Functions 7.9 Application-specific functions 7.9.11 Multi-zone control Multi-zone control is used to control quantities such as pressure or temperature via the technology setpoint deviation. The setpoints and actual values are fed in via the analog inputs as current (0 … 20 mA) or voltage (0 … 10 V) or as a percentage via temperature- dependent resistances (NI1000 / PT1000, 0 °C = 0 %;...

The day/night changeover control can be realized e.g. using an external signal via DI4 or using free blocks and the real time clock via p31025. Note When the multi-zone control is activated, the analog inputs are newly interconnected as sources for the setpoint and actual value of the technology controller (see table).
Page 261 Functions 7.9 Application-specific functions Note Please note that when multi-zone control is activated, any BiCo interconnections present for analog inputs and for the technology controller's setpoint and actual value are cancelled and interconnected with the links defined in the factory. When you deactivate multi-zone control, the associated BiCo interconnections are cancelled.

Page 263: Cascade Control
Functions 7.9 Application-specific functions 7.9.12 Cascade control The cascade control function is used in applications that require between one and four motors to be run at the same time depending on load, so that e.g. highly variable pressure ratios or flow volumes can be corrected. Cascade control consists of the speed-controlled main drive and up to three other drives that are switched-on or switched-off via contactors or motor starters, either in a fixed arrangement or dependent on the operating hours.
Page 264 Functions 7.9 Application-specific functions To avoid frequent activation/deactivation of the uncontrolled motors, a time can be specified in p2377 which must have elapsed before a further motor can be activated/deactivated. After the time set in p2377 has elapsed, a further motor will be activated immediately if the PID deviation is greater than the value set in p2376.

Page 267: Bypass
Functions 7.9 Application-specific functions 7.9.13 Bypass In the bypass function, the motor is either operated by the inverter or directly on the line. The bypass control can either be realized depending on the speed via the inverter or independently of the speed via a signal from the inverter or via a higher-level control.
Page 268 Functions 7.9 Application-specific functions When changing over to inverter operation, initially contactor K2 must be opened and after the de-excitation time, contactor K1 is closed. The inverter then captures the rotating motor and the motor is operated on the inverter. Bypass function when activating via a control signal (p1267.0 = 1) The status of the bypass contactors is evaluated when the inverter is switched on.
Page 269 Functions 7.9 Application-specific functions Bypass function is dependent on the speed (p1267.1 = 1) With this function, changeover to line operation is realized corresponding to the following diagram, if the setpoint lies above the bypass threshold. If the setpoint falls below the bypass threshold, the inverter captures the motor and the motor is fed from the inverter.
Page 270 Functions 7.9 Application-specific functions General properties of the bypass function ● y ● Contactors K1 and K2 must be mutually interlocked so that they cannot close at the same time. Shutdown behavior in bypass operation ● If the motor is in the bypass mode, it cannot be shutdown with OFF 1. The motor coasts down after an OFF2 or OFF3.
Page 271: Energy-Saving Mode
Functions 7.9 Application-specific functions 7.9.14 Energy-saving mode The energy-saving mode is mainly used for pumps and fans. Typical applications include pressure and temperature controls. In the energy-saving mode, the inverter stops and starts the motor depending on the system conditions. The energy-saving mode can be activated via the technology controller (without external commands via terminals or bus interface) and via an external setpoint input.
Page 272 Functions 7.9 Application-specific functions In the energy-saving mode, the motor is shut down; however, the speed setpoint and/or the technology controller deviation are/is monitored. ● For an external setpoint input (without technology controller) the speed setpoint is monitored and the motor is switched-on again as soon as the setpoint increases above the restart speed.
Page 273 Functions 7.9 Application-specific functions Energy-saving mode with setpoint input using the internal technology controller In this operating mode, the technology controller must be activated as the setpoint source (p2200) and used as the main setpoint (p2251). The function can be operated both with and without boost.
Page 274 Functions 7.9 Application-specific functions Energy-saving mode with external setpoint input In this operating mode, the setpoint is specified by an external source (e.g. a temperature sensor); the technology setpoint can be used here as a supplementary setpoint.
