on) .

When the remotely-set frequency is cleared by turning on the RL (clear) signal after both the RH and RM
signals turn off (on), the inverter operates at the speed in the remotely-set frequency cleared state if power
is reapplied after one minute has elapsed from when both the RH and RM signals turned off (on) .
