4.2.2.6 Control modes
The drive provides the following control modes:
- Speed control mode : Default control mode of the drive. The control mode can be used for
applications where constant speed is required, such as pumps, fans and conveyors.
- Torque control mode : used for processes that require torque control (eg, mixers and slave
drives). The torque reference comes from a process control system or a control panel.
- PID control mode : controls the process variable (eg, pressure, level or flow) by adjusting the
speed of the motor accordingly.
Figure 4-5: PID control mode
Application examples:
• Booster pumps of municipal water supply systems
• Automatic level control of water reservoirs
• Booster pumps of district heating systems
• Speed control of different types of material handling systems where the material flow
has to be regulated.
