Learning Advanced Features
When the aux reference value is set to 100%, the final PID reference becomes 100%. In this case,
output frequency of the inverter does not decelerate because the PID output does not decelerate
even if the input feedback value is 100%.
5.44.8 Master Follower
It is used to control multiple inverters with an inverter. When [AP1-40 MMC Sel] is set to <2 : Multi
Follower> or <3 : Multi Master>, it is called as {Leader Drive}. The rest inverters set to <4 : Serve
Drv> are called as {Serve Drive}.
Leader Drive
It is an inverter to execute PID control with PID Feedback from sensor, control Multi Motor and
function as Master of communication.
In addition, if it is set to Leader Drive, Drive turned on at first performs functions of Soft Fill(Pre-
PID), Sleep/WakeUp and Aux Motor PID Compensation).
Serve Drive
It is an inverter to operate motors with Leader Drive.
Each inverter and motor has the same number(ID), [COM-01 Int485 St ID].
Among the operating motors, the motor with the lowest priority is called Main Motor and the rest
of motors are called as Aux Motor.
※
In case that every motor is stopped, the motor with the highest priority is called as Main Motor.
This is, Main Motor and Aux Motor are changed according to the situation and Leader Drive and
Serve Drive are fixed.
