ESP production mode
The ESP control program can be used to control motor speed using Manual mode
and Automatic process control mode.
Manual mode
In manual mode, the drive will control motor speed with user defined
acceleration/deceleration ramp rates. Typically, it is desired to accelerate to the
desired production speed range as soon as possible and then switch to a smoother
speed transition style. Specifically for that purpose, the ESP control program provides
two sets of acceleration/deceleration ramp time settings.
You can set the speed reference directly through a desired control interface.
• Analog input
• Fieldbus
• Control panel, and
• Drive parameter value.
