Note: 1. The frequency can be varied by RH (acceleration) and RM (deceleration) between 0 and the
maximum frequency (Pr. 1 or Pr. 18 setting).
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
After the clear signal (RL) has turned on, then off, make a restart (turn on the STF signal) more than 1
minute after that. The output frequency at a restart made within 1 minute will be the output frequency (multi-
speed frequency) after the clear signal (RL) has turned off.

4.2.25 Intelligent mode selection (Pr. 60)
Pr. 60 "intelligent mode selection"
The inverter automatically sets appropriate parameters for operation.
!
If you do not set the acceleration and deceleration times and V/F pattern, you can run the inverter as if
appropriate values had been set in the corresponding parameters. This operation mode is useful to start
operation immediately without making fine parameter settings.
!
If the intelligent operation mode has been selected, entry of the jog signal or RT (second function
selection) signal during an inverter stop starts ordinary operation, with priority given to jog operation or
second function selection. After a start in the intelligent operation mode, neither the JOG signal nor the RT
signal is accepted.
