PARAMETERS

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

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.
