2.8.11.9 Save reference
Saving a frequency reference value using a logic input command lasting longer than 0.1 s.
• This function is used to control the speed of several inverters alternately via a single analog reference and
one logic input for each inverter.
•
It is also used to confirm a line reference (communication bus or network) on several inverters via a logic
input. This allows movements to be synchronized by getting rid of variations when the reference is set.
• The reference is acquired 100 ms after the rising edge of the request. A new reference is not then acquired
until a new request is made.
