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, turning on the acceleration (RH) or
deceleration (RM) signal varies the set frequency.
REMARKS
A restart (STF signal ON) after ON-OFF of the clear signal (RL) should be made
after more than 1 minute has elapsed. The output frequency provided when a restart
is made within 1 minute is the output frequency given after the clear signal (RL) is
turned off (multi-speed frequency).
